Default The Future Of The Two Stroke

Looks like the four stroke club will be devoid of a few members real soon...

My Yamaha outboard is a two-stroke.

I guess I'm on the cutting edge.

China has already bought patent rights to produce the Orbital version of the same direct-injected two-stroke technology on thier new sport, street and dirt bike line that meets or beats all current US emissions rules and regs.

The two stroke is back. Just wait 'till the auto folks get ahold of the technology. Motors that weigh 100 lbs and put out two hundred horses, and get better fuel and emissions readings.

At a dealer near you.

And cheaper to produce too!

This can still be stopped if the big companies get the EPA to simply ban all 2-strokes without exception. Look for Honda to attempt this.

Your Yamaha HPDI (High Pressure Direct Injection) is actually more capable than the DI system in the article. Ten years ago, Yamaha was running their injectors at 750 PSI. The Bombardier system in the article is only at 500 psi. Higher pressure means better atomization, and that means more complete combustion. Cleaner, more fuel efficient, better power to weight ratio.

I guess you haven't been stalking me as well as you should have Kenneth. Sadly, my dear Yamaha does not posses HDPI.

I"m running garden variety carbs on my 115. Still kicks ass though.

Carburetors are the devils playthings, please deposit them in the briny deep and get a fuel injected version
