I think 2-strokes have the cold weather advantage. Sure I'm a spoiled rider now with a 28' enclosed and heat but there was a time when i needed to get to school, work, ect.. in North Dakota. You could leave an old 2-stroke outside uncovered for weeks and get it to run on several pulls. I fear the batts on 4-strokes and extreme temps.
My turbo Nytro starts at -35 way easier than my rmk 900 summit 800 or summit 700 ever did, I live in Alaska, its kind of cold here. I used to think four strokes would be hard to start also, but its way easier to turn a key than rip a pull starter or your arm out. As far as fuel mileage you can't beat them, my wife can follow me around all day on her Phazer and only burn a couple of gallons, her summit 700 would have burnt a full tank of gas not to mention oil. I bought a Yamaha because I was fed up with 2 smokes, its insane that a brand new 10,000 machine needs to be rebuilt after only a few thousand miles( a Yamaha engine can last 40 to 60,000 miles). I was also fed up with 2 smoke dirtbikes years ago, rebuilding the engines every year I thought was bull. I bought a yzf 400 the second year they were made in 98, I still ride it, on the original engine, change the oil once a year and go, I ride a couple times a week every summer since I've owned it. I would love to buy a new yfz 450, but until my 400 finally burns up I will keep riding it. My only point is that I cannot possibly justify buying another 2 stroke. I am not pushing four strokes on any body, just stating the reasons I will never own a two stroke again, and I have owned many.
