1980's RM 80 ---Are all the early RM 80's the same design?

[riatvriderwd]

just recently bought an rm 80 for 50 bucks--complete rolling chassis, bottem end of the engine and basically everything but the top end/carb/exhaust and probably needs a new clutch. What im wondering is:
1. Were all the early model (even later models?) are they the same engines and chassis designs?
2. Is this bike liquid cooled?
3 Does anyobdy know where i can find some parts cheap for this?

thank you very much

80-82 were aircooled 83+ were liquid cooled. Pretty much every bike ever produced for any extended period of time most likely has engine and frame tweek's and completely new designs. What year exactly is your bike?
