Yesterday I did a full oil change at 4,000 miles on my 2013. I replace the filter, the spring, and both o-rings while I was at it, and used Liqui Molly 4T 10W-40 motorcycle oil. When changing the oil, I noticed a bit of wetness on the bottom of the engine, but there was never a drop on my driveway, so I attributed it to possible spills from previous oil changes.
The bike sat overnight, and this morning when I got out I specifically looked on the driveway under the bike, everything was nice and dry, no drips, so I knew the oil change went well. Then I took a ride to the gym, and coming back I noticed a wet spot under the bike, maybe 2-3 square inches. I wasn't sure if it came from my bike or possibly from a car that was parked there before, so I rode the bike home, and checked in my driveway. I did discover that the cover on the left side is wet on the bottom, and I watch oil drop form down one of the screws on the bottom, and drip on my driveway - see photo attached.
Now, my bike is always parked in the same spot on my driveway, and there was never a single drop of oil. I know the oil that I used is highly regarded as one of the best oils, full synthetic German product.
I went there with my wife to help me check the oil level, and it turns out I overfilled it slightly. I couldn't get the bike perfectly upright, I used a 2.5" metal block under the kickstand to get it almost upright when filling oil, and I filled the oil exactly up to the upper line. But when my wife held the bike perfectly straight, the whole sight glass is covered. I put in exactly 2.5L of oil in there, could that be the issue?
Either way, looks like I am in need of a new gasket. Anyone have the OEM part number, of if there is a gasket that is better quality than the OEM.
