I have an 08 all stock Teryx that recently just seemed to have lost a lot of power. It sounded like it was only running on one cylinder so I started checking for spark. While it was idling I pulled the back spark plug wire off and the engine died immediately. Started it back up and did the same thing with the front plug wire and it kept running. I switched the spark plug/coil wire from the front to the back and I got the same results so it appears I'm only getting spark to the back plug. Does anyone know what the voltage should be to the spark plug/coil wire? I noticed what I assume is the coil has a positive and negative sign. Also I was looking at a parts list from Kawasakipartsnation.com and it looks like there is a part called an igniter, part # 21119-0092 and was wondering is this what feeds the power to the coils? and if so could that be the problem?
