I'm down for a ride...let me know man. I've got a buddy with a 440, hot cam, curtis sparks pipe, high comp piston...and to be completely honest, they're fun as hell to wheelie on, but that was the only fun I had on it. If you think doing wheelies is going fast, a 400ex isn't too bad of a choice. But the shee ABSOLUTELY DESTROYS the 440.
By the way, I just bought some Pro Circuits Platinums w/silencers off of HQ for $260.00 shipped to my door and they're damn close to brand new. The deals are out there, just gotta look.
