Hi guys was riding my 08 700 on the track and everything was fine but all the sudden the engine just quit running. All the lights and everything comes on and the starter turns over but it wont start. I changed the spark plug and it does the same thing. Would it be the rectifier maybe? It has a pc5 but the map is the the exact corresponding mods! I want to get back on the dirt!! Help would be greatly apretiated!
