Default 2005 bruteforce 750i backfiring through rear carb.

No matter if it is cold or warm. very hard to startup. It sat for 14 months.
I cleaned the carbs, drained the fuel,refilled with fresh fuel. had to use carb cleaner to get it to fire up. fuel delivery is fine. fresh plugs installed. backfires through the rpm range when accelerating.

Any ideas. Im trying to go riding saturday. I know it was a mistake to let it sit that long with fuel in it. but when I cleaned the carbs, there wasn't any clogs.
