I recently bought a used 2007 sportsman 500 ho efi from a faimly member. It wasn't taken care of the best so im going through the whole thing cleaning and fixing any issues. When trying to take the oil plug out of the plastic tank the metal insert that the plug threads into has stripped and now spins freely with the plug. Any ideas how to get the plug out and is there any fix? My assumptions is there arent any except by a new a tank. Which brings me to my main question. Am I stuck buying another cheap expensive plastic one or is the older style cast aluminum tanks found on older sportsman models compatible?
