DescriptionThe whole story

The JP MJ 004 is the plug-and-play fuel module for the G 650: a curve worked out for that engine, supplied with the harness the motorcycle needs.

  • Unplugs at any time, nothing is written to the motorcycle

A Single From Rotax

BMW's 652 cc thumper powered a whole family of machines, and its injection is about as straightforward as fuel injection gets on a motorcycle.

What a Power Module Actually Does

It sits between the motorcycle's loom and its injectors, reading what the standard controller decides and adjusting the injector opening time before the signal arrives. The original electronics keep their job and their diagnostics; the module only corrects the quantity of fuel that reaches the cylinder.

Buying With an Exhaust Already Fitted

This is the most common situation and the clearest case. A motorcycle running an aftermarket silencer on the standard map is working with a mixture the factory never intended it to have.

No Software to Learn

It is worth repeating because it is unusual: this product has no user interface at all. It is plugged in and then it is forgotten about, which is why it suits owners who are not looking for a project.

Nothing to Configure Afterwards

There is no pairing procedure, no calibration ride and no reset. The motorcycle is started and the module is already doing what it does.

The Strongest Case

An older injected engine, an aftermarket silencer and a rider who has noticed the hesitation. That is where the product does exactly what its description says.

A Second Opinion Worth Having

Ride the motorcycle for a week paying attention to the first eighth of throttle travel. If nothing about it irritates, the honest answer is that this module has nothing to fix.

A Note for Workshops

The module is visible under the seat and unplugs in seconds. Any diagnosis on the motorcycle should begin by removing it, which takes less time than reading this paragraph.
