DescriptionThe whole story▼
The JP MJ 004 sits between the F800GT's loom and its injectors and adjusts how long each one stays open, which is the whole of what a power module does.

- Preset fuel module, no programming required
- Corrects the mixture without remapping the original electronics
- Plug-and-play with model-specific wiring

A Sports Tourer on a Belt
The 800 twin drives through a toothed belt rather than a chain, which is quieter and cleaner and changes very little about how the engine is fuelled.
On a Machine Being Sold
Unplugging the module and putting it in a box makes the motorcycle standard again. Whether that helps or hurts the sale depends entirely on the buyer, which is an argument for keeping the original connectors in good condition.
Vibration and Water
The module lives on a motorcycle and is built accordingly, sealed as a unit and secured rather than left hanging. Neither is remarkable; both are necessary.
The Case Against Buying It
A late model motorcycle with the standard exhaust, ridden gently, is already mapped about as well as it needs to be. The honest advice there is to spend the money on tyres.
Who Should Not Buy One
An owner with a standard exhaust, a recent motorcycle and no complaint about how it runs. There is no reason to fit a correction to something that is already correct.
At Resale
Off in minutes, into a box, and the motorcycle is standard. Or left on and mentioned in the advertisement. Neither choice damages anything.
The Question to Ask Yourself
Does the motorcycle irritate at small throttle openings? If the answer is yes, this is the cheapest thing that addresses it. If the answer is no, nothing here applies.
Popping on Overrun
Some of it comes from the emissions hardware in the exhaust rather than from the mixture, so a fuel module reduces it in some cases and not in others.
