Re: doing valve shims

i may just drop the engine out looks like a right faff with it in
i need to do the cam chain (i think anyway) so may be easier out of the bike

Re: doing valve shims
Its dooable in the frame, just more akward, and if you have to change the cam chain too ,then yes, drop it out.

Re: doing valve shims
the reason for doing the cam chain is i dont know if its been changed and as the motor is reading 25k (how accurate ?) i prefer to be safe than sorry
someone has already been inside the engine as i have some hoymalar around the sump gasket and the timing casing was sealed with white silicone

Re: doing valve shims
you cant adjust the rockers hence you change the shims
having dropped my engine to do the timing chain and check the shims i personally wouldnt want to check and change them with the engine in the frame
having said that there are a few posts on here with people having done it all with the engine in the frame but it is fiddley as per posts
good luck in your quest

Re: doing valve shims
you should measure the 20 link length of the cam chain, i forget the length but its in the manual. If it exceeds it, then it needs to be changed. But for the sake of 20/25 quid and while you have the engine out you could just change it anyway, i would.
