DescriptionThe whole story

The JP MJ 008 improves the GSX-S1000S Katana's throttle response and smoothness, which is the manufacturer's claim in full and a considerably more honest one than most.

A Name From 1981

Suzuki revived the Katana on the GSX-S platform with folded-paper styling. The engine and its mapping are shared with the roadster.

Constant Throttle Surging

A lean cruise setting produces a slight hunting at steady speeds that riders learn to ignore. It is the most common complaint about modern fuel injection and it is the thing a fuel module is best placed to address.

What Changes at the Bottom

The first eighth of throttle travel is where a lean map shows itself, as a hesitation or a jerk when picking up drive. That transition is where a module earns its money on almost every motorcycle.

Two Hundred Grams and a Cable

That is the entire physical product. The engineering is in the curve and in the harness, neither of which is visible when the seat is off.

The Contents of the Package

A module and a harness cut for one motorcycle. Everything else is the owner's, which keeps the price where it is and the fitting as short as it is.

Sequence With an Exhaust

Fit the silencer, ride it, then fit the module. Two changes at once tell the rider nothing about either, and the exhaust is the one that moves the mixture furthest.

Why Not Simply Adjust the Fuel Screw

Because there is no fuel screw. Injection removed every mechanical adjustment a carburettor offered, and everything that used to be a screwdriver job is now a decision made in software.

Why Response Is Not Power

Two motorcycles with identical peak figures can feel completely different because of what happens in the first fraction of throttle travel. That difference is worth more on a road than ten horsepower at the top.
