I would love some advice on how and what would be a good donor snowmobile to use. will be racing on 300ft sand tracks and looking to run a max of 5.5 to 5 seconds. also do I start with an atv frame and mod it or build a rigid frame from scratch? Plus any and all other advice will be great.

 

go get a recked thunder cat efi or wild cat no bat, ripps hard, just make the frame

 

what is the engine size? Twin cyl and or is it a two stroke?

 

I'd say a polaris 700 twin. Mostly because they're really common and easy to come by. I ride a 98 rmk 700 and my only problem has been a broken hood, but thats another story.[img]i/expressions/face-icon-small-wink.gif[/img]

 

There is a guy on the Bombardier forum that put a Ski-Doo twin cylinder,two stroke in an older Polaris chassis.I assume he took advantage of the CVT drive train that came with the atv. Fabricating an exhaust could be a challenge. Sorry i can't remember his name ,i think he lives in Wisconsin.

 

Thanks

 

I have a 2001 artic cat 1000 triple with a hooper 1100cc top end kit mounted in an ultra light +14 banshee frame but in order to get it to run 5.5 in the 300 you would have to pull off 2 plug wires LOL

 

Yeah, not quite what I am looking for[img]i/expressions/face-icon-small-wink.gif[/img] but still sounds cool

 

there is a pic of it in my pics page. the purple bike

 

Cool pics, do you ride/own anything that is close to stock[img]i/expressions/face-icon-small-cool.gif[/img]
