View Full Version : Does your transmission whine when you let off the gas?

My transmission has always whined pretty loudly when I let off the gas in all gears except 5th. I asked the stealer about it when I first started riding it, and got the usual, "they all do that" response. I was riding with some of the guys from the forum yesterday and XL 1200 Custom noticed it and said his didn't do it. I asked stingray about his and he said he's never heard it, but he wears a ff helmet.

Does yours do this?

Make sure your primary chain isn't adjusted too tight.

Sounds are SOOOOOO subjective....

I have been an audio engineer for so long...I'm trained to pick out every single nuance of any sound....among many! I certainly heard things that alarmed me many times when I got my first Sporty.......

That being said, if there is a NOTICABLE whine in your primary, chances are excellent you MAY have a primary chain that's too tight....might even only be in one place on the chain!

When its checked, I recommend you take the plugs wires off the plugs, and "tap" the starter to move the chain a bit...check it.....do it again until you are either SURE there is no tighter spot, or you find the tighter spot....

Adjust to spec at THAT point......

If it were a primary chain issue, wouldn't it do it when I am ON the throttle, as well? And wouldn't it do it in 5th gear too?

And, Chuck, it's VERY noticeable. XL1200Custom heard it when he was on my right as we were coming down an off ramp. It's THAT noticeable!

On your right, huh?

Cam gear noise, perhaps? Or a failing bearing on the camshaft??

Ya gotta isolate it...

Try accelerating and decelerating in neutral....If ya hear it then, use a screwdriver as a "stethescope" to locate the noise....

If ya DON'T hear it then...inspect your drive belt for unusual wear....

Nope, it only does it when the bike is in gear and the clutch is out. If I pull in the clutch, it stops. That's why I think it's the transmission.

My point in saying he was on my right was to illustrate how loud it is. He could hear it over his and my pipes.

It sounds similar to a jet engine winding down. Only happens as I'm decelerating. If I give it the gas, it stops. I figure it is something that happens when you put reverse pressure on the gears. Like I said, too, it only happens in gears 1-4. It doesn't happen when I let off the gas in 5th.

It's done this since I got it new. It doesn't affect the performance, and it hasn't changed in almost 2 years.

BTW, how do you accelerate in NEUTRAL?:laugh :doh

Also, I can't bend far enough to use a screwdriver as a stethescope while I'm going down the road....

My '05 1200c has done it since day one. Only in 3rd and 4th. Dealer mechanic said it's b/c those gears are cut differently than the others.

16,000 miles and no problems; just a bit noisy when I let off the throttle in those gears.

He's 15 and has been riding motocross for years. I let him ride in safe areas around their house. Never fails to put a grin on his face.

May be way off base here but I would check the clutch release bearing. First the adjustment then the bearing itself. The fact that the noise goes away when the bearing is stressed indicates that it could be related to the release bearing. Also, what lube are you running in the primary?

Thanks for the idea, semjpm!

I haven't done any of the service myself, yet, so I'm assuming that it's the standard harley lube. I've been using the HD syn3 oil for oil changes since the 2500 mile, but I doubt that they put that in the primary, since I didn't ask them to. Do you have any recommendations?

biknut
1st May 2007, 17:32
Usually whine is caused by something being too tight. Have you checked the primary chain? HD shops are notorious for adjusting primary chains too tight. You have to check it with a hot motor. Check it in 2 or 3 places. Seldom to primary chains wear evenly.

I voted "no" because my 04 1200 only whinned after my 5 and 10K service until I got it home from the dealer and readjusted the primary myself.

Did you just adjust the nut on the bottom of the primary, or did you have to pull the cover off to do this?

jnlee3
1st May 2007, 18:23
I voted yes but I think it is just the different noises I'm hearing when engine braking and the stress on the gears while doing this. It is not nearly as loud as what you are describing though.

My HD mech told me the primary was too tight when I brought it in for the 5k service and he adjusted it accordingly. The bike seems to accelerate much easier now. It took a little getting used to as I would have to shift quicker and slow down a little as I was speeding too often.

No you don't have to pull the cover. Might want to check your manual; both an allen and nut are involved.

when i put a new belt on my bike it started whining when i let off the gas then kept progressivly got worse where it whine all the time. i think i had the belt too tight , so i loosened it and it wasn't as bad, but it didn't go away. then i checked the level of the fluids in the primary and found it to be low so i filled it up and the whining went away after about a week.

I'm using Harley Formula+ in the primary. Syn3 is too thin. I also had good results with Mobil 75/90W gear oil but it does have some moly in it and that is supposedly not good for the clutch.

I would change the gear oil and check the primary chain when very hot. The tightest spot should have 1/4" of free play.

Mine just started doing this today because I have the primary chain just a tad too tight.

I had the primary cover off to replace a leaky gasket, and when I used the Hero method to set the chain tension the bike wasn't completely warmed up.

Shortly after I started my test ride I heard the primary whining. It was getting late in the day, so I just parked it and will fix it tomorrow.

To find the Hero method, use the Search function.

I think the fact you have an '05 with straight cut gears has something to do with it. Straight cuts are stronger than helicals, but make more noise and are harder to engage. I'd say if your bike is '06+ and you hear a whining noise you should check your primary. On a straight cut bike, you have to live with it. If you are concerned then check your primary chain, but I HIGHLY doubt you have a bearing failing or anythinh like that. You feel some vibration with the whine if that were happening.

My last bike, a Suzuki GSF600 Bandit made a "whirring" noise. I have heard metric cruiser go past me that make that same whirring noise, which I believe is related to their trannies and camchains. The sound like an electric motor. I know the 1200 version of that motor also makes that noise, as I read a couple reviews of the bike before I bought it and the mags noticed the whirring too and commented all air/oil cooled first gen GSXR engines make it.

If your primary is adjusted correctly, stop worrying about it as every motorcycle I have owned made some kind of gear related noise. On a Harley it is more pronounced because you do not have water cooling to muffle the mechanical noises inside your cases.

Oh Yeah :) I hear it on my '05 and it doesn't concern me. I have never owned a water cooled motorcycle so I guess my ears are used to some noise out of a bike.

I have also learned that if you over tighten your primary chain you WILL feel it in the form of drag on movement, like a brake dragging.

So why doesn't it happen in 5th gear????:geek

28th May 2007, 20:21
Prolly because 5th gear is turning slower than all the rest and/or at the speed you're engaging 5th you just can't hear it over the other noises like wind etc...remember, you're always downshifting out of 5th to a higher RPM at a lower speed. I bet if you run fourth gear up to 60/70 MPH you won't hear any whine because of the peripheral noise.

Then again, I could be completely wrong and your tranny is set to explode into flames any minute now :smoke

Nope. TOTALLY quiet in 5th gear. If I downshift to 4th at 60, it's the loudest. It's actually quieter at the equivalent rpm in 3 and 2, and it's practically unnoticeable in 1st.

Welcome to the Forum, sailormi! The correct level for the fluid is just to the top edge of the transmission inspection hole that's covered by the derby cover. It should be just about to the top of your primary chain on the bottom of the transmission sprocket.

I'm still trying to figure out if there's anything that can be done to stop the noise. I'm taking it in for the 10,000 mile checkup soon, so I'm thinking about asking them to leave a little more slack in my primary chain to see if that does it.

When I adjust my primary chain to spec, it whines for a couple days or longer or I just get use to it. I don't know why anyone would want to adjust the primary to less tension than spec.

My '97 Buell (1200), 17k miles, just started making a similar tranny noise. It had never done it before about a week ago. It's also only when decelerating in gear off the throttle, a whining noise, and it comes and goes going on and off during each instance. I changed the primary oil and checked the chain tension, it seems ok. It worries me because it just now started doing it. And it's really annoying.

Think this is the same somewhat common noise, or something bigger and more serious?

Any help would be much appreciated!

I do the work on it myself. I recently changed the motor oil and the tranny oil, and it didn't help the noise. I checked the Primary chain tension and it looked within spec. I also loosened it a bit and it still made the same noise.

When I started taking it apart yesterday I noticed that the little spring inside the clutch adjustment cover was broken. I don't know if this could be causing the noise, but I had to order the part. I'll put it back in when I get it and see if it helps. If not, I'll keep taking the tranny apart.

The tranny doesn't whine in 5th gear because it is one to one on the ratio. I have a 1969 Z/28 Camaro with the M22 "Rock Crusher" 4 speed tranny. The reason it's called the rock crusher is because of the whine it makes in 1st thru 3rd gears, this is caused by the straight cut on the gear set. The straight cut on the gears cause it whine loudly but also increase their strength. The M22 does not whine at all in 4th gear because it is a 1:1 ratio and I bet that is the reason your bike does not whine in 5th gear.

So bgjjr and Cuban Sporty Rider, when your riding and you let off the gas in gears 2, 3, or 4, with the bike in gear and the clutch disengaged, you don't hear any high pitched whining sound (sounds kinda like a jet engine winding down)?


I'm starting to wonder if it's unique to the 1200's.

well about 100 bucks later and 3 new bearings the noise is gone.
I believe it was 1 of the needle bearings as on inspecting them 1 just diddnt seem to be as smooth as the other one.
the trans mainshaft slides thru the 5th gear and rides on the needle bearings and turns at a different speed when in any gear but 5th if this makes sense..

Just my 2c...

The first time I removed the derby cover on a Sportster I did it on the side stand and, of course, some of the trans oil promptly leaked onto the floor, perhaps half a cupful. It didn't seem much and as I had no trans oil I just left it.

Then I noticed that the engine was whining on decel. I didn't think much to this as the bike was new to me and I wasn't used to its ways.

A bit later I picked up some trans oil and filled to the correct level (bottom of the crinkly round clutch spring thing). The whine disappeared straight away.

I have recently aquirred a rebuilt 1995 1200XL Sportster put about 3k on it and suddenly I'm gettin a badass whine. the bike was a total strip only had 10k on it when I got it and only 100 of those miles in the last four years. Ran smooth as silk now the analogy of the turbine winding down is totally accurate did a full maintenance on it new plugs oil filter and drained the primary refilled direct to Harley specs and adjusted the chain for good measure no change. I am goddamn perplexed any advice would be appreciated

I see it's your first post, so,,,,,Welcome to the XL Forum!

That is perplexing that it started suddenly. Mine's done it since day one. I'm thinking of using RedLine gear oil in the primary next time I change the fluid to see if that helps. Amsoil quieted it somewhat, but with the Harley Sport-Trans fluid it was LOUD!

Perhaps some of the guys with solidmounts could chime in if they've had this issue?

Make sure your primary chain isn't adjusted too tight.

Just a quick question..... not trying to hijack the thread but what kind of sounds do you get if its too loose?? I changed my primary oil the other day and now I have a weird sound from my primary. It kinda sounds like something is rubbing or kind of a grinding sound..... but when I am in the throttle..... no sound. Ok back to your regularly scheduled thread!!:doh

A really loose chain can make a metalic chinking sound from the chain hitting on the case. It's easy enough to check the adjustment. Check it when hot.

Your discription sounds more like your engine sprocket nut is coming loose, and rubbing on the primary case.

The sudden sound rising up was the part that perplexed me as well. But It seems I may have a totally different direction to look in. Talking with some good ol boys about the 1200 turns out some of them tend to develop an issue with the starter armature not recovering completely or tending to slack forward this causes high pitch whines due to it riding on the ring gear...I am not positive this is the cause but I plan to appropriate a primary cover gasket and checking the clearance. I will let you all know what I find :sporty:

Question, when you are hearing this whining, is you gf on the the back of the bike?

Hello all I was out of town a couple of days and finaly got to dig into my primary case yesterday. Seems the problem with mine was an crappy aftermarket tentioner. It had been knocked off kilter pressing one corner of it into the case seems as though running it for the period of time i have had it about 3k miles or so finaly dug some deep grooves in it causing it to try and track the primary chain off at an angle 22 bucks from my local harley dealer the OEM part was much beefier and didnt flop around like the old one adjusted the clutch and the chain tention made about a 200 mile run not a bit of noise out of it.

Hmm. Ive had my XL for 5 years. It is a 1999 1200. It has ran great for 5 years, no whining at all. Today it started and It started bad! first thru fourth gear is a terrible whining noise and nothing in fifth gear. So i went to my manual. It must be something in the countershaft of the trans. 1 thru 4 all put engine power thru the countershaft but 5th gear is the only gear that goes thru the mainshaft only. i will be tearing my down soon. i will post what i find.

So I got my new 2005 1200C (6,000mi)all legal now and been doing some cruising it sure makes the spooling down whine off throttle and stops if the clutch is pulled.

So reading the posts sounds like the straight cut gears are to blame?

Also as others have said no whining off throttle in 5th.

so the 2005 was the last year of the straight cut gears.

Yes, that's correct.

if your tranny wines, could be clearance issues. hd basically says if it fits, shove it out the door. this was more so true on the older machines as hd tightened up their act but that dosen't mean they turn out perfect trannies all the time. most all the trannies that i worked on were way out of factory spec and when shimmed and fitted properly did not wine or shift harshly. being yours is without trap door, try different lubes as it may or may not help.

Cool that this thread is still going on.... Looks like about half of the sportsters whine in gears 1-4, but not in 5. I wonder if this poll is scientific yet? lol

I suspect not, because those whose transmissions do whine are far more likely than to vote than those that don't.

The new 6 speeds installed 07 and on have a terrible whine in 1st and 5th but i was told that was the cut of the gears. I have an 07 Deuce to go with my 69 XLCH.

So why doesn't it happen in 5th gear????:geek

2013 Sportster service manual - page 5-28 figure 5-44 Transmission power flow-

Looking at the service manual transmission power flow chart there doesn't appear to be any of the "gears" engaged when in 5th. The power flows straight through the shaft with the belt sprocket on it.

Of course the gears are always engaged (it is a constant mesh transmission) but you would not get a deceleration load on them when in 5th like you would if you were in gear 1-4 with the power flowing through the gears engaged with the shifter dogs.

I'm using Harley Formula+ in the primary. Syn3 is too thin.

Isn't SYN3 about the same viscosity as Formula plus?

Yes! That 5th gear on the six-speed twin cams is quite noisy, again, I've been told, due to the cut of the gears.

The new MoCo 6 speed has a straight cut 1st and 5th gear thats why the noise is greater in 5th

Yes! I understand that 1st and 5th gear in the six speed have straight cut gears. No big deal for sure as that six speed sure is nice when you're running 3,000 rpm at 80 mph in 6th! The thing is just loafing along!

The new OD6 is certainly a pleasure at highway speeds..and a lot of fun around town too!
