I am thinking about buying a used engine for my bike over the internet. The seller says the engine has been stored in oil ( I am assuming engine oil but will check) for 11 years. I have never heard of anyone doing this before, so I'm not completely sure if it's a good thing or not. Any opinions? Any problems the oil might have caused, to the clutch or anything else? The bike is an 84 Yamaha TY250L, the engine would be very similar to the same year IT model, at least as far as this question goes.
