Just purchase a 1995 XR 600. New to ThumperTalk. Want some advice. How should my carb be set up? Bike contains K&N filter, Husky exhaust?(thumps low, loud reved), 13t front sprocket 48t rear. Otherwise bike is stock. Ride between 5000 and 10000 ft. I ride trails in 1st thru 3rd. Your help is appreciated P.S. The bike hesitates sometimes in 1st when you get on it.
