DescriptionThe whole story▼
The JP MJ 008 is the simpler of JetPrime's two fuel units for the Ninja 300: a curve somebody else worked out, rather than one the owner has to develop.
Key Features
- Kawasaki Ninja 300 (2013–2016)
- Preset fuel module, no programming required
- Corrects the mixture without remapping the original electronics
- Plug-and-play with model-specific wiring
- Around 200 g, fitted in an evening
- Unplugs at any time, nothing is written to the motorcycle
The Predecessor
Kawasaki's 296 cc twin in faired bodywork was the small sports bike of its generation, and enormous numbers were prepared for one-make racing.
Response Rather Than Power
The manufacturer's claim is throttle response and smoothness, not horsepower. Anybody expecting a figure on a dyno sheet has misread the product. What changes is how the engine answers a small movement of the hand, which is where most riding actually happens.
Nothing to Service
There is no interval, no filter and nothing to inspect. The module is sealed and it either works or it does not, which after the first ride it demonstrably does.
What Comes in the Box
The module and the model-specific harness. Cable ties, a place to put it and twenty minutes are the owner's contribution, and nothing else is needed.
What It Will Not Do
Raise a rev limit, alter ignition, change a rider aid or repair a worn sensor. Being clear about that is more useful than a longer list of what it does.
Why Any of This Is Necessary
Emissions regulation has tightened faster than engines have changed, and manufacturers meet it partly by running lean where the test looks. The consequence is felt by the rider rather than measured by the laboratory.
Commuting
Stop-start traffic is the opposite case. Every junction is a transition off a closed throttle, which is exactly the region where a lean factory map is most obviously lean.
Fitting It in Winter
There is no reason to wait for good weather. The job happens in a garage, needs no test ride to complete and the result is available on the first dry morning.
