I have one-all I know is that there is a big canister under the injectors for evaporative emissions (I think), more tubing and a solenoid that I would love to trash but don't know if it affects the ECU or whatever?? Dev says leave it alone as it does not affect the running of the engine which runs like a bullet train by the way. I still want it gone. I do not know how these bikes are ID'ed-prob through the SN.

HiVel,
The cannister is just an overflow from the fuel tank that catches the fuel and evaporates it into the airbox instead of letting it drip on the ground. Just like in many cars.

If you want to remove it, it is easy, and the ECU won't care. Unplug the servo from the harness, route the vacuum line from the throttle body to the MAP sensor on the tank, and remove the cannister hardware. Keep it - you might be able to sell it to the CA owners buying a new or low mileage bike from out of state.

The canister has a solenoid. I installed a non-SAI tune before unplugging mine so I'm not sure if unplugging the canister's solenoid will give a CEL. If you decide to get rid of the SAI system, make sure to get the bike tuned by a pro so they can get the A/F ratio dialed in. With the right A/F ratio, you should have better emissions than the bike in stock form. Plus, you'll get better fuel economy.
