The charcoal canister is an emissions piece and can be the source of hard starting (do a search for more info--lots written about it).
Most dealers won't remove it, so if you want to do it you'll have to do it yourself. Not many mods are easier than this, so long as you know which line to cap and which to vent.
1) Remove your upper and lower right side fairings, which will expose the canister.
2) Undo the rubber strap holding the canister to the bike, then remove the top two hoses (cutting off with scissors works if you don't plan on ever installing it again).
As in the picture, one of the lines leads from the gas tank to the canister and the other leads from the canister back up into the intake:
3) The line from the tank (which has a larger inside diameter than the vacuum line in case you cut both lines and now can't figure out which was which) needs to be extended using about another 12" of hose and a hose barb and routed to a safe place (read: far away from your headers/exhaust!). I removed the hose from the bottom of the canister and used this to extend the fuel vent line, which was conveniently just the right length. Route it wherever it's safe to route it, as gas/gas vapors will be escaping from this line. Make sure it's not blocked, kinked, smashed, or plugged with the bodywork back on.
4) Plug the vacuum line (which has a smaller inside diameter than the vent line). You can cap it with a hose cap, fold it and zip tie it tightly, or shove an M4 screw into it and zip tie it (which is what I did).
5) Remove the charcoal canister bracket by unscrewing the three screws marked in the pic below.
Finished (plugged line is hidden):
While you're at it, make sure the other fuel vent line (the one in the far right, closest to the front wheel, running vertically down) is not pinched or kinked when you put the bodywork back on. During my last service they pinched the line and I didn't discover it until I did this mod.
