Just got my yoshi pipe for my 03 Raptor on and holy $hit ! This thing flies! But i feel now my gearing is a little low any suggestions which sprocket to change just to make first a little higher. I have stock setup witch i think is 13/40 is this right? Thanks for the help.

 

Bumping up one tooth on the front sprocket will raise your gearing, and give you more top end speed.

 

..........giving u less torque, i dont recommend it
