All -

So this coming week I'll be pulling apart and cleaning the carbs on my
Honda Shadow Spirit. I have the Haynes manual and have pulled apart carbs
(albeit slightly simpler) before so I'm not totally in the dark here.
I'll have access to a full machine shop (father's) while I do this so it
ought to be fun and trouble-free (famous last words).

In the Haynes manual it refers to pulling the plug for the pilot screw (I
take it the plug covers the screw? Anyone know why?) and then replacing
the plug with a new one since to pulling the old one requires drilling it
to get a grip. Fair enough.

So I'm looking at the parts fiche on bikebandit.com for the carburetor
(component parts) and I can't for the life of me figure out what part is
the plug for the pilot screw. I think it's number 5 but I'm not quite
sure and I want to make sure I have all the right bits before pulling
apart the things.

If anyone can point me in the right direction I'd appreciate it.

Thanks,
Justin

Don't bother replacing the plug. It's just a little aluminum cap that
keeps you from adjusting your idle mixture screw. It's commonly called
an EPA anti-tamper plug. Hondas sold in other countries don't have these
plugs because they aren't subject to our EPA rules. It's not a necessary
functional part of the carb in any way.

If you aren't the original owner or if you've ever had the mixture
adjusted to compensate for an aftermarket exhaust, the plugs are probably
already gone anyway,

Ah, thank you. Also . mentioned the same thing. I had suspected as much.
I am the original owner of the bike so the plug will probably still be
there.

Thanks again to both responses.

Honda : VT1100C2 A (02) MOTORCYCLE, USA, VIN# 1HFSC430-2A200001 TO
1HFSC430-2A299999

5 SKU: 16016-MAH-670
SCREW SET (Honda Code 4523783)

All the parts in the little box #5 are the idle mixture screw
assembly, which includes the idle screw, the spring, small washer,
tiny o-ring, and the EPA anti-tamper plug.

There's no point in ordering $30 worth of parts to get the little
aluminum cap that knowledgeable tuners drill out and throw away.

You probably don't need to order those parts at all, the only thing
that could possibly go wrong is a previous owner broke the tip off the
idle screw or squashed the o-ring absolutely flat.

As Marks said, the plugs shouldn't go back in.
