There is no doubt the cat motor is more reliable. My t-09 m8 never let me down. I don't think the 16% is acceptable for polaris. I am selling my turboed pro just because of that fact. I don't want to throw $5000 out, if the motor goes, on a used sled. I still don't understand that because I was getting short blocks for doos for $1700. Maybe $2400 installed. It has been an awesome sled for the 1300 miles I've rode it and has never blown a belt. Trading it for a 13 and warranty.Keep the 12 for one more year. Yeah, if it had a cat motor in it I would keep it another year or two. I will say one thing, the 13 pro is going to be the first sled, ever, that you don't have to do anything to to have fun. Sure they can all be clutched better and need better shocks but they are lighter, get up on the snow better, one of the easiest sleds to work on, and just flat out fun in the trees. I guess I am willing to live with the motor trouble but I will have warranty.
