I have an MC21 SE/SP bottom end that I am parting out. PM me if you need anything. If you have an R-model and want to convert to the dryclutch, heres your chance. I will sell all the clutch parts and the tranny. If you wann save on shipping, I can send just the clutch parts and the main shaft only. Crank still has some life in it. Cases are good. Has water pump, oil pump and rotor and stator on it. There is a crack in the bottom of the plastic clutch cover. Parts are shipped from Japan. The entire bottom end will cost about $120-150 to ship by sea to the UK or US due to the weight.
