Hello! Please help. My bike is year 2000 and it won't start. I have a power commander 3 and sato pipes. I took out the commander still wont start, so i put it back in. I have a new battery. I also put new plugs and coils to see if that'll work.. it doesn't. Any suggestions??? I took it on a 1 hr 20 min ride. It was great, felt healthy and it sat for 2 days now I'm here. It has gas, new spark plugs, coils and battery. What's next? It also backfires and shoots a flame.
