    Wet sump is fine for cars/trucks, etc. It's a simpler, less expensive system. The engine in these vehicles can sit as low as needed and still have plenty of room for a deep, conventional oil pan. But even a few inches of motor height makes a world of difference in a motorcycle or similar application.
    BRP / Rotax would be brilliant to step away from the current design. For such a modern engine, it was foolish to go with shared gearbox and engine oil. Yes it works, but the engine would benefit from better oil additives that sadly the clutch does not like, and the gearbox could shift better with a dedicated gearbox oil that may not be suitable for the engine.

    You realize that you are advocating for added expense, added weight, added bulk (size), and additional complexity. Not to mention greater maintenance time and cost. All with no real advantage. Quite suitable, well performing lubricants at a reasonable price are easily gotten for the current system. And after over 10 years of Spyder production, I have not heard of a single owner complain of a worn out motor or transmission. Granted, some have destroyed their wet clutch by using the wrong oil. This is unfortunate, but completely avoidable. Not a good reason to abandon what I consider the best approach possible for the Spyder. Every option has a downside.

    Honda, BMW, Kawasaki, Suzuki, KTM, Ducati and most other motorcycle manufacturer's use this same design because it fits the bill and works so well. Even Harley uses this in the V-Rod. Most of the motorcycles using separately cased drive systems do it more for nostalgia than anything else.

    BRP and the Spyder do have some issues. What mechanical devise doesn't? Room for improvement? Sure! Just not in this particular case.

The number of minutes after you shut the engine off it not that critical just as long as it is within a reasonable time. I think probably they put a certain number in the books to keep 50 people a day from calling and asking how long to wait.
