So I have been through **** and back with this grizzly. I finally just got figured out why I was burning through spark plugs and it ran great was a bit stubborn sometimes starting but nothing major as I am in Ohio. I went to back it out of the garage the other day and it started I had it choked took the choke off backed out out it stalled so I left it sit. Later went to just put it back in it would barely start when it did it ran like crap spitting sputtering backfiring then died like it was choking for gas I just filled it up the day before with non ethanol fuel so it wasn't out of gas. The carb was just cleaned when it was in the shop less than a month ago so it shouldn't be gummed up. I'm at a loss with this thing. Any ideas?

May be worth checking fuel flow from the tank, air filter, stuck float? Plug, plug wire, and spark, just spitballing here, a lot of owners like me have had wiring harness issues. Right side under seat, harness wiring.

I think my mechanic and I have narrowed it down to being the top end again not sure exactly what but ever since I had the top end redone I have burned through spark plugs or doesn't matter what we do I still burn up the spark plug after about 5-7 times riding it here and there not even trail riding just around the house this last time he was sure he got it he assisted the meeting in the carb signs pointed to getting to much fuel I rode a hand full of times and now I'm back to square one and the spark plug is burnt up again black as can be in at a loss with this thing

Man, that’s frustrating, I wish I had a good suggestion. Hope you can figure it out.

Spark plug is burning up or fouling? Post a photo of the bad plug.
