I recently noticed a tiny amount of oil on the garage floor under my bike. After a 30 second review, it appears to be coming from the stator cover. Any ideas? Also I'm tuning her up for spring, so what all should I do? I purchased a NEW battery, stator & cover, chain, sprockets, plugs, grips, oil & filter, air filter, front brake lines & pads, and am going to have my valves adjusted. I'm at 16k miles. Any other recommendations?
