A few idea's I've been thinking about. #1 is the crankshaft heavier in the IT465 motor? The crankshaft in the IT490 looks a lot heavier, but I can't tell with the IT465. #2 has anyone here installed a crankshaft from an IT465/490, and did it work? If I could just slow the power band hit a little, I think it would help a lot. Right now when it hits, it's instant wheel spinning, fun, but not very useful.
Any other idea's on how to smooth out the power band would be good too.
