this is what i asked this morning : does the engine still get fuel/air from the carb? or is this like fuel injection. also does it need to be adjusted for elevation.
this is what i got back: Thanks for your interest,
First and most important, carburetor setup is included with your purchase ($239 Visa or Master Card). I fit the jet tube and do all the custom mods including a special needle. The air-fuel flow through your stock intake jackhammers back and forth. This pulsating not only robs you of power, it messes with jetting and makes your carburetion more sensitive to weather conditions.
The Power Jet Intake is high velocity Path of Least Resistance Continuous Flow system. High Velocity Continuous Flow Induction ( CFI ) pumps it own barometric pressure, thus it is not effected by altitude. However, a rider in mile high Denver will have a slightly leaner base line setup than someone at sea level. Another sweet feature of Pulse Charging is that all the needed adjustments are made by just turning the air screw. No more moving the needle clip or changing jets when the weather changes, ¼ of turn does it all. I use Zip Tie’s big blue air screw. It’s easily adjusted, even with your gloves on.
Now for the fuel injection question. I obviously like high tech stuff. However, injection squirts the fuel, ok injects, the fuel whereas a carburetor mixes air and fuel even before it enters the intake track. This oxygen rich, homogenized mixture make for a more complete burn. This is why carburetors make more power. Eliminating the problems associated with carburetion and using the energy to Pump Up the Power is not only better than injection, it’s low cost and bolt on. By the way, Power Jet Induction also works excellent on fuel injected 4-stroke bikes, but there is no way they can run with a Pump Up 2-stroke!

i like the concept and if jetting works like he says it might be a good deal. he also gave me his number so he dosn't seem afraid to talk about it. might be a good xmis gift for myself.
