I just bought an s4r and would like to delete the charcoal canister. The salesman told me that it would screw up my fuel injection. I don't believe him. He was about 19 and didnt seem to know or care much about the Ducatis in the shop. He seemed more into the other japanese brands they sold. Is this so? If not is it just a matter of rerouting the vent lines out the bottom of the bike next to the other vent lines? Or is there much more to it than that.
