1990 xr100, I cant find my manual, Im rebuilding the top end...
Which piston ring goes on top? And in which direction are the rings installed? The iron ring has an "n" on it on one side and the other is slightly angled.
What is the proper torque for the head studs?
With the piston at TDC, the "o" on the cam sprocket should be at 12 oclock right? Is there any way to get this exactly right? It seems like its too easy to throw the timing off by a tooth or two in either direction by just eyeballing it.
thanks
