i have cleaned the jets on this quad twice , it runs rough all the way up to mid range. this quad has sit for periods of time, it has new gas in it, i took a pre charger off the air filter it ran good for about a minute and then started up again ????? what could it be

[dirtrider77]

your jetting could be off...i beleive the pilot and main jet control up to 1/2 throttle, but im not exactly sure, some one will chime in though...but sounds like ur jetting is off

and by the way, im also from ky...names james malone

lol...kinda funny

Sounds like your pilot jet

[jeff malone]

I never changed any of the jetting, it used to be right. could it be some passage ways that might be clogged

[wckedclownz69]

yes some could take some cleaner and spray your pilot jet and pull your main jet and shoot some up the little hole and make sure your air/fuel screw is right..
