Hello, I am having some problems with my 2003 F5. It started to run bad and backfire at low RPMS, but once up to speed it ran fine. I cleaned the carbs and drove it again and the same thing. It kinda seemed that the power valves were hangine up, so i rotated the servo motor to take the tension off of the APV cables and found that the servo had stopped with the power valve open up just a bit and had been holding the valves open. After i rotated the servo so the valves were closed I drove it and it seemed like a new sled. It had power from the start and it didnt backfire anymore. Now ever since then when I start it the servo motor cycles 3 times but it cycles in the opposite way it would move to open the valves up, and usually stops in a different spot every time. Just looking for some helpful information, since i dont know anyting about Arctic Cats APV system.
