Ok, I am rebuilding my RZ 350 motor from a box :baseball_bat: , I have some questions for you guys. I need a crank, the motor lost the oil pump and it atew the crank. The original owner (who taook the bike apart in 1984 with 290 miles) tossed the crank out, so i need a new crank. I looked into a replacement unit from the dealer but it was like $900. How are the ones on ebay? what stroker fits the stock cases and cylinders without machine work? I do not anticipate the engine reving ove 11k rpm all too often. any suggestions? the bike has the whole full on Toomey kit from new, pipes, carbs, cylinder porting.
