I got out riding with my buddy who has a 05 that is stock short of a marks pipe. We switched bikes at one point to compare, and wow it was sure a difference. I pulled out onto a sweeping corner and when I grabbed second and craked on it, the back end got all kinds of loose. I finally got enough miles on it to really pound on it, and wow the top end power is unreal. it takes no time to go from 60 to 140. I have a bit more tuning to do on the carbs yet, but once thats done we should be all set. I lhe love the looks I get when I pull the front end off the ground on this beast.
