a street bike motor will go through a set of tires in one ride... and just get a big bore atv motor.

 

Would you recomend the 660 or something else??

Also: how do snow mobile engines do when not in snow??

i am gonig to use a 660r motor..

 

Use a liqued cooled snowmobile engine

The engines are high HP, belt clutch, light weight. Just use a radiator and maybe an electric fan.


A heavly modded 4 stroke snomobile engine can produce over 300 horsepower if you wanna get really crazy, but a good 800 two stroke is usually sitting around 130 horse with slight modding and pretty reasonable priced, this is just off the top of my head but if you wanna visit some snowmobile forums you'll get a good idea what kinda power these things are producing..


Older engines around 440 in size are very cheap and still give you more HP than you'll find on an ATV engine stock.

 

Check out these for inspiration

 

Wow thanks for the site thats sort off what I am aiming for. I will keep looking. I found a guy who is selling a 660 engine for $700 what do you think? It seems cheap compared to the price of the bike but I really donn't know.

Any other thoughts?
