hey guys, if you go on www.denniskirk.com or rockymountain, you can purchase universal K@n filters from $20-$50 that clamp right onto the carburetor! I have heard you can see gains of 2HP with proper jetting! this will eliminate the crappy intake system that resides in the predator. i plan on ordering this ASAP, so hit me up in this thread if you have any questions. i might not be around tomorrow, but i get back to ya.
