Has anyone tried this product on any Yamaha 4-strokes and is it worth 90 mula u.s. From Neil way up in upstate N.Y. REMEMBER WERE ALL DIRT BIKERS SO WERE ALL BROTHERS AND SISTERS

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.

i really hate my bike, i can only go 80 km an hour, it has bareley any torque, it is an all around shitty bike and it is a 200 four stroke. if any one out there has any idea of how to make my bike faster and give it better torque without spending lots of money, please tell me. I'm out of ideas. PLEASE PLEASE PLEASE HELP ME. any idea helps
