Are snowmobile engines 2 or 4-stroke?
The two-stroke snowmobile engine is, mechanically, very simple, but how it breathes is rather complicated. A four-stroke engine separates the intake, compression, power and exhaust strokes with the use of poppet valves, but it only makes one power stroke every 720 degrees of rotation of the crankshaft.
How long will a 2-stroke snowmobile last?
Snowmobile 2-stroke motors will last 10,000-20000 miles depending on model and how well it is taken care of before they need either a top end rebuild, or a bottom end rebuild. You have about the same chances of blowing the motor at 10 miles as at 7500 miles.
Is 6000 miles alot for a snowmobile?
There are lots of forums out there to read which models are good and which ones give trouble. 2000 miles isn’t a lot but on some motors that milage will make it a time bomb. I’ve seen 6000 mile sleds look better than 1000 mile ones. It all depends on previous owner just like anything else.
Do 2 stroke snowmobiles need mixed gas?
Most modern snowmobile engines are designed to run on 87 octane gasoline blends. Many older machines, especially high-performance models, require premium fuel rated at 92 octane.
Is 4000 miles alot for a snowmobile?
Your looking at 150 miles a year average or one good afternoon of riding. For a snowmobile under 4000 miles I would consider low, 5000 – 8000 medium and 10,000 and up high. But all depends on the year. I put between 2500 – 3000 in a good year, 1600 – 1900 bad year.
Why are new snowmobiles so expensive?
The fixed costs, raw materials, sourced components and manufacturing costs must now be spread out over a much smaller build quantity, thereby requiring each sled to bear a much greater cost per machine. The 1995 XLT is an example of just how much volumes have changed over the past 15 years.
