General 126 Crankshaft

Hi
Can anyone tell me if the 126 crank (used in 650 engine) is the same as a 500? and which model (F,L or R)

Thanks

The cranks are all the same and interchangeable. The Bis crank from the 704ccs water cooled engines is slightly different but will still fit an aircooled motor.
