Ya cant really mess around with the stock jetting but yeh i would recomend changing the jetting. Maby going up a few sizes on the main jet and a slightly larger pilot jet.

Do you plan on running with or with the lid on?
What kind of air filter are you running?
Do you have any other mtor mods done to your quad?
