I don't think 2 strokes will come to an end, way too much demand... The technology is picking up, look at the ski-doo SDI technology, it's 2006 emissions approved, and I'm sure they could step it up even more... I'm not too worried, it's about time they put the money to make 2 strokes more efficient, then we'll be getting even more bang for our buck when we pick them up at the dealership. As long as it doesn't choke them up like it did to the older muscle cars back in the early 70's I'm all for it. There's no way around the light compact setup of a 2 stroke for a snowmachine, they're going to have to do so much more to four strokes to get the power to displacement more even between the two... There's too big of a gap along with weight to just get rid of them.... Can you see yourself holding a 4 stroke weedwacker for more than 5 mins? Haha, don't think many of us would put up with that, especially when we tip it sideways and it seizes up, just like what you would need for a chainsaw! Can't beat that need! They are a necessity in so many ways!
