SmartCarb appears to split the gap between fuel injection and regular carburetors. It's a huge improvement on carb design in that it behaves more like fuel injection. Fuel injection is computer controlled and is the most precise but costliest form of fuel delivery. You will continue to see fuel injection on high end street bikes because the cost savings smart carb could offer is not worth the loss in computer controlled fuel injection.

Like I said, smartcarb is a niche product but a HUGE niche product. Don't expect to see them in GSXr's or Valkyrie s. But DO expect them in the millions of lower end bikes used overseas and in the developing world.

And not to confuse more, but those MotoX bikes getting high revs out of the smart carbs are 2 stroke engines while conventional motorcycle engines are 4 stroke.

With all that said, go FROGS

2-stroke vs 4-stroke

A Common List of Advantages and Disadvantages

Advantages of 2 Stroke Engines:
- Two-stroke engines do not have valves, simplifying their construction.
- Two-stroke engines fire once every revolution (four-stroke engines fire once every other revolution). This gives two-stroke engines a significant power boost.
- Two-stroke engines are lighter, and cost less to manufacture.
- Two-stroke engines have the potential for about twice the power in the same size because there are twice as many power strokes per revolution.

Disadvantages of 2 Stroke Engines:
- Two-stroke engines don't live as long as four-stroke engines. The lack of a dedicated lubrication system means that the parts of a two-stroke engine wear-out faster. Two-stroke engines require a mix of oil in with the gas to lubricate the crankshaft, connecting rod and cylinder walls. <--see sonicflow engine for a fix
- Two-stroke oil can be expensive. Mixing ratio is about 4 ounces per gallon of gas: burning about a gallon of oil every 1,000 miles. <--see sonicflow engine for a fix
- Two-stroke engines do not use fuel efficiently, yielding fewer miles per gallon. <--see smartcarb for a fix
- Two-stroke engines produce more pollution.
From:
-- The combustion of the oil in the gas. The oil makes all two-stroke engines smoky to some extent, and a badly worn two-stroke engine can emit more oily smoke. <--see smartcarb for a fix

So, if there are solutions available to make a lighter, more powerful, more efficient powerhouse....Why do you think pro riders are on this tech like flies on cow pies?
