I need some help, I have broken three stock baffles and yesterday a Vortip insert. Do I have a problem with jetting or somthing else? The bike is stock, the jetting is stock, the airbox has not been altered, the timing is WR standard, and I have not done any of the mods suggested on this board. I ride at elevations of 2000' to 4000'. Any help or ideas would be appreciated. Thanks.
