The Sensible Middleweight
Yamaha's 600 cc four detuned heavily for the road, sold in enormous numbers to riders who wanted something dependable and unexciting.
With an Aftermarket Exhaust
A freer silencer changes what the engine can pass and the standard controller can only compensate so far. This is the commonest reason owners look at a fuel module, and it is the situation where the difference is most obvious.
Under the Seat
That is where most owners put it, because it is dry, out of sight and close to the injector harness on the majority of machines. A cable tie and five minutes of thought is the whole of the installation advice.
Small Openings Matter Most
Almost all road riding happens in the first quarter of throttle travel. A change there is felt on every corner exit and in every roundabout, which is why response is a better sales argument than peak power.
Consumption, Honestly
No meaningful change either way. Anybody who reports a large difference has changed their riding at the same time, which is what usually happens after fitting anything to a motorcycle.
At Resale
Off in minutes, into a box, and the motorcycle is standard. Or left on and mentioned in the advertisement. Neither choice damages anything.
A Second Opinion Worth Having
Ride the motorcycle for a week paying attention to the first eighth of throttle travel. If nothing about it irritates, the honest answer is that this module has nothing to fix.
Six Cylinders
At the other extreme, an inline six is so smooth that a lean patch is easy to miss. The correction still applies; the rider simply has less to compare it against.
