Not sure this is translating good enough for members to know what you are asking. My guess you are asking about the Evap Canister or maybe this one from another forum Canisterectomy
It might help to post your questions in both Italian and English. Someone who reads might not completely understand the English translation but might understand the native Italian language. Not me, I'm afraid, but there must be at least one person in the forum who's got some native italian speaker in their household.
He's asking about the air injection into the exhaust to burn excess hydrocarbon. I've not looked at it on this bike. However, it really doesn't affect performance as far as I know. It does cause some back firing or burbbles from the exhaust.
Scusatemi io non parlo bene inglese e il traduttore in effetti traduce alla cazzo di cane ha ha ha ... il senso della mia domanda comunque l'avete capita e trovo utilissimo il vostro thread sull'argomento. I'm sorry I do not speak English well and in fact the translator translates the f**king dog ha ha ha ... the meaning of my question though you have understood and find it very useful on your thread on the subject.
Post combustion air injection is not parasitical. You will not gain any HP by removing or plugging the port. Waste of time and not good for the environment either. Cheers
