I have a couple in my group that has 2 05 summit x 800 revs and they both seem to foul plugs often. His wifes sled seems to be the worst at it, on a full day of riding she will go through 1 or 2 plugs. They run the BR9ECS plugs in there sleds. His is not near as bad but he said that he fouled a plug yesterday and wanted to know what could cause it. My guess is maybe the DPM is sticking? both got rebuilt last year so I don't think compression would be it. Altitude would be around 5000 to 8500 feet.
I thought maybe running a hotter plug might fix the problem but dont quite know? Let me know what you guys think could cause the plugs to foul way to often. Thanks guys
