DescriptionThe whole story▼
The JP MJ 003 is fitted to the Sportster 883 Superlow XL883L to make an injected engine pleasanter rather than faster, and the description says exactly that.

The Evolution Engine
Harley's air-cooled 883 cc vee has been in production since the nineteen eighties. Its injection was added late and mapped conservatively for emissions.
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.
On an Older Motorcycle
Early injection systems were mapped more coarsely than current ones and frequently ran leaner. A module tends to make a bigger difference on a machine from the two thousands than on one from last year.
Model-Specific Wiring
JetPrime supplies the harness for the chosen motorcycle with the correct connectors moulded on. It is the part of the product that costs the most to develop and the part nobody thinks about.
Not a Season-Long Project
Some tuning components lead to a winter of adjustment. This one is fitted in an afternoon and then behaves identically for the next decade.
How Long It Takes
Between twenty minutes and an hour depending on the model. The variable is access to the injector harness and nothing else about the job changes.
The Cable Tie Matters
A harness left loose eventually finds a moving part or a hot one. Thirty seconds securing it properly is the difference between a component that lasts a decade and one that fails in a wet autumn.
Where the Development Happens
JetPrime works the curve out on their own equipment for each engine family. That is invisible in the product and it is the entire reason a preset module can work at all.
