what gearing should i use!

[Sporttrax400ex]

okay i got a stage 2 hot cam 11:1 high comp piston bernett clutches heavy duty valve springs ported and polished pro circuit full system k@n filter and im gettn a 39mm fcr carb prolly.

i like bottom end power but dont want to loose a whole lot off the top.

im gonna have 18" mx holeshots on the rear now instead of stock tires.

Try going up a tooth on the front or down two on the rear. If the comp is really what you think it is then it should pull either no problem.

It is a trial and error to see which combo matches the power spread of the engine and ride style of the rider best.
