The next drag that Im entering is on August 7th. I have to be in the 0-450cc Improved class. I'm looking to do one more thing to my bike before the race. Give me some ideas, I've read that putting a 450 carb might help. Right now my 400ex is piped, jetted, stage one hot cam, 13 tooth front sprocket, Razr 2 tires, lower to the dround, and I have the air box lid removed. I'm willing to spend some money before the 7th but not to to much. I go to back to college at the end of august. Thanxz.
