Usually this will be on a CA bike with all the emissions crap strict laws. Remove all that and install block off plates.

Indeed. That stuff is only on the California bikes on the Gen 4. All G5s have them though. If you have it, then you have a Cali ride. It can be removed as Belkins described.

Doesn't hurt performance at all.

The block off plates are something different then what you
are looking at.

What you are looking at is a simple closed loop system
for fuel emissions.

That's the charcoal canister that's tied into the
gas tank and back into the fuel system allowing
fumes to either be filtered out through the canister or
recirculated back into the fuel system.

The only by product of removing would be venting
your gas tank directly into the air, possibly extra gas
fumes in the garage.

The positive is a whole pile of hoses and crap removed.

Since there is no emission testing you could remove.
Normally removing canister would cause a failure of
emissions testing.
