I just bought a 93 XR200 with a blown top end and need advice. The piston seized and the rod pulled the bottom of the piston off and broke a hunk of the barrel below the case. The crank seems good except for the rod, I will need a new cyclinder,rod,piston and valves. I will need to split the cases to get to the crank. Any good manuals out their for this? Where is the best place to get parts? I was thinking of Powroll's crank,cam,and piston kit to make it a 218cc. Any advice would be helpful.
