I just picked up a 2006 rs venture with truly only 47 miles on it... I know where it came from so I know it's acuarate. So what needs to be done with such a machine? It certainly has not been broken in. So what should I be looking for, for maintenance issues before the snow flies? Is there any must do mods? If I add a set of marginal snow wheels should they go on the front or out back? My other 2 sleds are 2000 vmax and a phazer so I have no experience with this new technology.. Any info would be great!
