May not be Moto related but..
I saw an interesting technical paper presentation today at the SAE Powertrains, Fuels, and Lubricants Conference in San Antonio. The research done by the University of Bath in UK studied 6 types of 2 stroke scavenging applications for automotive purpose. They found that the opposed piston two stroke (OP2S) was the most ideal for light/medium duty applications. This type of engine is already very popular in the heavy duty diesel world. Would be cool to see a single cylinder, dual piston/crank motocross bike, though probably not worth the trouble developing. Thought some of you jerkies might be interested...

Scuderi 2 stroke (though R&D stopped on this years ago it's still interesting)

Burt-McCollum Sleeve Valve (A sleeve between the piston and cylinder that moves relative to each and opens ports at ideal times.)
