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."

Great news, now if the big 4 do something with that or ktm that would be great!!
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."

Revolutionary New Two Stroke – Ossa TR 280i
Story on this bike..
The Shop
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.
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.
