Alright I finally got a Yoshimura slip on for 125 bucks and its like new. (Have to save Money Gettin Married) Anyway I need some help with the jetting. I want to drill some holes in the airbox lid and Im not sure what size to drill or what size jets to use. Im at sea level and have a pro design foam filter with clamp. THe quad is a 05 and thats pretty much it. Im mechanically able, but I need your help with what to do. Please help I just dont wanna screw it up. I appreciate any help. Oh what kind of jets should I use and should I buy a whole kit. Thanks again. RYan
