Removed old seal today and found some strange things. The seal was in very bad shape with part of the rubber separating at the top - no wonder it was leaking like a stuck pig. Also, had some rather large chunks of silicone adhesive wedged between the seal and the cases which I assume caused the problem to begin with. The oil looked fine with around 1 qt still in the crankcase and nothing on my magnetic drain plug except the usual gunk that collects there, so I don't think I did any damage to the engine. Spent a good while cleaning the area to remove any dirt and smaller pieces of silicone around the bearing. I'm assuming this was caused by too much instant gasket that dislodged from some other part of the engine. Testing the bike up the street it seems to be OK with no oil leakage, but I'm not sure if I fixed the problem or if this is a symptom of a bigger problem. Anyone else ever seen anything like this? Any feedback is greatly apreciated.
