That's a good one air. How about a Ducati.

 

I always thought a Kawi 750 2-stroke tripple would be nice. I saw a shee with one at the hillclimbs. That thing would rip. Its a small, compact motor so it would be a good candidate if you don't mind ring dings.

 

Last weekend I saw a R1 in a zilla. Very clean installation with custom header. I think he ran 5.70 in 400ft. on dirt.

 

A guy I met @ St Anthony a few years ago had an LT250 with gx1100 air cooled engine. He was a machinist and did a job that looked good as factory. The frame remained flat on the bottom without that hang-down cradle you often see in a street bike motor quad. That frame redesign took most of the work. He said it was real ridable, not fussy, and was a pleasure to cruise the dunes on but you just don't go getting a bunch of air. It was huge fast too. Brian at Armadillo Enterprises has a DS650 with an 1100 Yamaha in it, and it turned out real good too. When you sit on it you don't even see the motor sticking out. Big time speed. I think you better be pretty handy with a wire feed to tackle a project like this.

 

You need to get a hold of SirClip. I wonder if he's got that CX500 monster quad going yet.[img]i/expressions/face-icon-small-happy.gif[/img]

 

I have a buddy that races snow mobiles and may have an extra engine..
