crf100 inner rotor

has anyone put an inner rotor kit on a crf100 and does it really make that much improvement for the money?

have the flywheel turned down first. that will give you an idea of what it will feel like. i personally love my lightened flywheel but still wouldnt drop the $ on the irk.

how much did you have taken off?

haha a lot, 16oz's. it deff revs quicket than before, btw mine is an older points ignition flywheel not the newer one. not sure if u can take that much off a newer one or not. i got lucky too, no vibs even with no rebalance.

dang that should make it rev quick. ill have to try it out.
