2002 mxz 800 Little backfire on deceleration. Sleds runs great otherwise. So Put on 65 miles today, half way through my ride I noticed as I slowed and let off throttle from 4k + rpms I’d sometimes get a random backfire, just a little pop out of the exhaust. Also noticed the sled is really bad on gas, in that 65 miles I ate up almost a whole tank of fuel might have had another 10 miles left. Everythings been gone through Carbs and rave valves are clean. screw on carb is still at factory setting. How can I work this out any help would be much appreciated
