I recently bought a 1986 Yamaha YZ250 off of a friend of mine, and he threw in a 1991 Suzuki RM 125 as well! The Suzuki RM125 looks to be in decent shape chassis-wise, but the engine is locked up. I have started taking it apart, to see what it needs.

It will at least be needing a crank and/or lower end. I haven't split the cases yet, but even after taking out the clutch and other components, the crank won't turn. The threads on the flywheel side of the crank are messed up too. Does anyone have a crank and/or lower end that will fit this bike? What years will work?

I am also looking for plastic that will fit this bike, as all of the plastic that came with it was painted black by the owner before my friend. Long sigh. Does anyone have any old used plastic lying around that will fit this bike? What year plastic will work on this bike?

Lastly, can anyone tell me how this bike was back in the day?

I used sodablaster to remove paint from plastic, but it is dusty..

Ben990 - I do have a full set of used OEM plastics (minus fuel tank) for a 92 RM125 & RM250 that I can sell if you are in need. All in pretty good condition with original decals still in place. I am keeping a full set and have replaced both bikes with new plastics.
