So I have a 1998 grizz 600 that backfires through the carb. Cleaned the carb and glanced at the exhaust valves and everything’s in spec. Pops no matter where in the throttle you are. It’s a random pop and engine sounds perfect otherwise and starts great. Always had random popping but now it’s unrideable and never did anything to it just cleaned carb after it became unrideable and still nothing. Any ideas?
