Why are 2003 XCSP 600's so fast?!?!?!? I don't understand... it's stock... my buddy smokes like everything he goes agenst, firecat 600's, and other 600 and 700's. The only thing he can not beat is a 04 XCSP 600 thats also stock too and he only beats him by like a ski length. What is the stock hp for the 03 xcsp 600 and why are these sleds so darn fast for stock? My buddy also has a stock 1 inch track...
