I good choice is to drop the rear sprocket down to a 36 tooth or raise the front sprocket up to a 15 tooth. I did the 15 tooth front since I couldn't get a 36 rear when I did mine.
You do loose a little of the low end snap but not much. It does help a lot on the top end though.

Do you have the stock air filtter set up still . If so you will need to install a new air intake tube with a k&n air filter this bike will screem on top end. The stock intake will not let the kfx take in enought air. A power commander will be needed to set the fuel ratio. I sell the intake tube spacer for air filter & k&n air filter with all parts to in stall on bike.
