Does anyone know if there is a difference in flywheels.between 77 and 1980 Srx.I have a 1980 bottom end and was wondering if there is a weight difference between years and what will work thanks for any input.

you can remove the extra flyweight off the 80 and it will be about the same. or just use the 77 one.
