Re: Motorcycle Fuel Management Systems

See ASA Guideline 2b Chapter 4.8 https://asa.ch/it/biblioteca-online/direttive/

In general anything which may change noise, power, and exhaust emmision needs approval and you must show that you are still within the limits set by the law relevant for your vehicle.

In conclussion with the right papers you can do chiptuning and use power comander, dyno jet etc. If the right papers are available is another question.
Static chip tuning should be easy, adjustable and dynamic stuff such ans power commander, dyno jet etc. is most likely out of scope.

If you simply replace your existing foam or paper filter in the airbox with a K&N then I do not see any issue. If you remove the airbox and put a "mushroom" filter at the inlet of the throttle valve body/carburator then you most likely must show and proof that you are still witihn the limits.

PS: It is your duty to show that your bike is compliant in case it has such modifications. It is not their duty to show that it is non compliant. It is by default non compliant until proofed otherwise.
