Ok this is a new thread, but I posted an old thread a few months back, i will link it, and the ones that recognize the thread, that is me. UPDATE: Okay so I got a new carb (well used carb that I rebuilt) and got a new pilot screw, turned it two turns out, got a new stator, it starts up IMMEDIATELY!! I installed an Oil Cooler Mod with the Hayden 401 Transmission cooler, and couple of Fragola 90 degree -6an swivel fittings, yadda yadda so on, so forth. I put 3.3 Quarts of Valvoline Racing 20w50 oil in it. The clutch seemed to be slipping (it was sitting for 8 months (or more) doing nothing). Once it got warm and the clutch got wet (hehe sounds dirty) it seemed to shift fine, so everything is good in that department. Here is my question... I took the Stock Airbox off of it. I built an aluminum housing that holds my electronics and battery (some cutting of the plastics was done) and I'm running straight UNI Carb Filter and crankcase breather. It seems to be running lean at the current moment, do I need to re-jet the quad? Has anyone removed their stock airbox and run straight filter? If so what jet kit did you use? OR did you just adjust the pilot screw out (or in) to compensate for the lean fuel mixture? One other thing, my Haynes Warrior manual is right next to me, I'm just to lazy to hunt down the illusive instructions as to the correct way to turn the pilot screw in order to make it more rich/lean, does anyone know which is which?
