What quad? What size tires?
What are you looking for, top speed? Torque?

400ex
i wuz want good top speed and still have torque to
hm i think tire size 20 or 22 i ain't sure i would have to look at the tires
i try to ride a lil bit of both types of riden

If they are stock tires they are 20"

It is mostly personal preference on gearing choices.

There is direct trade off when changing gearing.... Gain top speed = less torque. Want low end torque you lose top speed. You just to figure out what is more important.

For me the stock gearing is just fine for general riding.

so would a 38 tooth be good then cuz that is stocl

You can go up 1 tooth on the front for more top end speed, less low end power or down one tooth for more low end power, less top speed.
Rule of thumb: 1 tooth change on the front is equal to 2-3 teeth change on the rear.

go 36 rear 15 front


i run that gear and then a stock motor with a sparks timming advance key pulls great

I would stick with the stock gearing but its all about personal preference..;)
