Changing front sprockets on a raptor 350
I have an '05 raptor 350 with the GYT-R performance upgrade (air filter, rejetted carb, and exhaust) and I'm wanting to change the front sprocket. It comes stock with a 13/38 setup. Does anyone have any advice on which way to go on the front. All I know is that dropping to a 12 tooth front will give more torque and going to a 14 or 15 would increase my speed. Any suggestions?
