Let me preface this by saying I know nothing about bike repair, I hope someone can help me with this. Last fall when I was getting my bike ready for winter something went horribly wrong. After I added the stabil to the fuel I was letting it run for a bit and I think I may have let it run for too long, my bike started to kind of spray oil, when it is sitting right after running it looks like oil is dripping from the exhuast on the bottom of the bike, it doest seem to leak when the bike hasn't been running, only immediately after running. I'm not sure if it is ok to even ride to a mechanic, I don't want to do any more damage than I have already. Any thoughts?
