Ok, heres the deal. I have a 1987 XR80R that the piston rings where froze on the piston. So we take it down to the honda shop and one of the guys that works there knows us really well and we have helped each other out a lot...So he wants us to pay just for parts, and he'll work on it in betwen other bikes. No big deal But its taken over 4 months, 3 wrong sized pistons, and a lot of trips to the honda shop.... We are about to go over there and tell him we'll take the cylinder head off and bring it to him then. I was wondering if anyone knows where I can get the PDF manual for this bike? And ill have to take everything inside the motor out to put the new piston on the crankshaft right?
