i need to replace my piston.
how do i know if my piston is oversized? there are a series of numbers and letters but i cant find how they correspond with any information .
should i measure my bore w calipers to make sure its in spec?
what is this spec?
where can i find a manual?
where should i buy a gasket set?

on ebay, the only manuals available are owners manuals and clymers which covers 81-88 which im afraid wont be as detailed as i need it to be.
i need to know how to adjust the power valve.
