So bike starts fine and seems to be okay until it warms up then it won't idle. Basically if it's sitting under 3k rpm it will stall. I've cleaned the carbs, turned the air fuel mixture screws out 2 1/2 turns, cleaned the air box, replaced the fuel filter, and I'm getting good fuel flow. I pulled the spark plugs and saw that it's for sure running rich. I checked the float height and it seemed to be good. I'm thinking float valves need to be replaced. Any other ideas?
