That would be better than a Jet Ski motor in an R1. Anyway, shouldn't that be an R1 motor in a wave runner?

About five years ago I saw a Watercraft Magazine article about a Sea Doo with a GSXR engine in it.

I just dont know if those motors can take the constant load-high RPM abuse without major mods to internals??? DrEvil

Default No, you got it!

I want the jet ski's motor. One of those liquid cooled two stroke triples, although maybe in something lighter than an R1.

You'd do better with a snowmobile motor (a la Tularis ...the watercraft motors are quite heavy, while the sled motors are much lighter given the same displacement. I for one would love a 700cc 2-stroke twin or triple in a streetbike, except for the fact that they present a huge vibration problem in that sort of application.

yeah, there was a carbon fiber framed 583 rotax/bombadier motored streetfighter looking thing in Twistgrip magazine. 310 pounds and hayabusa power level, with a CVT drive. The same guy made a feet forward version too. I like the way the jet ski motors look though, do they have transmissions? Looks kinda like a modernized GT750. I'd make a chopper out of it (I said lighter, not better).

The trick seems to be in making the four stroke engine work upside down and/or being easy to start after it has flipped -- a frequent thing with PWC's.



R1ski...thats good.
