We have 2 Kawasaki STX12Fs (1200cc 4 cylinder 4-strokes). I run Mobil 1 Euro 0-40 in them, before the Euro formulas came out I ran M1 4T in them. I run euro formula now just because it is easier to find, I have 2 to maintain and it comes in a 5qt containers.
Honestly though, they are pretty much motorcycle engines but with lower rev limits and no wet clutch, so anything you would run in a street motorcycle engine would work fine.
I like the 0 weight oils because people that don't have to maintain them, rarely let them warm up at all before they are waaaay up in the RPMs.
