Are the torque values correct in Club Year Book ?


Well they quote 7 ft/lb for the cam cap bolts on all models which is in line with what the guys are saying here, so I would believe the Yearbook rather than the Shop Manual in this.

I think there may be a typo in the "Cylinder Compression" figures for the Z1,A,B,Z900 though. It quotes "30-155psi" ! I think if you're at the lower end of that you might be looking for a new head or pistons :D

90% of questions that begin "Why..." can be answered with "Because people are stupid."
