slarson,
I did not communicate very well what I had intended to in that last post. What I had intended to point out is the fact that Fuji (Heavy Industries) is responsible both for Polaris Fuji engines as well as Subaru automobiles. Now, I don't know exactly what connection they have with Subaru automobiles but you will see marks indicating the involvement of Fuji in some aspect of their production if you look under the hood. Exactly what connection Robin has, I'm not sure about but they, also, are somehow connected.
In regard to Fuji engine designs, the latest one I am aware of was the 550 fan which, to look at is largely a great advance over the older engines of similar design. How it has actually worked is another story and it was, IMO, one of the dumbest things Polaris has done (dropping the 440 and 488 fans for the 550) recently aside from some of the gas-sucking domestic engines they have concocted.
Since I'm going off now, I guess I might as well vent some of my disdain for the Ficht technology which Bombardier now has rights to (which are leased to Polaris for its 4-stroke Frontier). I have used a Ficht injected fuel engine for 300 plus hours. The one I have is an outboard. I purchased it for two reasons: one, it burns less fuel and therefore runs somewhat cleaner; two, it was lighter than similar powered 4-strokes. There were problems with the early versions of these Ficht injected engines. I don't know what changes have been made but the 2002 equivalent now weighs slightly more than its Honda 4 stroke counterpart. Injected 2 strokes aren't necessarily lighter than 4-strokes. The engine runs admirably during the summer months giving less trouble than carbureted engines. When it gets cold, below freezing, the potential for problems increases exponentially. I'm not sure how Polaris will deal with it. Hopefully they'll make it work as well, if not more reliably than carbed, and get the weight cut back to boot.
