I've got a 1988 Harley Sportster XLH 1200. I'm getting gas in the oil. I thought it might be the piston rings but it has plenty of compression. It starts very easy. I was told that it could be the carburator. I can't see anything wrong with it but I'm not sure how to really know for sure. It's a rev-tech carb. Could it be as simple as the carburator or is it something more serious (i.e. valves, piston rings, or carburator)? My email is [email protected]
