I have a 2000 400EX that i plan to race locally, but not as a career. I live in Alaska so when we are not at the track we do alot of woods riding. I have a stage 2 K&N jet kit and filter, Big Gun full race exhaust, and +2 Arms. I weigh about 235-240 so i am not alittle guy. It gets out of its own way pretty good right now, but i need more. Any assistance would be great.

if you like please send inputs to rntdfrd@yahoo.com

Thanks, Aaron
