in the sand, take it down one sprocket, if normal dirt, might be good with the stock sprocket.

 

It also matters about your weight.

 

im 6' and 145 pounds

 

In a flat sand drag my friends piped ex was faster with the stock setup than with 1 tooth smaller in the front.

 

he should have higher stop speed but slower accelration but i went up 2 teeths in the front and liek 4 in hte back
