AC 2 stroke engine project was started long before your time line. Years. Yamaha sled from Japan is no more than wishful thinking. I won't step into that trap again. The AC built sled with Yami engines is what the future is. For how long??? Textron is going to produce there own 4 stroke engines eventually, imo. The engine production capability was a big part of that purchase. If AC/Yamaha would produce, a all new sled, with the chassis/engine combination designed from the get go, they will really have well balanced/handling snowmobile. That's what many had waited for Yamaha themselves to produce for too many years.
