I see dozens of different exhaust and air cleaners for moving air through the motor . But very little for moving fuel . I see only one screaming eagle injector kit and it's for the M Eight . Why can't Harley make hi flow injector kits for the guys with twin cams ? This seems like a good way to get fuel into the motor to go with the exhaust an air cleaners and why buy bigger throttle body it just lets more air in .
Wouldn't a hi flow fuel injector kit be just like getting a curb jetted out larger ?
And wouldn't this be cheaper then a tuner .

 

there are many larger injector sizes out there, for tc.

 

We need injector kits that are just .2 or .4 G/sec larger then stock injectors . So it's a quick mod just like changing out the air cleaner .

 

may be quick, but injectors are expensive, and minimal increments would not be profitable to the manufacturer. also its easier to just change the opening rate to allow more fuel than to try to let more fuel come in. Thats what makes FI so great, is that it is so adjustable. Also it doesn't work like a carb jet, there are so many more infinite adjustments it makes based of manifold pressure, throttle opening, ect. it not just a matter of allowing a bit more fuel in, everything has to be taken into account. You try to make adjustments like you talk about, and you will have a very poor running bike.

 

That's just not the case there are several over sizes of intakes and injector sizes available in the SE catalog. You won't find them in the parts catalog.

I haved used a couple of larger than stock manifolds and injector sizes in past motor projects.

I believe the injectors were around $40.

 

check my post #2! I agree, but it sounds like the OP is thinking like jets for a carb, kinda deal

 

Here's how you do it

Power Commander
Power Vision
V&H FP3
Vieds
Screamin Eagle Pro Street tuner
Etc....

All of these "limited choices" will let more fuel flow.

 

The injectors are in the throttle body which is behind the air cleaner, so that would be a good trick. It takes about ten minutes to install a Power Commander.

 

The Factory injectors are capable of adjustments up to stage 3-4. The stock injectors don't need to be changed until the duty cycle gets above 90%. Until then the Fuel and spark is adjusted via a quality tuner. So you can "change jets" with the push of a button.
