150 tire install

[Uquackmeup]

I just completed a 150 tire install on a '95 Sportster. If interested, the info can be seen at

[Ray]

The bike looks nice,I like al the mods.Where do you find the rear pully?

[Uquackmeup]

Thanks for the positive comments on the bike. I got my pulley spacer from these guys:

If you meant the actual rear pulley, I got it from Surdylke:

Nice write up Ron, good link to bookmark. The 150 tire looks like it belongs on your bike.:)

[dmh]

what about the transmision pulley ?

[pres41]

:doh I was thinking the same thing, if the driven pulley is spaced out 3/8 of an inch and the drive pulley is not then the belt is misaligned, meaning it can't be running with full contact in one of the pulleys causing an uneven load on the belt ??????

[rottenralph]

For those of you that are concerned about the pulley allignment you need not be. I have had the wider tire mod done here for about 10 years now and I am still on the same belt with 20000 miles on it. I was told then that it can't be done and once again there is proof that it can. With the proper spacing the impact of the offset is marginal. This offset was originally designed tor a BT and the motorcompany bever worried about the angle so why would you???? This is one of those mods you just do and don't worry so much. Cheers to you Ron, glad it worked out.

After reading your how to, I will now do the same jack mod on my swingarm. I just pry it apart everytime and that is a pain. I finally understand the part about the carriage bolts as well. Looks good and I learned a few things here. I will ditch the left side spacers as well. Never gave them much thought just thought I needed them intuitively. Nice writeup.

One other thing. I drive like an idiot most of the time and spend a lot of time on full power runs so if the belt was the weak link it appears to be strong enough to not worry about.

[Uquackmeup]

Ralph,
Thanks again for the original tip on the pulley spacer.

To answer the other questions, I used a laser and also a straight edge for a belt travel check. The front pulley is wide enough to allow for the slight offset caused by the rear spacing. I think it runs truer now than before. Anyway, the belt runs straight, there are no signs of abnormal wear, the tire is very close but does not rub the fender or the belt, and I'm a happy camper.

[rottenralph]

I have the smaller 1/4 spacer. How much clearance do you have with the 3/8ths spacer. My belt clearance is marginal to say the least.

[Uquackmeup]

Ralph, I just measured the belt to tire clearance at .178 which is close to 3/16"

[pres41]

Good thing to know about the belt alignment, I was just concerned that the alignment didn't cause you premature belt wear.

[Shu]

Which 150/80-16 Metzeler tire are you running? ME880??? I see they offer a 150/80-16 and a 150/80 B16. The later (B) one is 153 mm wide (6.02") and the regualr one is 161 mm wide (6.34"). Also the B tire is shorter.

[Uquackmeup]

Shu,
I'm running the "B" version 150, which although listed as being 6.02" is only 5.75" mounted on a 3" rim. Was the other tire you mentioned an 880? I couldn't even find reference to it.

[Shu]

Cool, I'm ordering the spacer for mine and will convert it this winter. Oh and here is a link to the Metzeler 880 tire sizes.

http://www.us.metzelermoto.com/media/m_full_line.pdf

[Uquackmeup]

Shu,
the larger size you mentioned is for a Metzeler "Wide White Wall" 880. I, too, used the link you mentioned as my source for information. I thought I was having another senile moment thinking I missed an important piece of the puzzle.

To anyone else attempting this project, please keep me updated with your outcome. I will gladly incorporate your learning experiences with my "How-To" page.

Thanks all.

[Shu]

The second one is the non B tire and the bottom one is the B tire, both blackwall tires. BUT since you used the B one, that'll be what I order just so that I know it works:)

[newberrykc]

Really nice scoot. Thanks for the write up, I will be doing this soon. I will have to research the tires as I am going with Avon tires. I already have an Avon Venom on the front so I guess I will follow suit on the back....

Thanks again.

[Uquackmeup]

Shu,
I'm sorry I questioned you. It was definitely negligent for me as I missed it even after you pointed it out. It looks like that tire is designated as a front tire.

[rottenralph]

Hey Newberry, I used a 150/80/16 on my 3.5 inch rc comp rim. AM18 supervervenom will work. This is a V rated tire and will fit. I had one the first time I did this change. Really wide, I think it will be wider than the Metz and therefore a little harder to fit but still possible.

[Jason's Sporty]

I think my next tire will a 140-150 thanks to ron's custom work. hopefully with the chain drive I wont have to space the sprocket out any. it clears the tire by a good half inch now.

[newberrykc]

Thanks ralph. I will look into it.. I really want a bigger tire, this is the way to go I think....Thanks for all the good info...

[rottenralph]

Hey Jason, The make offset sprockets for this job anyway but the chain is narrower than the belt so you should be able to go with a wider tire anyway. I was originally told I need to go to a chain if I wanted a wider tire.

Ron has written an excellent how to that is for sure. I am still trying to figure out how I am going to use the carriage bolts on my struts since the holes for the mount hardware are all recessed.

[harleybuilder]

Think this mod will work on a 01 1200c?

[rottenralph]

All rear components are the same so why not. I really don't think the year matters one bit. The swingarm and wheels are all the smae from late 80's to 03 I think.

[stein]

Why diden`t the MOCO deliver this from the beginning, lokks much better now. Did the job last night, on my 00 xl 53C.
Hawen`t been abel to testride it yet, but shure looks great:D :D :D :D http://xlforum.net/photopost/showphoto.php/photo/8856/cat/500/ppuser/638

I'm almost finished with the Dunlop 404 150/80-16 install on my 2000 XLH. Took the advice in the sticky: 3/8 spacer from company recommended and I needed 2 washers on the right side between the swingarm and the bushing. A 1-3/8 long bushing will eliminate need for washers; I'll have to check the Indy tomorrow. If he doesn't have them, they can be ordered from the spacer company.

Clearance between the belt and tire is about 1/8 to 3/16"; plenty there. I installed 2" long 7/16 x 14 bolts in the hub pulley due to the 3/8 spacer and used Locktite Red. I did have to grind the Grade 8 markings off the bolt heads; the raised markings rubbed on the shock bolt (just enough to hear them). I'll have to work on polishing the bolt heads now. The belt alignment looks right; there is no obvious misalignment that got my attention.

The wider tire did cause some problems with installing the caliper; had to take the pads out, get the bushing between the caliper and wheel, then get the axle in (yeah, I could have used a third hand). Anyway, after getting the axle in, the pads slipped in from the bottom pretty easy. Also, the axle is about 1" too short due to the washers and hub spacer; I can't get the cotter pin in the castelated nut. I'm not sure if a nylon insert locknut would give me 2 or 3 threads after torquing the nut.

The look?

I am getting ready to change out my 140/90 kenda which measures 6.25 across to a 140/70/16 kenda for the low profile mean ass look. Going to a 120/70/19 up front. Looks like I will need a new front fender. I did not have the axle problem with my 150. Must be the brand of axle you have because mine works fine.

[trippdog]

ok so I have a 01 1200c and I started out following the info in the sticky. I ended up mocking the bike up several times with different combos. I started out with the 3/8 pully spacer and needed 2 washers on the drive side for pully space on the swingarm. But really the issue I had was with the space in the fender. I got shorter progressive shocks and wasnt happy with the fit in the fender. I ordered a 1/4 spacer and mocked it up with one washer on the drive side. I still wasnt happy with the fit in the fender. Believe it or not I gave it a shot with no spacer and I put one washer on the left side of the bike. This combo is the keeper. spacing in the fender is fine on both sides and although the fit is tight with the belt to clear the tire it fits fine. I will add some pictures tomorrow. Looks and handles great. Oh yeah I went with the metzeler 880's and they look great. 150/80HB-16 in the rear and 90/90H-21 in the front. oh and I didnt use carriage bolts. I had chrome bolts in the fender and wanted to keep the look. so I just got thinner nuts about 1/3 the thickness of the factory nuts. I then shortened the bolts and they fit fine. overall you cant tell the bike didnt come from the factory this way. I guess that there must be differences atleast from 95 to 01 because there was way too much space with the 3/8 spacer.

PLEASE DO POST PICTURES! I have an '00 Custom that is an inch lower than stock in the rear so your results will be very helpful to me.:clap

[Swankster]

Great post, but what somewhat scares me is the method for widening the swingarm. I just wonder if that will compromise the integrity of the steel/welds somewhow? Not a metal expert by any means, any comments?
Swankster
Happy with the seemingly wide Dunlop 140 tucked in tight.

I definitely will post pics. I left my camera at work but should have them posted by tomorrow night.

[lange]

Good article.
I want to know if a avon tire 150-80-16 is widw as the metzeler. If so i would put a avon. My front is Avon. Thanks

[Phelan]

Exellent thread. I will definately refer to this when I convert to a 150, though I want a dunlop tire. Nice to see that you don't have to convert to a chain to make it fit.

[HuggyBear]

Just FYI, I had a spare Dunlop 150/80/16 Harley Davidson tire that I attempted to mount on my 2003 Sporty using the following method and it WIL NOT work since the tire is wider than the Metzeler listing in the post. I am thinking it would take an additiona 3/8" (3/4" total) spacer to accomodate this tire and that is too much in my book.

I am debating about getting the Metzeler or sticking with the original Dunlop style tire and will have to get back with everyone on my choice.

[Predator]

You're right. The Dunflops measure wider than indicated. But I know that the 150 Avon Venom X fits OK

[HuggyBear]

I ordered the Metzeler M880 150/80/16 for the back and a front M880 100/90/19 so I would have matching sidewalls and tread. I am hoping they will be in tomorrow or Monday so I can do some test fitting. I really do hope the rear tire measures the 5.75" that was mentioned in the write-up because it wont fit if its any bigger than that.

Everyone cross their fingers for me!!!

[rottenralph]

My Kenda 140 measured just shy of 6 inches across. Its all in the spacing. I am going to be putting on a 140/70/16 on the back of my bike next. I am looking forward to the new look.

It did take a 3/8 spacer to get the 150 on my 2000 XLH; have gone back to the 130/90. Axle was almost too short. Nice look, premature tire wear with OEM wheel.

Regards,

[HuggyBear]

Got the Metzeler tires in yesterday and the back measures 5.75" just like Ron said it would (yippee). From all the measurements I have taken this should fit. I will hopefully get a chance tonight or tomorrow to mock it up with the tire mounted on the wheel. I'm also in the process of chopping my rear fender so this project is sort of snow balling. I hope to be riding before the end of February!

[HuggyBear]

Got it all mocked up and everything looks great!! I did NOT have to spread the rear forks to get everything in either...it was tight but not impossible. The space between the tire and the belt is just a hair over 3/16", which should be well within tolerance. I have about the same amount of space between the swing arm and the bolts holding the rear sprocket on since I used a washer for additional clearance as outlined in the original write-up. I'm jazzed that everything is fitting so nicely and cant wait to get the fender back on. BTW, I am also using carage bolts and acorn nuts for mounting the fender, as suggested.

When I get everything done and field tested I will post again and try to get some picks!!

Thanks to everyone for their comments and especially Ron for the original sticky!!

[HuggyBear]

Okay, I have FINALLY finished my wide tire installed...I also chopped off my rear fender. This project took way to long waiting for parts and weather and for me to get back in town! I have pics (in the Chopper section under the title (Chopped it Wider), but remember I just got back from a 150 mile shake down run to San Antonio and back (Austin). I am very happy with the look of my bike and the new tires make a huge difference over the Dunlops!! Like I said, I have been to SA and back and no problems what-so-ever. Wide tire install was not difficult at all, just time consuming waiting for parts. The chopped rear fender was sort of an after thought while I was waiting but I'm real pleased with the results.

Here is a list of the things I did:
spaced out the rear sprocket to accomodate a 150/16
installed two new Metzeler M880s
new brake pads while I was at it
chopped the rear fender
installed Sparto brake light
changed rear turn signals to run/brake/turn lights
moved the front turn signals to the fork
moved the rear view mirrors to under the bars...not sure how I like the look of this but the funtionality of the mirrors is way up with my mini-apes.
and added a nifty little tool bag to my swing arm and a tank bra just for fun

[Xman75]

I just did the 150 thingy....With My stock 2001 swing arm ...I did not have to spread it...I used the Dunlop 150/80/16 Harley Davidson tire and a 1/4 inch pulley spacer..had to make the pulley side axle spacer 1/4 inch longer but all seems well....had alittle problem with the lower belt guard but I think I have that resolved.....Going to test it as soon as I get a good day...What I need to know is...How much air pressure should I use? and What is the minimum clearance on the tire to belt space?.....I will post pics soon....Thanks

[rottenralph]

Here is my 150/80/16. I got cheap and bought a street shark tire because I wanted to secure the right look and fitment before spending a lot on a tire. This is the the sixth tire this year due to some mods I have been trying(front and rear). Actually feels quite sticky so I will let you guys know if it is crap or not. http://www.clubchopper.com/photopost/data/500/medium/Picture_0601.jpg

Thanks for the write up!!!

I read an article years back about fitting a 145 tire to a 99 Sporty, but lost it. Everyone I spoke to said you couldn't increase the tier size. I've been looking around for someone's experience with this!

[hikerbiker]

Whats the largest tire anyones put on a 06 1200 C sportster ?

[Wolfden]

Great writeup .. I'v been asking about tires , mostly rims thu , but I was very happy to see this post , now I have a starting point over the stock size . now if I can just get the rim issiue solved I'll be ready to start buying parts . All I want is nice 60 spoke rims , so if anyone has one or a set let me know maybe we can work something out :)
Thanks
Wolf

[ReddTigger]

I upgraded to the 140 last year, without spacers, and it's a nice improvement over stock.. The 150 will be my next stop when I need new Rubber...

BTW I have over 5000 miles on the ME880 and Still plenty of rubber left.

[bigshaff44]

Has anybody actually done this with an Avon? I see where somebody says it should work, does anybody know for sure.

[Predator]

Has anybody actually done this with an Avon? I see where somebody says it should work, does anybody know for sure.

Yup. I put on an Avon VenomX 150 without problem. I'm not using spacers but I am running a chain conversion. The chain is slightly narrower than the belt but I have at least 1/4" space between the tyre and the chain. Should be ok with the belt but it'll be close.

[rottenralph]

Back when I originally did my conversion to a wider tire I used a super venom 150/80. It will fit fine but I think you can forget it without doing some spacing.

[bigshaff44]

I see that Avon has 2 sizes of the 150 Vemon X. Did you use the 77V (6.2") or 77H (5.9"). I was thinking about try the 77V, but from my measurements I will need a 1/2" pulley spacer, would that be to much?

[sdjr]

I'm thinking about this conversion, but let me ask...will the 150 still fit if the shocks have been lowered to progressive 11"s?? does shock height make a difference? Thanks.

JR

[Xman75]

I had not problems with the shocks.....

http://xlforum.net/photopost/data/653/150_tire_test1.jpg

[biknut]

WOW!!! This is the most exciting thread I've seen on the forum since reading about setting the squish.

I have been planning to try to run a 150 tire for a long time. This thread eliminates both of the sticking points that have been holding me up.

Number one, just put a 150 tire on the stock wheel. I thought you would need to go to a 4".

Number two, just space out the rear pulley. I've been trying to figure out how to space out the front pulley. I never thought about just doing the rear. That's really thinking outside the box. When I think about it now, it makes since to me. The difference in angle to the rubber teeth on the belt isn't really that great.

On top of all this, my GMC swing arm is already wide enough to handle a 180 tire. Nothing to stop me now. Wouldn't you know I just ordered a new tire 130tire last week. Looks like I'll be sending it back now for a bigger one.

[Xman75]

Ya mus Be frum TEXASS!

[bigshaff44]

I just got done stuffing an Avon 150 (77H) on my 01. I had a few minor setbacks but I think I am in good shape now. I ended up needing 3 washers on the right to keep the pully bolts from rubbing.If you run into that problem I would suggest super glueing them together, it will make it easier to hold when you slide the axle back in. Also I stuck a socket extension through the left side to hold the spacers up while I was messing with the washers. I had to bend out my chainguard just a hair. I also had to use a thinner washer on under the castle nut on the axle in order to get my cotter pin back in. The biggest problem I had was the lip of the tire rubbing on the left side. It was fine with just me, but when I went down the road with my wife on the back I had a problem. I ended up grinding down the fender support bracket that back fender bolts screw into to get clearence. I also had to grind down those bolts so they weren't sticking out past the bracket. Make sure you check this real close, I wouldn't have seen it in time if I wasn't out of gas and had to stop before taking it out. I would recomend giving the shocks a good workout to simulate hard bumps to make sure you don't have a problem. I am just glad I cought it before I had a blow out.

[Coxbow]

Hi,

Just to tell you I did the conversion to a 150 Metzerler on my 2003 Sportster Custom without any changes, the only thing a did is not put the belt guard back (not the iron one, the plastic one that prevents water to "splash" everywhere...) and that's it !

Great look !

[rev1970]

i have a spaced rear pulley the front is stock also and drive like a nut i have like 25k on my bike same belt i had to take my lower belt guard off to

[1fast2liter]

all good info. so a 2002 would only need the wider tire and not put on the lower belt guard? that seems simple enough.. did you still have to clearance the fender with the carrige bolts?

[gargantus]

What about metzelers white walls? they seem wider than black walls.. anyone tried to mount one? or know how it will come up?

[KC8YSG]

did the 150 mez and it looks good.

Also got a 150 (Metzeler ME880 Marathon) on my 2003, didn’t change a thing, just didn’t put the anti-splash tuff back on that’s all, only got 1mm between the belt and tire, but I’ve done 4000 miles so far and no problems .

So you're saying you didn't do the offset or the carriage bolts?

[Coxbow]

didn't do squat !

[ReddTigger]

Well I just had go grind off a little of the turn signal stem, it was rubbing against the tire when I'd go over really bad roads. I thought I'd be ok with the 13½" shocks.

[Coxbow]

A friend did the same yesterday, but since there wasn’t a Metzeler available he took a Dunlop/Harley Davidson instead, well there’s a clearance problem, the belt touches the tire ! so we took an old disk brake as spacer (just kept the inner circle without the braking surface of course !) And it was just about enough (he’s going to buy spacers though, but till then…)

[ReddTigger]

Good luck on the spacers, seems he should verify the actual spacing. I think the rotors are a lot more then the 3/16" spacer I used.

[Coxbow]

I see him on Friday, I’ll ask him if it went well…

[1fast2liter]

i was looking at this mod.. i figure if you can put it all to geather with no spacer for 2000 to 2003 then a 1/4 inch spacer for front and back would allow you to use the stock guards. and since the brakes are still loacted were they are you would theoretically only need to re space the sprockets.

[rottenralph]

I used spacers on the rear only. 6.5 inches is the absolute widest you can go. Kenda challenger 140/90 is as big as you can go. I have not found a 150/80 that is as wide as the kenda. I actually rubbed under the fender on the bolts.

[frozen hog]

thanks for the info i may try this next time around

[Bruce]

You have to be carefull with the front spacer. I could only go about .100" and still have a full nut of threads on the trans. output shaft. I also used a 3/16 spacer on the rear.

[1fast2liter]

so .100 is ten thousandths of an inch.. not alot. i know some one makes a offset sprocket for wide tires sportys.. i think pipedreamz.iz has one.

[rocketbikex]

i did it to my 97 with an 150/80/16 me880 and a .300" spacer. plenty of belt clearance, the pulley bolts needed more clearance then the one washer the website advises, but that was easy enough to remedy. it went fairly smooth otherwise. i'll post pics lata.

What do you mean the pulley bolts needed more clearance?

[rocketbikex]

i mean the bolts that hold the pulley to the wheel hub were rubbing the inside of the swing arm, that is why the write up in the link from the first post said use a 1/4" washer, well that wasn't quite enough so i ground a little off the bolts and viola, clearence.

[ReddTigger]

I had to use two spacers, but that was mostly because someone bent up my sprocket cover and it started rubbing. Prior to that I didn't need but the one washer.

I have to get a longer axle shaft as the one I have now is currently just making a smaller cotter pin and using a thinner washer.

[Coxbow]

Good luck on the spacers, seems he should verify the actual spacing. I think the rotors are a lot more then the 3/16" spacer I used.

Anyway, it fits with just a rotor on the pulley's side ! and that's beause he didn't use Metzeler 150's like I did (didn't have to put a spacer at all !)

[kowboi]

OK, so I lowered my 2001 xlh 2" using the Progressive kit in the front forks and
11 1/2" Progressive 418's in the back. Does anyone know if there will be a clearance problem if I go with a Metzler 150? I've wanted to do this mod for a long time and never could get any info till I found this forum.

You might run into a problem with rubbing.. you'll need to make sure that all your interior bolts are button head allen or Carriage bolts.

Depending on how your turn signals mount that may be an issue.

I had to grind mine down a little when I changed the preload on my shocks. and I have 13½" progressives.

[duckman1]

What about 10" shocks, anyone?

[ReddTigger]

What about 10" shocks, anyone?


Good Luck. Tell us how it works out :)

I don't think that 10" shocks will work with a 150.. Just to close to call.

[Spaceman]

I would love to get a fat tire in the rear.

[dwhaley58]

Does anyone know if this 150 tire swap will work on a 2000 883?

[rottenralph]

Yes it will work if you follow the instructions in Uquaqmeups writeup. Fender clearance is fine with shorter shocks asd long as you use carriage bolts for the fender mounts. If you have nuts on the inside you ill probably rub on the inside.

[duckman1]

Ralph, was that an answer for the 10" shocks and 150? I still have a pile of parts to go on my '02, including the 10" shocks, -2 fork kit, bars, seat, new 16" front and rear wheels from Black Bike(black powdercoat). Still trying to decide on the tail light mounting location (side mount), and what pipes and rear tire to run, as well as if I should go to mid-glide triple trees or mill the oem fork down a tad for tire clearance.

[capri302]

I know the last post on this subject was over 5 months ago,but.... is it possible to fit any make of tyre,in the correct size of 150/80/16,or do they vary,in the width, from one make to another? I have the chance of getting a Pirelli,and was wondering if it would be the correct width?! Thanks.

[ReddTigger]

I Don't think anyone has tried the Perelli in the 150 on the solidmounts yet. So be sure to let us know how it goes :) WINK WINK !!

[rottenralph]

Measure the width of the tire. The fattest tire I have used was actually 6 1/4th wide at the fitest point. It was actually a Kenda Challenger 140/90/16. My avon 150/80/16 was also just about 6.25. Over width you will hit the bolts on the fender and chew up the tire.

[majormadowl]

anyone running the Avon venom x on their sporty? jsut put one on my 2000 sport (89 ss motor...super g carb..nitro bottle)...looking for reviews on the tire. Madowl

I used a 3/16" spacer and my tire cleared the belt no problem. I needed to add 2 large washers to the outside of my bearing spacer to clear my sprocket nuts from hitting the swingarm.

I got the space from Vulcanworks.net

[cycowrencher]

Thank you. I now have this winters project.

[hawkbull]

I got the 5/16" spacer and now I clear my belt pretty well. I don't have any alignment issues either. I also had to use a couple of large washers to keep the sprocket bolts from hitting the shock bolt.

[Sporre96]

I made an 6 mm spacer and used 4 mm washer, and i use venom x 150/16/80. Works great:banana Start calculating boys...;)

[aphexandy]

I'm very interested in this (need a new rear soon) but is it just me or does the link to the write up not work?

[lowstature]

since geocities is gone, I can not view the write up.... anyone have it saved or linked elsewhere?

Thanks!

[Gone]

since geocities is gone, I can not view the write up.... anyone have it saved or linked elsewhere?

Thanks!

I have been looking for it too.

[ArizonaFalconer]

I saw the initial write-up, but I would really like to see another step-by step writeup so that I can perform this mod on my Sportster in a few months, as I'll be needing new rubber soon.

[Tres Wright]

Bummer, I would have liked to see the writeup as well as I'm looking at a wheel/ tire swap on my Sporty. The spacer and washers are pretty self-explanatory, but after having read the whole thread it sounds like the original writeup may have called for spreading the swingarm rails for some extra clearance? Also it sounds like the pulley bolts need to be ground down or swapped out so they don't hit the inside of the swingarm. Turn signals may also need to be ground down inside the fender. Anything else?

[capri302]

I have just done this to my 2000 1200. I read the initial write up's,so had the general idea in my mind. I fitted a Metzeler ME880, 150-80-16. The bit you mention about spreading the swing arm is just to make it easier to fit the (extra) spacer between the swingarm and original HD spacer.This is used to get the clearance between the pulley bolts and swingarm (because of the pulley spacer!). I also ground a little off the pulley bolt heads, so that the extra spacer didn't have to be too wide! I also changed the bolts that mount the mudguard (fender) to the rails. These were changed for round headed (carriage) bolts,which I also ground a little off,just to help in the clearance department! As for the indicators, I have fitted some aftermarket items (Kellerman),which I fitted in the original mounting indicator holes,anfd they seem to be recessed just right,so no clearence problems there. But I think that if you use the HD indicators,which are mounted to the covers over the rails,I think you should be fine. And in all honesty,unless you carry lots of lugguage and a pillion,I doubt that you would get that much movement in the rear suspension,that the tyre would come into contact with much under the mudguard. Hope I haven't confused you even more,but it really isn't too hard,and really worth the effort.

[Tres Wright]

Thanks for the info! Did you use the 3/8" spacer? Did you have to go with longer pully bolts?

[capri302]

No use keeping it to myself! Yes,I used the 3/8ths spacer from Vulcanworks, and I didn't need to use longer bolts. The only other thing I found was,when the castleated nut,on the end of the the wheel spindle,is torqued up,there just isn't enough room for the split pin! I would imagine that a "Nyloc" nut would suffice,or if someone was able to machine the nut down a little,that would also do the trick!

[ReddTigger]

I used the 3/16" spacer and a thinner cotter pin and a thinner washer under castle nut, but was able to get it down.

[capri302]

Yep,that's worth a try!

[Tres Wright]

Great, thanks again for the help! Time to go order some stuff :laugh

[rottenralph]

If you guys need some additional inspiration look up the thread from biknut about his 150 install the right way. It was the expensive way with a pustom pulley but it is the nicest install I have seen. I did it like uquakmeup in 95. The only part I did not do is spread the swingarm with the scizzor joack till I read it here. I used to go thru hell trying to get my spacers in until then. My belt has tleast 30K on it without spacing the pulley.

uQuack used carriage bolts in the back to get a little more room for the tire in the fender. He used a scizzor jack to spread the swingarm a hair. I have an extra spacer inside the swingarm to make the bolts clear just fine. My 93 sporty has the curved rear struts and that rear bolt was the problem for me so I cut my struts and put led signals in them.

My take on 150 rear tyre on 1200C sportster 2003.
Tyre: Metzeler ME 880 Marathon 150/80 B16 TL 71H M/C
No way without pulley spacer – drive belt locking against tyre.
3/8 spacer and about 2mm thick spacer on axle to get clearance to lower right shock bolt.
(Yes I mix units – just like NASA)
Had to grind off half thickness of bolts in rear fender – for blinkers and holding fender.
Did not have to move blinkers. Belt close to, but clearing tyre. No problems with axle cotter pin.
Looks cool. Runs fine, also in rain.

Eh, a few days later. Some mountain road fun with missus behind me. A bit too much weight (more me than her) so some grinding on sides – some melting rubber from contact with rear mount of rear fender. No problem with function but looks ugly… :censor

I will probably widen rear fender a little with scissor jack. And actually use some sandpaper on the melted tyre corners.

[Robotech]

I am currious would it be possible to mount an 04+ fender on a pre-04 Sporty? I understand there are difference but just how many? Would this solve the fender mount clearance issues?

(I haven't been able to measure but I'm guessing the 04+ fenders are substantially wider than the pre-04s)

Tobacco, did you use carriage bolts to hold on your fender or just grind down the nuts/bolts that came with the bike?

[capri302]

Just to put my 10 cents in! I think you would have to spread the mudguard (fender) rails as the fender is,obviously,wider, so that would defeat the object of what you were trying to achieve. The later frame, '03 onwards,is completely different so...... Also,I used carriage bolts on mine,and just to give it a little more room (not that it really needed it), I ground a little off the heads!

[Robotech]

I just like the look of the wider tire. Filling the fender isn't as important. :) Hence the curiosity.

However, since I can't see the original guide...is there any special instructions for spreading the swing arm with the scissor jack? For instance, is there a certain spot on the swing arm where you should place the jack as to not damage the swing arm's integrity? Is there a general rule as to how you know when you've spread it enough?

I could probably figure this out but I like asking questions and having the process very clear in my head before I go modifying things that my wellbeing depends on. :D

[capri302]

I put the jack where the axle/spindle goes through the swingarm,and spread it 1/2",that way,when it moves back as you unwind the jack,you still have enough room to get the spacer in! As for the integrity of the swingarm,if you hear any cracking or other unusual noises (which you shouldn't really,it's quite flexible!) you've gone too far!

Well, I did just grind the bolts a bit, like 50% - easy on a lift - just remove the shock top bolts and drop the swingarm. Then ask missus (if she is a power lifter) to raise the swing arm after some grinding (this sounds baad - I realize that) to see if the bolt heads are clear. Hmm.

I also unscrewed (here we go again) the rear bracket inside fender - this turned out to be made of 'spring steel' (OK, I am Swedish - don't know what the :censor it is called) and did not change shape when prying and poking a bit. So I did some more grinding on the 'little button on the inside' - and actually managed to also widen it just a little in a vise (vice?, that thingy gangsters crush heads with). I guess one could also grind a bit from the rubber grommets inside the fender to make the re-installation easier - but I did not have to do that. And remember - all this can be done with the wheel still in swing arm. I did not check all the way up and paid for that by ugly melted corners on my new Metz-s. I have to lean like Rossi to grind those down.

This is proper HD fine tuning - powergrinder - pry bar - medium sized sledgehammer - anvil - power lifting missus - yes I have tattoos. ;)

I have a 2003 883r. Im ready to make an order on 150/80 16 avon roadriders. the rear has an overall width of 150mm (around 5.99 inches??) I also need to order a spacer of 3/16 inches? as for the front can I fit a 100/90 19? Im lookking for some feedback before I do it. WILL IT WORK?????? Thanks guys. I did read all 13 pages too. lol

here is the link to the tires. Great prices

[hooligan75]

wish i saw this thread a few weeks ago. would have saved me alot of trial and error, and rubbing of the new tire.

[Kman Harley]

Okay...I've searched and searched and even PM'ed people asking for help with this and have had no luck with answers so I'm giving in and just going to ask here. I am trying to find exactly all that I will need to do this since the article is not working? I see I need a pulley spacer for the wheel 3/8th" size but what about the front one and will I need anything for the axle also? I think I understand or can figure out how to do it once I have the parts needed but I just want to clarify what all I will need for parts? Also a place where to get the parts I will need, I see the vulcan site for the pulley spacer but am unsure if that's where to get other bits if needed.

HELP PLEASE SOMEONE!!!! LOL Thanks in advance for help.

[hooligan75]

when i did mine all i needed was the pulley spacer and a new larger axle spacer and a longer axle, forget what size of axle spacer exactly.

i had material for the axlespacer here so i just cut a few different sizes till i liked the spacing on the pulley side. i got rid of the bike or i would show you pics.

[Kman Harley]

Thanks for the help, see now that's the first I've heard about needing a longer axle. Be interested in hearing what others did and I'd prefer if there's just a list of stuff to buy cause I don't have a whole lot of tools for fanning up washers and shims, unfortunately. Man just wish the article was still active cause I'm jetting close to taking the back end of my sporty project and I need to order new tires also.

[ReddTigger]

Metzeler ME880 is the brand.

I added a 3/16" spacer on the rear pulley

http://vulcanworks.net/store_4/images/T/rearpullyspacer.jpg
(http://vulcanworks.net/store_4/product.php?productid=333)
and added two large washers on the right side of the axle, between the spacer and swing arm (to allow the pulley to clear)
I also had to install a slimmer washer on the castle nut on the axle.

I could have gotten away with only 1 washer, but I have a chrome pulley cover and it adds to it. If you have a stock pulley, then you should get away with just the 1 spacer.
Basically I followed the information here..

[rottenralph]

I ran mine without any change to the front pulley and never had any belt problems. You will need additional spacing on the axel equal to the spacer for the pulley. Spread the swingarm a hair with a jack screw type jack. The spread part is important or you will have a hell of a time getting the inside axel spacer in. You will have very little space between the belt and the tire but a little is all you need. I used my stock axel with a thinner washer and stacking washers on the inside right side of your axel is the easiest way to do it. Redd's advice is really good.

[Kman Harley]

Thanks, I seen that post. Read the whole thread actually, but the part with the washers and now axle length are the missing details. You have anymore info on the washers, size, did u make or buy them? Any more info at all... Thanks for the help, at least I'm getting some info now

Thanks! So I'll either need a new spacer for the axle that's 3/16th" longer than the stock one or get an additional one 3/16" to add in? Did u have to get a longer axle? If so can you point me to where I can get one? Thanks again.

[rottenralph]

Here is a pic. of the stacked washers. I know the ID is 3/4's and I suspect the OD is around 1 1/8 to 1 1/4 inch. I went out and took a pic. so you can see how the stacked washers look and where they go. http://xlforum.net/photopost/watermark.php?file=59909&size=1

[hooligan75]

i could have used thinner washer on the out side and stacked a couple of washer for axle spacer, but i wanted to maintain stock appearance rather than have it look pieced together.
most people may not have noticed, i would have though.

[Kman Harley]

It's a bit hard to tell what's what, I see the stacked washers and it looks like your chain sprocket is to the top of the pic which I'd assume is bolted to your rim but then what's the part to the bottom of the pic with the aluminum welding? If I have it wrong can you explain plz? Also another pic from the same angle but zoomed out a bit would help. Sorry to be a pain, I just wanna make sure I get this right. Also those washers look simple enough that I should find them at the hardware store, the other stuff like the spacer and possibly axle is what I'll have to order cause there's no shop here that will have anything like that.

Oh and about the axle, did you have to buy a longer one or your stock one was fine? ;)

[Bruce]

I agree with RT. I also used a 3/16 belt pulley spacer, not a 3/8. Got it from Vulcan. They are also making the offset front drive pulleys now, but you should not need one. I used a bottle jack to spread slightly and some 3/4 washers. Slows or any hardware store should have them. Remember to locktite the pulley bolts and check for bolt head clearence for the swing arm. Some on here have had to use a longer axle, some haven't, just depends on how it works out. There will be some trial and error until you get it to fit right.

[Kman Harley]

Cool, thanks Bruce that helps. I guess I'll just order the pulley spacer for now and hope for the best that I don't need a longer axle. If I do end up needing one then that'll be more down time but oh well so it goes.

[rottenralph]

I have a JMC aluminum swingarm. I took a pic. of the axel so you could see the stacked washers. I had the same setup with the stock swingarm.

[Kman Harley]

Cool, that explains the aluminum part that was confusing me.

[Kman Harley]

So I was about to place my order and the Vulcan site does not have my country listed so I can setup my account and place my order. I've e-mailed them but thought it wouldn't hurt to as if anyone knows any other sites to get it from? I've been searching the internet but since this is new stuff to me I wouldn't mind some help from the pros.

edit: I found this (http://www.debrix.com/3-16-Steel-Rear-Sprocket-Spacer-Harley-Big-Twin-p/19-0128-vt.htm) but not sure if it'll work?

Edit 2: Never mind I got my order placed with vulcan so now to place my tires order :) I'm stoked! My build/restoration is nearing completion.

[fordpaul]

I'm getting confused here! I'm an Engineer by trade, so I'm really struggling with some coments that say they have used a spacer on the rear sprocket, or pulley, but not needed anything behind the front. Doing this must have the effect of missaligning the two faces, resulting in premature wear of both sprockets, and chain.

[rottenralph]

I am not sure how long you expect the belt to last. Mine made it 20K and that was o'k with me, I removed my perfectly good belt and installed a chain now. You are right that a minor misallignment will exist. I will leave it to you to calculate the impact. Maybe you can share your findings. I suppose it is all about what you want and what you are willing to live with. I like my 150/70/18 on mine. The only one that I know that had 400 dollar pulleys made is Biknut and his writeup is supperb. If you want it perfect check his very detailed thread on his rear tire 150 fitment.

[fordpaul]

You guys have already done the mods, so you know what works. I'm just trying to get my head around just offsetting the one sprocket. I guess you have more clearance now with the chain instead of the pulley.

[rottenralph]

I used the chain only because I have an extended swingarm. I agree that intuitively the side loading of pressure on the belt because it is not square on the pulley should tear it easily. Fortunately the belts are really strong and they seem to take it fine. I also imagine a rubber mounted engine moves and provides the same kind of side load when it is moving around. Just a thought.

Actually it affects it less than you think. My front pulley is slightly wider than the belt and when the stock tire was on there the belt road about in the center of the front pulley. With the spacer on, it road on the outside of the front pulley but showed no signs of wear on the edge of the belt that rubbed up against the "lip" on the outside of the pulley in over 20K miles.

[dnice203]

Can anyone tell me where I can locate the link for this install? thanks!

[ReddTigger]

The original link was attached to a Geocities account. Geocities has since gone away. Don't know if anyone copied the information.

[gra4er]

Is there an easy way to know what spacer I need? Can I tell by year or do I have to measure?

[DBH]

When I started mine I thought I knew what I needed from some comments of others that had done it. But when I did it I had to order a wider one. 3/16th wasn't enough for tire clearence I had to use a 3/8th spacer. I used an Avon Venom that is about the widest 150 out there so that is probabley why.

[gra4er]

So the Avon is the widest out there? What is the stickiest? Shinko? That's what it was for my rocket anyway.
