Fuel booster plug – Yamaha FZ-07 / MT-07 / Tracer 700 / XSR 700


Do you find your bike prone to stalling at low engine speeds, lack of throttle response and a lumpy feel to your motor?

Have you fitted a free flow exhaust and worried about it running too lean?

Then this plug and play device will resolve these problems without the need to re-map you ECU.

Fits Yamaha FZ-07 / MT-07 / Tracer 700 / XSR 700.

Modern EFI bikes especially Euro 4 run very lean in open loop mode and this can cause stalling, poor running and hesitant acceleration.

This fuelling device interrupts the signal from the air temp sensor and modifies it to make the ECU add approx 4-6% more fuel during acceleration in open loop mode, it will not affect MPG as it has no effect in closed loop mode ie. cruising mode or steady running. The device has its own temp sensor and it modifies the signal to release the correct amount of fuel for the measured air temperature.

Totally agree with the last guy. This thing completely tranformed my 2022 MT07 in exactly the same way. A must have upgrade for sure.


This little device changed my bike. Eliminates the anarchy throttle at low RPMs. Can’t believe what a difference it makes to the way my bike feels. I cannot recommend this high enough.

Performance upgrade

I recently purchased the performance exhaust for the XSR700 from tec bike parts and decided to fit the fuel booster plug along with the DNA high flow air filter.
I wasn't disappointed with the results.
A massive improvement from the stock set up.
Totally changed the bike.

Great product and service

Ordered a booster plug and DNA filter for XSR 700. Makes a big difference to the overall throttle response. Smooth low down power with no more jerky throttle response but a little more stream lined power throughout the range. Very helpful sales staff, great product.

Transformed the bike.

Fitting the Booster Plug has completely transformed my MT-07. Engine braking and acceleration are much smoother, throttle response is much more predictable and the average mpg has increased. Brilliant piece of kit.
