Flywheel weight

[boardadikt]

Has anyone here put a flywheel weight in their YZ450F? If you did, what size did you use and how did it change the way your bike felt? Was anyone able to add teeth to the rear sprocket? Thanks.

I added the 5oz factory flywheel weight. It helped alot with the stall but with stock gearing it took away the instant hit. I run one tooth smaller spocket on the front and it gave back the hit and is great for the woods. Only problem with that is it has no top speed for open straights. For open stuff i switch back to the 14 tooth front sprocket.
