This article was written by Phil Mickelson at Snow Goer magazine. More in-depth information about fuel injection on two-strokes. While these are not motocross applications you can see how they could be adapted to MX bikes.

"When U.S. Environmental Protection Agency regulations for snowmobiles started in 2006, Ski-Doo already had its 600 H.O. SDI two-stroke engine on the snow for two years. It was considerably cleaner than regulations required and it achieved industry-leading fuel economy. The engine was light, powerful, dependable and clean.

As the Bombardier Recreational Products (BRP) Evinrude group developed the E-TEC system for its outboard motors (BRP acquired Evinrude in 2001), it became clear that this technology could translate directly to Ski-Doo snowmobiles. In the winter of 2008, Ski-Doo released the 600 H.O. E-TEC engine.

Is the E-TEC engine a big deal in the world of snowmobiling? Absolutely. It demonstrates that the two-stroke engine — with all of the advantages it offers for snowmobiling — is far from being axed from snowmobile manufacturers’ product plans. The 600 H.O. E-TEC is available across Ski-Doo’s 2009 lineup and further expansion of the direct injected technologies will prove the strength of the two-stroke engine design and its attributes."

As mentioned earlier, this LOTUS OMNIVORE engine offers great hope


for the two-stroke, too:

And it can run on Southern Comfort !


" The Lotus Omnivore engine uses a variable compression ratio system with a 2-stroke operating cycle and direct injection. The Lotus Omnivore engine has been developed for flex-fuel operation and offers better optimization than the four stroke engines."

Direct injected two strokes have been around for several years in personal watercraft. KTM is supposed to be close to releasing an injected 250SX. Found this a while back:

haven't they had fuel injected scooters for a long time now (smokers).

the four stroke "craze" will have to play out before they "announce" the new, light wieght. fuel effiecient, less polluting 2 stroke FI machines.

likley by that time the bikes will be 11 grand and only a small percentage of what we have left for riders now can afford to ride anything.......

cool non the less.

Have to be a Fed or State pollution mandate for a DI, not just FI two stroker to be mass produced again. Yamaha has DI boat motors as well and yes Wardy, they won't come cheap.

Husky is suppose to have a DI 125 Street or Dual Sport just in Europe already being sold for a while now.

Whether we ride or not, trickness of new technology still sells.

I know of since '04 that CARB has had DI engine entries win awards in the small engine category; the ones for motorcycles, boats, etc...might've started even earlier, but '04 is first I heard of.
