I have a 06 buell Ulysses and its was running fine then one day it just started running ruff and stalling. I replaced the spark plugs, wires, coil pack and the exgust actuator. Still the same problem and there is no check engine light. It also had a crack in the muffler which I just had welded back. I also drained and replaced the fuel and replaced both Pcv valve I think is what it's call the air valves for the head covers. It wants to start but it just chokes out every time. The bike only has 10000 miles so I'm not really sure what the problem would be. Any ideas.
