    Hi I was wondering if lightening the flywheel would provide more performance? It would be quite an easy mod.

    Would there be a bolt on replacement from say a 510?

    Flywheel mass is there to smooth out the power delivery between power strokes. You might end up with a bike that won't idle and beats up the clutch basket and transmission.

    I took a lot off of mine, combined with other things that I've done, it snaps HARD.

    No.
