can't see the clutch lever on the generator side of the engine so its prob wr 200 cases, the 60mm crank hes talking about you can get from the states but takes some work to fit the dt generator side of the crank to it, its a stroker crank for a yamaha blaster quad which is the same engine as the wr/dt 200 except they blanked off the water pump and put a aircooled top end on it

no the tranferports on the crank case would need opening up also the stroke is 60mm and the 125 is 57mm stroke so the cylinder would need 1.5mm off the top and off the bottom or fit a yamaha blaster crank
