I was thinking about putting a flywheelweight on my 04 CRF450. I ride mostly woods and I was going to go middle of the road in weight. What is that 9oz-13oz? I was running a 52T rear sprocket with no probs but I wanted a little higher gear range so I now have a 50T rear. Anyways in the really tight stuff obviously a lot more clutch is needed now and I am getting some rattle type lugging sounds down low but none before with the 52T (Just go faster, right) if I am not slipping the clutch while lugging. I was actually thinking about a rev-loc as a possibility but the flywhel weight seems the more economical approach. The question is will the weight take away a lot of the rough lugging sounds and smooth that out. I dont want to lose any of the instant giddyup that I have now though. Can someone describe in their experience what a weight addition (and how much it was) will do to this bike.
