wr 450 trim flywheel

Has anyone ever tried to trim metal off the fly wheel,so the revs pick up quicker,if so ,How much weight did you take off,I know a yz fly wheel is 1.5 lb I dont know how much the wr fly wheel weighs,any help out there?

It is easier to put in a YZ450 exhaust cam with better results. The bike will really go through the gears quicker and hit the rev limiter faster. Leave the flywheel alone! :cry:

Those flywheels are most likely balanced pretty well. I wouldn't touch it myself and i have access to a £20k balancing machine.
