if you dont have enough money to ge ta better pipe than the cobra, then at least get an oversize header, deffenitly fix the jetting, get sdome nerfs and get rid of that plastic hanle bar cover and replace it with an over size bar pad

the main jet is 122. Just call someone who has dynojet jet kits and get that. Its $50 which is good where I live because my dealer charges 5.99 a jet. It comes with 8 main jets a new needle and the main jet adaptor. I got mine from www.freeridepowersports.com. Call him. His name is Chris and he works some deals. I got three sets of brakes plus my dyno jet kit for 90 shipped.

When i did my engine mods I never had to jet. the plug color just changed a Bit, I run a 126 MJ, no lid and no choke and its perfect. I have plenty inside also but thats top secret.
