HMF Swamp XL exhaust

[Jmathey9]

For: Anyone that can help

I have a 2011 sportsman 500 ho. I put a hmf swamp xl exhaust on it so I had to jet it as well. The recommend jet settings were way too rich and I kept fouling plugs. I took it to the local Polaris dealership and went riding. It was a little better, but fouled more plugs. Took it back to the dealership and had them do it again. Now it seems that I am really close. I was pulling my kids on their sled and I started to get the tell tale signs of fouling plugs. I dropped the sled and rode it hard for a few minutes and it seems to burn off the carbon and run ok again. I can't always ride this thing wide open so I need to do something. I have already spent way too much having someone else mess with it so I am on my own now. I can do the work myself, just have little time to do it. I know I am running rich, I can smell the gas in the exhaust. What's your take on it. I am to the point where I going to just go back to stock pipe and settings so I have a reliable machine instead of dealing with changing plugs on the trail. If I would had know that a slip on exhaust and k&n filter were going to be this much work I would have left it alone, but know I am hundreds of dollars in so I kinda want to get it there.
