I ride an 02 YZ426F and generally ride mx tracks with it (never raced but just like riding fast on mx tracks) but I plan on doing some gncc racing this summer. If I add a 12oz flywheel weight how will it effect it on an mx track. I already have the weight but haven't had it put on yet. I did some tight woods riding this last summer and it sucked because I never seemed to get out of 1st gear and the throttle was way to abrupt for the woods. I was told that adding the weight would smooth out the power but I am concerned about how it will do on a mx track with the weight.
