Those are pretty cool engines, I just sold a SkiDoo with a 583 in it, I thought long and hard about it and I'm pretty much a 2 stroke MC guy. But I am going with a Suzuki G13BB 4 stroke. Mostly fuel burn at cruise, TBO and no oil ect... Not stuff I care about with dirt bikes, but for my airplane? And possibly the only one I''ll ever have, 4 stroke is my path.
