Trying to figure out what is going on with my banshee. Starts no problem, runs fine, but when you open it up it kind of surges and won't open up all the way without some surging. Its got a 76ho 4mil engine, port work, toomeys, etc. I know the previous owner said it is set rich as he dragged it and something with the floats causes the carbs to leak when the engine is not running, so have to turn the fuel off after riding it. I don't know a lot about the bike, but I ride it very easily. Think it could be fouled plugs or something else? For the kind of riding I do its not practical at all and thinking of trading it for a 4 stroke, but want to get this little bug worked out. Any suggestions appreciated.
