I posted this over at PWCT, thinking there would be a bigger audience, but I thought I would put it up for discussion here too...

This sounds like a crazy conversion, and I dont know if it has been discussed, but I thought this would be a good place to bring it up.

Reason I started this thread is because I have a set of Billet couplers that I believe would allow someone to make this swap...

These have 18mm threads on the engine side (should fit all Kawi 550, 650, & small pin 750). And 24mm threads on the driveshaft side (fits Yamaha SuperJet 650 models, 90-93 midshaft)

Squarenose SJ hulls come up for sale pretty frequently, and many Kawi guys already have modified engines... hmmmm?
Bedplates and/or mounts would have to be fabricated to line everything up.

Any interest? I would have listed these in the for sale section, but I figured it would get lost there... discuss... ideas???... offers?

Neither one of these will fit a Yamaha crankshaft... The 18mm will fit a Kawi crank. The other will fit a Yam 650 intermediate shaft (different threads than the crank)
 
Here's something pretty close.........

First pic is a Kawi 750/800 someone put into an FX-1

Second pic is a 900 zxi about to go into an FX-1 :dance:
