I was adjusting my chain tension the other day when I noticed that my oil level appeared to be completely overfilled in the sight glass. The last time I checked my oil level was about a month ago when I changed my brake pads. The oil level was in the middle of the window at that point (roughly 800 miles ago). When I opened the fill plug, the crankcase reeked of gasoline. What could be the cause of oil dilution like this? Lately, I have noticed that the bike has been running fairly rich and it has been backfiring more often during engine braking. My fuel economy also sucks and seems to be getting worse. I have read that injectors can become gummed up and stick open, causing gas to leak down into the cylinders while there is residual fuel pressure. Has anyone else on here had this problem? 2005 SV650S with ~28,000 miles TIA.
