This a clip that I found pertaining to the 2-stroke vs 4-stroke snowmobile emissions and mileage issue. Not thrilling but interesting.

Both of my snowmobiles are fuel-injected 2-strokes. I have a 2008 Polaris 700 RMK Dragon and a 2008 Polaris 700 RMK. They are both mountain snowmobiles that produce 140 horse power with the new fuel-injection technology. My 2-stroke snowmobiles are about 70 - 80 pounds lighter than comparable 4-stroke snowmobiles and they make more horsepower. What would you ride?

Both sleds have 155 inch long tracks with 2.4 inch paddles to float in the mountain powder snow.

Just strap on the snowboard and go.
