Good information. Good Video

One major point that should be noted before you watch the video. The sled has 60 HP! That will be a very small market.

True, how many h.p. is the 600 E-Tek?? I would think aftermarket would get this to 70-80 h.p. pretty easy and still have really good mileage. Plus 4 stroke longevity. At least we know where doo is going now. Look at the first Yammy 4 strokes and where they are now. And I would say from what I have heard about the 1200 4-tek that doo is way ahead compaired to where Yammy was is 01....

I doubt very much if there are any aftermarket companies that will be able to improve E-Tek performance by 20%. It is a very complicated, very sophisticated system best left alone. The aftermarket companies simply do not have the tech to even start modifying an E-Tech. Also, Yammi first put their R1 based 4 stroke in the RX1 in 2003, not 01. Since then they have added fuel injection and a lighter crank in 2006. For 2011 they are re-doing the fuel injection system. They still have the cross-plane R1 engine waiting in the wings. They have not been standing still. The 1200 'Doo motor is a welcome addition although it is not in the same league as the Yammi 4 banger unless it is turbo'd. They ALL have room for improvement but as time goes on things have become so complicated that soon the aftermarket companies will be supplying only things like skis and studs and clothing.

don't forget that in 03 when yammi introduced the 4 strokes mpg was a major focal point of the new lineup. I know this because I watched all the hype and even bought one, it was part of the sales pitch and rightfully so. In 03 we had a new 145 hp 4 stroke sleds weighing in at around 600 lbs. Friggin thing was a rocket and a cadillac all in one. Now some 8 years later we see etech with same sales pitch promoting incredible mpg, and oil consumption. I am agreeing it is awesome to see what they have done. Some things to note here, doo is over 100 lbs lighter and still a 2 stroke. Yami and doo very different, both awesome in their own way. Don't forget, if your in the throttle your gonna see both sleds suck it down. My buddy has a ete and loves it, I rode it and love it. It does very well on fuel but he is not a johny rocket. When I babied my rx1 it did awesome, People could not believe I could get the mileage with the performance.

Point is, doo did a great job with the etek but it's gonna take some time to get real numbers from one side of the grandpa ride to the jonny rocket ride, right now hype is a big factor. It may sound like Iam sceptical of doo with the etek but not true. Just pointing out the natural hype that comes along with new tech. Is it good on gas, **** yea and I want one! But when your off trail and the hammer is down and thrill is the main factor, I personally and not very concerned with MPG. Do you realize how you would have to ride to get 29 mpg?

I disagree. The automotive aftermarket has mods for new cars as soon as they hit the showroom. There are brilliant engineers in the aftermarket business, and I think it will be easy to mod future sleds. For most systems, all you should need is a remap of the electronic control systems, and you get instant power. That is the direction we are headed in. OEM's are conservative on the side of reliability. I am sure there is lots more power in all the new sleds just waiting to be found. It will be even less expensive to mod a modern sled because you won't need as many physical changes to acheive results.
