I am rebuilding my 96xp and am not sure how to go about selecting the right piston size for the new setup. Can someone help? Thanks
 
if you can clean the top of old piston enough. it'll say the size, otherwise, depend'n if jugs get honed/bored, then machine shop will "mice" the walls, and let ya know....:cheers:
 
I was able to clean the top of the piston to see that it is a std. 82mm. The reason I am rebuilding is because my compression was hitting only about 125psi in both cylinders. The cylinder sleeve looks like it is in very good shape. Do you think I can install a new piston kit of the same size and regain the missing compression? Thanks for your help on this!
