MZ Skorpion 660 motor. Just had the entire motor opened up and inspected. While we were in there I had the mechanic weld the crank, do a valve job, replace rings, valve springs, valve guild seals. Also threw in a stage one HOT CAM. So now instead of a spare motor of unknown condition, It is very much a known quantity. RPM has build multiple OMRRA number 1 plate superbikes, so my confidence in the mechanic is absolute. I'll be reassembling a Skorpion unless....
Does anyone have an MZ125 dirt bike they want to trade??? Could be the trail only model or the enduro or even the SM. But no RT.
