DescriptionThe whole story▼
The JP MJ 017 answers the flat spot a lean cruise setting gives the Leoncino 500 Trail, and does it without disturbing ignition timing or any rider aid.

- Unplugs at any time, nothing is written to the motorcycle
Scrambler Clothing
Spoked wheels, block-pattern tyres and a higher bar. The Trail is the same 500 twin dressed for a photograph on a gravel track.
The Loom Is Model Specific
The module is common; the harness that connects it is not. JetPrime supplies the wiring for the chosen motorcycle, which is why the catalogue lists machines rather than engine sizes and why a part from another model is not a shortcut.
Smoothness Is the Product
Riders who fit one describe a throttle that picks up cleanly from closed and holds a steady speed without hunting. Nobody describes a hole shot. The claim and the experience match unusually well here.
A Component, Not a Project
Some tuning parts start a conversation that lasts a season. This one is fitted on a Sunday afternoon and then never thought about again, which for most owners is exactly the point.
Rider Aids Are Blind to It
Traction control reads wheel speeds, not injector pulses. Nothing about the module's presence enters the calculation for any electronic aid on the motorcycle.
When Not to Bother
A current machine with the standard exhaust that the owner has no complaint about. Fitting a correction to a mixture that is already right achieves nothing worth the money.
A Note on Dyno Runs
A power run measures full throttle from low revs to the limiter. That is one line through a map with hundreds of cells, and it is not the line this module was designed to change.
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.
