My grandfather had a 08 prowler 650 that he stopped using and now he's letting me use it. It still doesn't get used very often but I plow with it. I usually go out and start it and let it run for a little while once a week. Recently it didnt wan't to start. Seemed like it was getting too much air. I took off the air filter housing cover and saw one, that the air filter was a replacement k&n and it doesn't fit right at all? Could anyone give me part numbers for filters, doesn't have to be k&n. I put my hand in front of the air tube on the front of the housing, cutting off a good amount of the air, and tried starting it, started right up and I took my hand away and it ran absolutely normal. So any ideas on this problem and possible solution.
