I wish to remove the canister under the left side cover to make room for a Stebel Nautilus Horn.
I found a wad of hoses connected to the canister and wish to be sure I remove, plug or reroute the correct tubes.

Has anyone else done this on a Roadster that would be willing to provide me some assistance?

Essentially you need to block the circled pipe 'b' hose where it fits onto the Purge Control Valve and also the Pipe C hose

Or - if you really want to clean things up, you get rid of all those hoses too and just fit blanking plugs on all of the nipples on the TBs end

p.s. Still waiting for picture from you!

Ken,
Thank you SO MUCH for that awesome diagram!!!
So then, plug or remove and plug throttle bodies for "B" and "C".
What to do with "A"?
 
Leave the hose from tank to rollover valve connected then hose from other end of rollover valve just vents to ground
ie just disconnect it from canister (or replace that section if needs to be longer)

Do you need to run a new drain hose from the gas tank to an exit point under the frame somewhere, or is it just a vapor purge system?

Great idea there, I'm thinking about making that a winter project.
Doing this won't throw any codes on the ECM?
 
I had this system removed from a TBird. Pipe A should be extended to vent under the bike without the rollover valve, which, being a valve, could close or get plugged. Otherwise, cap the inlets on the TBs and rip everything else out. I believe there were one or more electrical connectors on the purge valve or cannister. Note sure what they did with those but had no effect on the ecu.
 
The Purge valve connector being disconnected will not throw an MIL error.

The line to the Roll-over valve is the tank vent - it should normally not be flowing gas down to it - except in the event of a 'roll-over' (duuhhh!)
You can take the Roll-over valve off if you choose, however you should leave it in place for its intended purpose, which has nothing to do with the emissions, but to prevent gas spillage if the bike goes down.

And it worked like a charm too!
Now when the pins get here I'll get er running.
