I have a 2000 banshee, its is completly stock and allways ran great. Last year when I pulled it out after winter it was only running on one carb. so I pulled off the carbs. and cleaned them out. Then it ran on both carbs but leaked gas out of the overflows so I replaced the fuel valve assemblys and that fixed the leak problem. But the motor started breaking up under high throttle, I replaced the spark plugs, cleaned the air filter, emptied the exaust pipes of oil, changed the oil, and rechecked the carbs. The throttle pins open at the same time, and I cant find nothing wrong. I have a shop manual and did all work per it. The bike ran fine when put away for winter and had periodic starts during winter. The bike didnt run long on one carb so I dont think any damage was done there. The bike runs good except at open throttle and Im out of ideas. The motor breaks up and loses power when wide open. Any help would be appreciated. Fellow banshee lover.
