A new Spyder TT in the works?

[bscrive]

In 2005 Ski-doo re-released the Mach Z with a 171hp Semi-direct Injected 1000cc twin. That "dinosaur" had better emissions ratings than the Yamaha 4-strokes and is still one of the baddest "Lake Monsters" out there. I can speak from experience about the power and fuel efficiency of that sled. Since then they have brought the "E-tec" and "ACE" motors to the market. I am willing to bet that if anyone can "Doo" it, Bombardier can.

What I am wondering is why the guy from Alaska is not more well versed in snowmobiles???:yikes::joke:

The only difference with the Yamaha 4-strokes and the 1000cc Rotax is that I have seen many Yamaha 4-strokes with over 20000kms and going strong but few 1000cc Rotax engines that were not blown up before they hit 5000kms. 4 strokes are by far stronger engines in just their design alone.nojoke

Ouch! I see the joke sign though. Sorry, but I don't drive snowmobiles and have never driven one while here in Alaska. You cannot use them on public roads, so that discounts riding in my neighborhood. Most of the places people go to ride are avalanche areas, or very rugged--of the type you would not want to break down and get stranded. We lose a few snowmobilers every year here.

RE: two cycle--I was not aware they were still using these. I did have one motorcycle, (1964 Yamaha 80, a one lunger), two cycle, and I did have a car (1966 Saab, 3 cylinder--four on a tree--add oil to a tank for mixing.) Very anemic vehicle and got only 35 mph in those days. That's my total experience with two cycle other than chain saws and weed eaters.

That might not be completely due to the engine...
How they're being run has a lot to do with it as well :shocked:...
A two-stroke that's been tuned to within an inch of it's life in the quest for the lowest e.t.s is just doomed right from the start... :yikes:

No, thanks! I'll stick to two wheels in the dirt. But as far as the 2-stroke vs. 4-stroke argument, the only advantage that a 4-stroke has is that it oils better allowing it to turn higher RPM's, and with the latest technology it's losing that. Two-strokes make more power per cubic centimeter and a lot more power per pound of weight. They are almost maintenance free compared to 4-strokes and much, much easier to work on. The most fun street bike I ever owned was a Yamaha RD-350, 2-stroke twin. It would accelerate with most 750's even handicapped by an unskilled rider. Most of the Japanese companies have stopped building 2-stroke dirt bikes except a few motocrossers. Partly as a result of that, KTM, which still builds excellent 2-stroke off-road bikes has almost taken over the off-road market. At our club's National Enduro in March, I worked the start and checkpoint 11, near the finish. My guess would be that at least 75% of the bikes we checked through were 2-strokes. Two-strokes aren't dead by a long shot and I hope I live long enough to see them make a comeback on the road. Cotton Oh, I forgot, 4-strokes also have the advantage of better fuel economy but fuel economy isn't usually a big consideration in the dirt and new 2-stroke technology is improving 2-stroke fuel economy as well as emissions.
