I was searching a little while back and seen a post about which 120 sled to get and why? Well I was at Pinkleman's (artic cat) in Newberry Mi this past weekend and came accross something really interesting. The 120 Cat sled has a Yamaha engine in it. Now since the R&D is already there for this engine why not get the chasis together and put a REAL 120 Sled out!
