this past weekend my quad is acting a little funny
jetting is 170 main stock not dynojet
4 clip down on needle(stock is 3rd or middle)
42 pilot
2.5 turns on airscrew
it pops slightly on decel but i think itsbecause there is a sligh leak where the header meets the pro meg
but know when i crack the throttl ein lower r's in hesitates and pops. wasn't doing it before. in mid to uppers its fine. only really happens if its more than 1/2 throttle it seems. my plug is PERFECTLY tan both times i checked. the insulator is tan all the way down. i have about 32.7 hours if i am correct on the hour meter(top end), about 75-100 on the whole quad.
i was thinking my carb is dirty maybe and a jet is clogged? or do i need a lager pilot like a 45, would this be caused by being rich or lean? no choke, stock head, no porting, just mods in sig
some holes in airbox lid
k and n
what should the air screw be set at?
i am going to pull the carb this weekend. since i wont be riding since it just snowed 20 inches were i ride at.
plus i need tires bad.
its about 30-40 degrees ot right now. i will prob go to a 165-168 main in the summer
