how do u make this model more powerful

 

I'm looking for the same thing. I was told here before that a gearing change would help. Stock sprocket in the rear is 40. Which way would I go (bigger or smaller) to get a little more power out of her? Front is 11T. Is it worth changing that one?

 

what i already did was get a bigger air intake, and bigger jets in the caurberator

 

and im not sure bigger or smaller

 

The power is there you just need to tune the clutch in.My 330 Trailboss will rock and even get a wheelie after doning some clutch work
