I think it would look bad ass,especially if doing some street racing. I know it wouldn't be good if trail riding because the belt would slip.but I didn't know if it could be done or if has been done to other quads.
I'm takin it you mean you will leave the stock motor and trans on there just change the chain drive to belt correct. I don't think it would be very good idea myself unless you use a strong belt with some big teeth to or grooves.
