Just think of the possibilities without the need for a huge expansion chamber. Would be so nice
The Ski-Doo ETEC's all have expansion chambers. It looks like the same size as a non-ETEC'S motor. They also have exhaust valves. The plugs are good for 10,000 miles. One pull and the sled starts every time. Runs and idles clean. Cleaner then the 4-strokes. No smell and no smoke.
The etec motor is still a simple motor. It is the computer that is doing all the work. Some say the computer could go...I don't think I have heard of one crapping out. I'm converting my fleet over to etecs in the next couple of years because the motor is really really good.
