DescriptionThe whole story▼

The Faired Twin
Same 649 cc engine with bodywork and slightly lower bars. It is the sensible sports bike that a great many riders should buy and do not.
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.
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.
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.
Physically Small
About the size of a matchbox and around two hundred grams. On a motorcycle the difficulty is never the module itself, only finding a tidy route for the cable.
A Curve, Not a Setting
The correction varies with load and engine speed rather than being a single percentage. That is what separates a developed module from a resistor in a box, and it is why it is sold per model.
Two Up and Loaded
A pillion and luggage put the engine at higher load for the same throttle opening, which moves the operating point into a different part of the map and often exposes it.
What Happens at Full Throttle
The correction continues to apply, but a fully open throttle is a condition the factory maps carefully anyway. The differences there are smaller than at part load.
