CAM 2 stuck

[malonek]

I can't seem to get CAM 2 out. Yes, they are aligned. It seems like it is stuck on the lobes or something.

OK... sounds silly but have ya got the top end off???


If it's still on then valve spring pressure will hold 'em in...

Completely torn down for a conversion.

[stevo]

OK......

dunno then as I've never had any probs getting any out....

Can't remember anything that would cause a problem but it's a few months since I've done one and I've been playin with mining equipment for the last few months.....

There is a sequence for removing them but I can't remember what it is while I'm lookin at the 'puter.... I know it as soon as I look at it tho.... :D You'll see that anyway 'cos the one that drives off the pinon gets in the way..

I'd say gently prise it out after you've removed the lifters..

[malonek]

It finally came out, guess it felt it wasn't it time.

Thanks for the response though.

As a side note: holy crap are the clearences tight in the case. Now I am worried when I get my new ones.

[stevo]

what cams are ya getting????

[malonek]

.256 I believe. If I ever get them from NRHS.

[stevo]

256???????



do ya mean 0.536????

a 2 series number is used on Twincams

Yep, I was close though..... :doh

Turbota's cam install post is a great help. I cleaned then bathed the new cams in motor oil and they slid right in. Good luck.

[stevo]

OK.. with 0.536's make sure ya check the exhaust valve to piston clearance..

Ya should do it anyway but they are a bit tighter than most in that area..

I have that problem right now, trying to remove them to install the new ones. number 2 is stuck to the cover, it rotates, but doesn't want to go out. the other ones came straight out

[bigbluebowtie]

You probably already know this so this may sound like a stupid question, did you take the ignition rotor off? If you did, I have no friggin clue. Sorry if this doesn't help...

Ignition rotor as the bolted on plate on the outside of the gearcase cover?
Nop, i really hope that's why. My service manual didn't say anything about it though. I knew there had to be something holding it back. What should i do with the bolts, use a drill or something? Are there threads on those bolts so i can use regular screws after i've pulled out the bolts?
They're andrews N4, I shouldn't get any issues with them?
stage 1, with n4 cams. haha, ill do more later though.
Lots of questions, but thanks :)

Ok, now i've removed the ignition rotor and the cam came out :doh
but nowi cant get the cam casing to fit onto the engine and the cams! the cams are installed in the engine and the casing should just slip onto the new cams? this blows!

[Torkil]

I've put the rest of the bike toghther, except the cam cover, the cams are in the engine. I cant see why, but do the pushrods have to be taken out when replacing the cover? need help :(

got the same problem as here, but no answer (http://xlforum.net/vbportal/forums/showthread.php?t=51240&highlight=replace+cam+cover)

Ok, everything went fine putting the bike together, but when im starting it, it runs really weird. first going on only 1 cylinder, then sending exhaust out the airfilter, and dies. i know the cams are aligned. could i have messed it up putting the worng pushrods in? switching exhaust/intake? i am not loking forward to tearing it apart for the 3. time!:doh :doh

Anyone got a clue?

exhaust out the carb would say that there's something wrong with the cam timing, doesnt it?

[Torkil]

Sometimes it manages to run for a few seconds, then a big backfire or exhaust out air filter. what sould i check?

camtiming, ignition timing, pushrods? HELP

[chrishajer]

Start with the timing, since that's the easiest. I doubt it, but what the heck.

After that, are you certain which way you installed the pushrods? Hard to recheck them now with the one piece tubes, but either the pushrods are in the wrong holes, or the cams are out of time. Sounds like the longer exhaust pushrods got installed in the intake position which holds the intake valve open and causes backfires out the carburetor. This is most common on the front cylinder.

HI! i tore it down, again:doh to see that the cams are correct. How do i tell if the timing is the correct, i installed it as it was.
to the pushrods, i installed the ones 3with red lines for exhaust, and the ones with 1brown line closest to the carb. i hope it was wrong:p

edit: i havent mixed up the pushrods between the cylinders.
checked, the longer ones are furhtest away from the carb, they are placed for the exhaust.

how could the timing be incorrect, i installed the ignition rotor as it was, marked it's position.

[Torkil]

Hello and thanks to everyone!
the problem was that i puttet the ignition rotor upside down:doh :doh

anyway. the bike needs jetting and fine tuning. at about 5000rpm+ it kicks ass! pulls like a real iron horse should do! hehe.
