The only thing that complicates this engine really is the abundant use of FIPG. It’s actually really easy to work on other than that. You don’t even need beer. I suspect they aren’t popular because simple tasks like coil packs, valve adjustment, plugs etc aren’t practical without pulling the engine. The only real advantage they have is low CG so it’s only really logical to put them in a sports car and there just aren’t many sports cars. Manufacturers want an engine that is easy to maintenance that they can use in all their cars not just sports cars.
