Do you think Yamaha should go back to a two stroke plant to build a light weight mountain sled?

My question is legit if Yamaha won't build a light 4 stroke mountain sled then they should build a light nimble two stroke mountain sled. Simply because they are not building a mountain sled for Canada anymore.
I am not sure that the two stroke engine is the answer. I am sorry if I sound like a broken record, but again please look at the numbers of the new Arctic Cats. Their turbo four stroker is around 25 kilograms heavier than the FX Nytro engine, still the total weight of two comparable sleds is almost identical. Same thing with the Doo 1200. I do not remember the exact weight of this lump, but I do remember that it is quite a lot heavier than the FX Nytro engine. Still, the total weight of their comparable sleds is
lower than the FX Nytros...This tells me only one thing - the american brands are building lighter chassis than Yamaha, still there is absolutely no proof that they have got more durability problems. Or, put it this way - Yamaha are giving the four stroke engines a heavyweight reputation because of the chassis they are delivered in...
My feeling is sometimes that Yamaha is right in the middle of dropping the ball on the whole four stroke snowmobile thing - because of the chassis. The introduction went quite smooth because even though there was additional weight, most of us accepted that. Because we wanted a four stroke engine and because we were hoping for and dreaming about future weight reductions. But we are now nine years past the first RX-1, six years past the fuel injected and updated Apex and four years past the first FX Nytro. Still, the lightweight chassis generation that we are dreaming about seems to never show up...And I am not at all sure that the synthetic lightweight feel created by
adding weight with power steering is the answer. At least not for the mountain business...
