is there any 3 wheeler that had, or is there a way that had the 4 stroke 250 motor with chain drive. is the 250r bottom end compatable? just spinning the wheels here, 250 cubes, 15hp is cool, but the weight of the shaft drive is kind of a downer.

 

Maybe you could do something with a 250 x motor. You would have to do some modifications to make it fit though.

If I didn't want shaft drive I would either hop up a 200x or go with a 350x.
A 200x has pretty good power with the right goodies included.[img]i/expressions/face-icon-small-happy.gif[/img]

 

Oh yea, the 250r bottom end will not work with a 4 stroke top end.

 

nope it wont. I dont think the shaft drive is that much heavier. And you can still get some travel out of it. Check mine out

 

Oh yea I thought the 86-87 200X had 17hp.
