pop a 13t front sproket on there. itll accelerate a lot faster but youll lose a little top end. if you can deal with a 4 mph loss in speed its a great upgrade for more usable power.

I have the 13 tooth upgrade. Add a curtis sparks pipe and a pro flow kit and it will put a smile on your face again.

JT 13tooth front sprocket is what i JUST put on my kfx and you really notice bottom end of the gear and 1st and 2nd. definetly gets up to speed faster. get out the hole alot quicker as well. cheap and easy to install mod... $24.00 on ebay and took me 2 min to install
