[ExVillin400]

well i want to get the t-4 slip-on. and ill have it the middle of august sometime. 2 people i know have the t-4 slip-on with a k&n with no jets and they say it runs great.should i rejet a little bit or would there really be no difference. if i do what size jet would you guys say, and would i have to adjust my needle too???

when i jetted mine (4ooex) i went to the dyno specs, but was way to rich so somewhere between stock and th dyno kit specs. i ride mostly under 3000ft

When i got my T-4, I put in a 158 main, 40 pilot, and left he needle in the 3rd position from top, and did not adjust the pilot screw, and what a difference, the thing runs like a top. You will notice a big difference and be very happy with your purchase!

take the extra time to properly jet your quad, then when you have the power advantage on your friends just grin :D
