GET Dual Injector Kit Background
The Ultimate Upgrade

The "Huge" 2-HP Gain

That Exhausts and Pistons Can't Deliver. Unlock the same dual-stage injection technology used by factory teams.

It’s Not About "More Fuel."
It’s About Density.

Most riders think adding a second injector is just about dumping more fuel. They are wrong. At HP Race Development, we have proven on the dyno that dual injection is about location, atomization, and temperature.

Superior Atomization

The 12-inch distance gives fuel time to transition from liquid to gas before combustion, ensuring a cleaner, more complete burn.

Charge Density

The phase change from liquid to gas pulls heat out of the intake air, creating a dramatically denser, more powerful charge.

Massive Top-End

We've seen gains of up to 2 horsepower on the dyno. That's more than most pipes and cams combined.

"I've tested every pipe on this bike... tested all sorts of ports and cams... not a single one of those items will do a two horsepower difference. Dual injection works."
— Derek Harris, HP Race Development

The "Robot Arm" Effect

1

Low RPM / Initial Throttle

The system utilizes the stock (close) injector to ensure instant throttle response and connection to the rear wheel. No lag, just snap.

2

High RPM / Wide Open

The GET ECU automatically blends in the second (far) injector. This gives you the power benefits of a remote injector without the usual hesitation of moving fuel back.

Frequently Asked Questions

When combined with the compatible GET ECU, the installation is straightforward and plug-and-play. The kit comes with a manual and all necessary brackets.

If you only run a 'far' injector, you lose throttle response. It takes roughly three engine cycles for fuel to travel from a far injector to the cylinder, creating lag in technical terrain. Our dual system solves this by using the stock injector for transients and the second injector for power.

No. The beauty of the GET system is the ability to use map switches. You can toggle between maps on the fly—comparing single injection vs. dual injection directly on the track.
