Hi All, I've got a 1981 SH XS, my cam chain adjuster pin pops out and back in when the pistons are rolling over top dead center. I read in a thread something about "it's when the b valve roll over and is normal" but this carn't be normal as the adjuster pin makes a loud knocking noise every revolution and watching the adjustment video the pin does'nt pop out at all.
I'm not sure if the cam chain is too long and this is happening because of the amount of slack in the chain. The tensioner is still holding pressure on the chain but because it is pushed in so far in that when at TDC the load the valves put on the cam straightens the chain on the adjuster and pops the adjustment pin out for the breif period.
With the adjuster removed how much slack should the chain have.
I've counted the links and there are 53.
I just got the bike and the previous owner had just replaced the chain and guides.
Cheers
