Prices and sources may vary depending on when you read this. I
get lots of questions about the best carb repair kits. Here's
some information detailing what's in popular kits. The "best"
kit will depend on what's actually needed for your particular
overhaul.
1.
If your carbs only need cleaning and new o-rings, and you don't
need to split the carbs from the plenum and you don't need new
jets or needles...
a
good option is PartsNMore.
These
kits contain:
O-rings:
-
primary main
-
secondary main
-
float seat
-
idle mixture screw
-
bowl drain screw
-
intake manifold
-
carb to plenum air o-ring
Gaskets:
- fuel
bowl gasket
-
special gasket for the kidney shaped plate over the air jets
Hardware:
- aftermarket
float needle and seat assembly
Note:
the float needle and seat assembly is an aftermarket unit and
unreliable. Aftermarket float needle and seat assemblies DO NOT
include the very important fuel inlet screens. You should examine
and reuse the OEM Honda float needle, seat assembly and inlet
screen if possible. Otherwise, go with new OEM Honda float valve
assembly.
Note: As mentioned, this kit includes the carb to plenum air O-ring
but does not include the special carb to plenum fuel o-rings,
so this kit alone is not sufficient if you intend to split the
carbs from the plenum.
Note:
Does not include the special gasket to join the 2 halves of the
plenum. This OEM item is available only from Honda (or
Randakk). List Price..about $28..internet price from
various sources is about $20.
This
kit is sourced from Tour Max, which is made by Keyster.

Price
is $10/carb which is a fair bargain.
Curiously,
they also sell the aftermarket float needle and seat assembly
separately for $8 each.
You
will also need:
-
They sell the 4 rubber passage plugs that cover the idle jet...package
of 4 for $6.
-
They sell the air cutoff valve kit for $12.00 (good price)
2.
Another option, if you decide you only need o-rings:
is
the Classic Wing Club: http://www.classicwingclub.org/ Sporatically
available from their classified section:
Carburetor
O-ring Sets
One
set will do all four carbs.
Three
different sets now available.
Small
set: $10.00 + $3.00 S/H
Large
set: $35.00 + $3.00 S/H
Intake
Manifold only:$8.00 +$3.00 S/H.
I'm
not sure what's in the small set, but the Large Set is the one
you will need. It includes internal and external o-rings for 4
carbs.
Also
includes:
CWC
Large O-ring Kit does NOT include:
- float
bowl gaskets
- air
jet cover gaskets (kidney shaped gaskets)
- carb
pucks
- 4
rubber plugs which cover the idle jets
-
fuel bowl gasket
-
special gasket for the kidney shaped plate over the air jets
-
special gasket to join the 2 halves of the plenum. This OEM
item is available only from Honda (or
Randakk). List Price..about $28..internet price from
various sources is about $20.
- Air
cutoff valve overhaul kit
- 1
mm cotter pins for linkage
- "E-clips"
(required for '75 linkage)
-
5 special screws and lock washers in 2 lengths to re-join the
plenum halves
- fuel
filter
Curiously,
this kit also includes one extra O-ring which I believe is intended
to be the "bumper" gasket which goes under the carb top. Not a
seal per se (the carb top is self sealing), the OEM item is a
flat plastic ring which limits the downward motion of the vacuum
slide. Since, the OEM ring rarely wears out you should reuse the
OEM item and toss this extra O-ring
I'm
not keen on this kit. The parts are fine. My problem is all the
necessary items which are left out. Just one example, you would
never want to reuse old float bowl gaskets. Buying this
kit might temp you to make such a choice.
3.
If you need a comprehensive kit, including o-rings, gaskets and
jets...
a
good option is Sirius
Consolidated.
In
the "Carb Kits" section they sell comprehensive kits (sourced
from NAPCO and Keyster) which include:
O-rings:
- primary
main
-
secondary main
-
float seat
-
idle mixture screw
-
bowl drain screw
-
intake manifold
-
carb to plenum air O-ring
Gaskets:
- fuel
bowl gasket
-
special gasket for the kidney shaped plate over the air jets
Hardware:
- aftermarket
float needle and seat assembly
-
6 jets
-
primary main fuel jet
-
secondary main fuel jet
-
idle fuel jet
-
primary air jet (size not marked!)
-
secondary air jet (size not marked!)
-
idle air jet (size not marked!)
-
idle mixture screw and spring
-
jet needle for carb slide
-
grub screw for jet needle
Note:
the float needle and seat assembly is an aftermarket unit and
unreliable. Aftermarket float needle and seat assemblies DO NOT
include the very important fuel inlet screens. You should examine
and reuse the OEM Honda float needle, seat assembly and inlet
screen if possible. Otherwise, go with new OEM Honda float valve
assembly.
Note: As mentioned, this kit includes the carb to plenum air O-ring
but does not include the special carb to plenum fuel o-rings,
so this kit alone is not sufficient if you intend to split the
carbs from the plenum.
In
case you need to split the carbs from the plenum, this kit does
not include the special gasket to join the 2 halves of the
plenum. This OEM item is available only from Honda
(or Randakk). List price for this special gasket is
about $28..internet price from various sources is about $20.
Also,
does not include the special carb to plenum fuel o-rings
(these are available in the Classic Wing Club "Large Set," the
OEM Honda "Packing Set" or from Randakk's.)
(For my
exclusive Carb-to-Plenum special fuel o-rings ...Click
here)
Also,
does not include the rubber passage plugs which cover the
idle jet
Caution:
the NAPCO kits contain 3 jets which are identical except for the
orifice size: idle air, primary air and secondary air jets. They
are NOT stamped with the jet size on the jet as OEM jets are.
These 3 jets come in individual plastic bags with labels indicating
the jet size. It would be very easy to screw up the placement
of these jets so be careful out there.

Retail
price for the kits from Sirius is $15.00 / carb which is a very
good value. However, in my experience, jets and jet needles rarely
wear out, so you may not need them.
Be
sure you order the correct part # for your specific year. Sirius
also has good prices on air cutoff valve kits.
4.
Another comprehensive kit, including o-rings, gaskets and jets...
another
option is Cycle Re-Cycle II: http://www.crc2onlinecatalog.com/Index_Main_Frame.htm
In
the "Fuel System Parts" section they sell a comprehensive kit
(sourced from K&L). K&L kits can be ordered from any motorcycle
dealer. These include:
O-rings:
-
primary main
-
secondary main
-
float seat
-
idle mixture screw
-
bowl drain screw
-
intake manifold
-
carb to plenum air O-ring
Gaskets:
-
fuel bowl gasket
-
special gasket for the kidney shaped plate over the air jets
Hardware:
-
aftermarket float needle and seat assembly
-
6 jets
-
primary main fuel jet
-
secondary main fuel jet
-
idle fuel jet
-
primary air jet
-
secondary air jet
-
idle air jet
-
idle mixture screw and spring
-
main fuel nozzle (emulsion tube which is hardly ever needed)
-
synchronizing screw, spring, washers and nut (hardly ever needed)
Other:
-
rubber passage plug which covers the idle jet
(In
case you need to split the carbs from the plenum, this kit does
not include the special gasket to join the 2 halves of the
plenum. This OEM item is available only from Honda (or
Randakk). List Price..about $28..internet price from
various sources is about $20).
Also,
does not include the special carb to plenum fuel o-rings
(these are available in the Classic Wing Club "Large Set," the
OEM Honda "Packing Set" or from Randakk's.)
(For
my exclusive Carb-to-Plenum special fuel o-rings ...Click
here)

Price
is $26.95/carb. However, in my experience, jets and rarely wear
out, so this is of questionable value. Also, the fuel bowl gasket
is OK but it is not cut as precisely as OEM and other aftermarket
gaskets. These K&L kits are also available from JC Whitney or
any motorcycle dealer. Be sure you order the correct part # for
your specific year.
5. OEM
Honda "Packing Sets" are very comprehensive on the rubber parts,
but contain no hardware...
O-rings:
- primary
main
- secondary
main
- float
seat
- idle
mixture screw
- bowl
drain screw
- carb
to plenum air O-ring
- special
carb to plenum fuel O-ring (hard to find elsewhere)
Gaskets:
- fuel bowl
gasket
- special
gasket for the kidney shaped plate over the air jets
Plus:
CV carb slide
top to carb body plastic "bumper" rings (only source I know of
for this particular item…these rarely wear out though).
Plus:
this kit INCLUDES the special carb to plenum fuel O-ring
.
List Price..about
$46/carb...Internet price from various sources is about $34/carb.
Not a great deal really, unless you need the special carb to plenum
fuel o-rings (If you split the carbs from the plenum, you will
also need the special gasket to join the 2 halves of the plenum.
This OEM item is available only from Honda (or
Randakk).
List Price..about $28..internet price from various sources is
about $20).
6.
If you need the float needle and seat assembly...
The only way to go is OEM Honda. These are pricey, but easily
last 25 years and 100,000 miles. Honda also includes the inlet
fuel screen with their set (very important!). I don't know of
another source for these screens. They are not available separately
and not included with aftermarket sets. Also, aftermarket float
valve and seat sets are notorious for leaking!
List
Price..about $21/carb...Internet price from various sources is
about $15/carb.
7.
If you just need individual o-rings, etc...
the
best option is Cycle Recycle II: http://www.crc2onlinecatalog.com/Index_Main_Frame.htm
Go
to the "Fuel System Parts" section ...look under the section with
the complete GL1000 carb kits for a link to "More Special Carb
Parts for Gold Wings": http://www.crc2onlinecatalog.com/gl_carb_parts.htm
There
you will find a good variety of o-rings, gaskets, passage plugs,
fuel bowl screws, etc. priced individually.
Have
you lost a small part during a carb overhaul? Need just one O-ring
or jet and don't want to buy another complete rebuild "kit?" If
so, I may be able to help. I have an extensive supply of individual
carb parts for the '75-77 GL1000 (+ some parts for later GL1000s)...
