Well, you probably know this anyway but just to confirm, changing engine oil does not require the removal of any plastic covers. If you can raise the bike about 12 inches higher, that will help. The only problem I encountered was my container that will receive the old oil almost touching the engine (bike on center stand) and that hampered removal of the oil filter due to limited space. I am trying to create a way to change the transmission oil as well without removing plastic but that one seems a little tricky. The easiest way would be to pump the oil back into the same hole where it came out but the entering oil will create pressure inside and that air will want to escape at the same time as the oil goes in. A work in progress.
