Apologies for my lack of knowledge but what exactly is this part? (see circled part in pic)
That is the charcoal canister which collects all fumes from the engine and fuel tank breathers redirecting them back in through the airbox to be burnt as part of the combustion proccess. They were mainly fitted to Californian bikes but now they all come fitted with them and they are mounted on the right side of the oil cooler on later models and covered with a cowl that resembles the one on the left.
They don't really add anything but many areas forbid venting to atmosphere. Instead of venting to atmosphere the fumes go through a charcoal canister and then get burnt. the theory is that all combustible fuel and vapours get burnt creating less raw emissions.What do they add (to performance? )?
Has my FTP got one?
