Cam Chain Guide Replacement - Help

Is it possible to remove and replace the cam chain guides without cylinder removal? I dont have a manual, but from the looks of the parts breakdown on a fiche it appears that the cylinder would need to be removed.

Anyone know for sure?

Please do not remove your cylinder! The chain goes in great through the mag side. You will need a flywheel extractor / puller and a Torx set. It helps if you unbolt the right chain buffer also and push it up out of the way.

Please work patiently.

Take care.

I'm not sure that the bracket that secures the rear guide will fit through the cam chain hole in the barrel. I know you need to take the head and the flywheel/stator off (the latter is secured w/ metric torx fasteners BTW) …

I can’t remember exactly how it comes apart, but I don’t see why you couldn’t change all those parts out with the barrel on the bike (and the piston staying in the barrel).

Getting the front guide out can be tricky, it sits in a groove in the cases, and if the motor is still in the chassis things are a little tight, but if you lift the head up about an inch, then stick your fingers in the space between head and barrel and lift the guide out of its groove, then turn it clockwise 90 degrees it will come out through the cam chain passage in the head. Then the head will come off easily, then I guess you will find out if the rear guide will come through the barrel :)

Sorry I couldn’t answer your question definitively, but I hope this helps.

How'd you get the front guide out without lifting the head??

Inquiring minds want to know :)

If not, then I want to know. Looked impossible to me at the time...

I've pulled my front chain guide without removing cylinder. DOn't know about back one.

Sorry for the spelling Hick. Always in a hurry at work, no computer at home ( like it that way! )

I basically removed valve cover, tensioner , cams, mag with pick-up, that back plate of sorts with the Torx screws and unbolted the buffer/ guide that runs against the tensioner. I don't remember lifting the other buffer out ( the one that more or less snaps in place ) I just kind of liften the bolt down one out of the way. It has a cupped shaped metal end that was troublesome.

Was then able to spin the chain on carefully using the kick start by hand.

This was last year, my aging mind may have forgotten details but the head stayed put.

Hope this helps.

And oh yeah, I posted and both you and Boit said it was doable before I tried.

The original question was about getting the buffers out, not the chain. The front buffer that “snaps in place” is the one that I think won’t come out with the head on, and the “cupped shaped metal end” is what I’m worried about as far as clearing the cam chain hole in the barrel.

Heck R6, you may be able to get everything out with the head still on. Remove the flywheel and stator and see if you can’t somehow coax the front guide up and out of the notch it sits in. Taking the chain off first may help this, and you probably can’t get the steel bracket holding the rear guide out with the chain still on the crank.

Anyway, I hope you find some of our posts here helpful.
