I recently bought a Pro circuit T-4 slip on, and a pro design k&n filter kit with flange and a Dyno Jetkit for my '03 Warrior, I havn't installed any of it yet because I was wondering how I should jet my carb and if any adjustment is needed on the carbs fuel/air mixture screw. Any suggestions????
Thanks

 

i'd put it all on, run it with a 150 main jet, and if it runs to rich go down to the 147.5 or 148, whichever they gave you.... and you just have to find the sweet spot for the air fuel mixture screw, it's ussually 2.5 to 3 turns out

 

The Dyno jet kit should have instructions.
