Rotax 720

[akflyerbob 41]

I read some where about several guys running a 720 in their kitfox. Any know about this? 

I've look around and they have a 700 and a 720 motor both 2cyl.

Are you referring to big bored 670's? In sleds people used to over bore them and use a seadoo 720 or 787 piston to make a 720 or 740. Or used a polaris 700 twin piston to make a it close to a 700. I think there's a guy in Florida and another in utah running a 740, I forget where I read it. Mike hair would know, he was making the exhaust. Actually, it might have been his plane. Have you got your 670's flying?
