I have a 99 250 EXC. The bike has a Gnarley pipe with a power core II siliencer and a Delta Reed Valve. The jetting is right on the money. I 've tried several needles both straight taper and multi taper. I'm currently running a 3EMJ needle which I liked the most. The CEK/CEJ were to sluggish. I'm looking to get a a smoother power delivery so my question is has anyone out there put a flywheel weight on their bike and if so what weight was it and what were the results? I'm a 40+ B rider and I ride and race alot of tight trails. My thoughts are that maybe I would benifit in the tight stuff with a flywheel weight.
Thanks Mike
