1. Keihin 655-A on 1972-75 Z50A
2. 1974-75 Z50A carb kit, missing the drain plug o-ring and jet pad disk.
3. 1970-73 Z50A carb kit also had a float seat and a float seat washer.
3. 16010-114-004 gasket set 
4. 16015-114-004 drain screw for 1970-73 Z50A

 

Flange Mount: 32mm hole spacing, no o-ring groove on carburetor. Instead the o-ring groove is on the intake manifold. Since the 2 x 18 (22 od) intake o-ring is not part of the carburetor, it is not in the Honda gasket set 16010-114-004, or the multi-app set 16010-114-305.

Main Jet: This carb has a “long” press-in jet, with a rubber pad disk under it.

Pilot Jet: The idle jet is not replaceable. It is inside the upper end of the brass tube, pressed into the main body, on the engine side of the main jet.

Float Seat early: The 1970-73 carburetor had a screw-in float needle seat, that was replaceable, like in the illustration.

Float Seat late: The 1974-75 carburetor did not have a replaceable float needle valve seat. The seat was part of the main body, and must be cleaned and polished with a spinning Q-tip.

Float: no-stirrup metal-tip needle valve, swinging float 16013-114-004

Top Cap: M18 x 1.0 thread

Drain screw: 1970-73 chamber set 16015-114-004 had a M4-0.7 thread drain screw with a 2 x 4 (8 od) o-ring. 1974-75 had a M6-0.75 thread drain screw with no o-ring. 1976-78 had a M6-1.0 thread drain screw with a 2 x 2.5 (6.5od) o-ring. 1979-later had a 1.5 x 4 (7od) drain screw o-ring.

In 1979 the model name changed from Z50A to Z50R, and the name Mini Trail was dropped.

2. 1976-78 Z50A carb kit D348 thick needle, #58 push-in jet. The drain screw and jet support pad are missing.
3. 1979-81 Z50R carb kit D117 thin needle, #58 screw-in jet. Left to right: drain screw, needle jet (emulsion tube), idle air screw, idle speed screw, float needle

 

Flange Mount: 38 mm hole spacing 1976-78.  32 mm hole spacing 1979-87.

Pilot Jet: The idle jet is not replaceable. It is inside the upper end of the brass tube, pressed into the main body, on the engine side of the main jet.

Main Jet:  For some reason in 1979 Honda wanted to make their jets tamper-proof. It’s funny that they went from one extreme to the other, from jets that fall out too easy, to jets that never come out. Both the NC50 and the Z50 changed to “fixed” jets (not replaceable) in late 1978 and 1979. After 1981 the jet was a screw-in, thankfully, like in the illustration

Float Seat: This carb does not have a replaceable float needle valve seat. The seat is part of the main body, and must be cleaned and polished with a spinning Q-tip.

Carb Kit: Beware of low-cost carburetor kits. In the kit at the right several things are wrong or made badly. 1) it is missing the press-in jet pad disk, 2) the jet o-ring was too big to allow the jet to press in. You can see it seems big in the photo. It was size 1.5 x 4 instead of 1 x 3, 3) the float needle was longer than stock, and the wire stirrup was bent badly in two ways. The throttle (jet) needle was D117 thin instead of D348 thick.

Float: In 1979 the float and float needle changed, from stirrup-type needle valve with black foam float, to no-stirrup needle valve 16155-883-005 with white plastic float 16013-147-004. Like before, the float needle has a rubber cone upper tip and a spring-loaded lower tip. 

Float Bowl: The 1979-later float bowl no longer has a press-in jet support pad disk 7.5 x 1.8mm.

4. CRF50F carb. The gasket for this was in use for over 34 years!

In 2000 the Z50R was replaced by the XR50R. The PA03N-A carburetor became PA42A-C, but only the needle jet and the idle air screw changed.

In 2004 the XR50R was replaced by the CRF50F. The PA42A-C carburetor did not change until 2006.

2006 was the last year of CRF50F in the US, but in Europe it continued up to 2011.

Flange Mount: 32mm hole spacing

Main Jet: screw-in #58, M6-0.75

Float: no-stirrup type white plastic 16013-147-004, needle valve 16155-883-005

Top Cap: M20-1.0 thread

Idle Mixture Screw: For the entire Z50A, Z50R, XR50R, CRF50F year range 1968 to 2006, the idle mixture screw was an air type, not a fuel type. An idle air screw blocks an air tunnel, so tighter is less air (richer). An idle fuel screw blocks off a fuel tunnel, so tighter is less fuel (leaner).

Service: Here is a good article about how to remove and clean the non-replaceable idle (pilot) jet.

https://thumpertalk.com/forums/topic/1047667-clogged-pilot-jet-on-a-crf50-success/

The CRF50F idle jet in that article did not crush when gripped lightly with a vise grip pliers. But some pressed-in idle jets have thin walls, or have a tighter fit that needs heavy clamping. Those require a close-fitting drill bit or solid wire, be placed in the hole first, to prevent crushing the tube with the vise grips. It’s a good idea to do that always.

19.  Float needles (valves)

Baby valves: These are the float needle valves for the smallest “baby” Keihin carburetors. Most other float needles are bigger than these, but look the same in photos.

Valve seats: The seat is the hole that the needle tip seals against. These “baby” Keihin PA series carbs have non-replaceable valve seats. Most motorcycle carburetors have replaceable float valve seats that screw in or push in. The seat is normally replaced with the needle. With these the seat must be cleaned, polished and inspected. It’s a tiny round hole at the end of a dark small round tunnel. It’s hard to see. It must be perfectly circular with no nicks or scratches on the edge of the hole, where it seals against the rubber cone tip of the needle.  The walls of the tunnel must be clean, smooth and shiny or the float might stick open a little and cause an overflow leak.

Beware of low cost float needles (valves). These have to be made precisely the same as originals in order to function properly. In the photo, the left one is a 16011-991-741 generic low-cost replica, made incorrectly. The stirrup wire is bent and the needle is longer. The right and middle are 16011-991-741 Honda originals (or KL-made replicas) for comparison, made correctly.

20. Float Bowls for “baby” Keihin

Here the chamber sets from above are all listed together, along with the carbs and bikes they go on. A chamber set includes the float bowl, float gasket, drain screw, and drain screw o-ring. As a courtesy, here are the links to CMS in Netherlands where you can view their image and see their price and availability.

Families: A chamber set family is one or more chamber sets that can interchange.

Jet pad: Before about 1980 these carburetors had push-in main jets. The push-in main jet was supported by a pill size rubber pad. The jet pad was held by a circular wall in the bottom of the float bowl. You can see that in the image on the right. The second bowl is for a jet pad, but the first bowl is not.

Choke jet: Carbs with fuel enrichment  type chokes have a jet in one corner of the float bowl (2nd, 3rd, and 4th in the image). Carbs with air valve choke plates do not have a choke jet (first in the image).

21.  Gaskets

There are 100’s of vintage Honda carburetors. Many share the same gaskets, but have maybe one or two things different. To reduce the number of different gasket sets, Honda combines several sets into one multi-set. In a multi set there are extra “optional” gaskets, that may or may not be needed. These are in separate packages labeled A or B. There is a sheet of paper with a table of replacement gasket set part numbers, the specific part numbers they replace, and a number, usually 1 or 0, in the A and B columns, telling how many of each “optional” gaskets are required.

Late PC50: In 1973 the PC50 carburetor changed from “donut” float to a swinging float, and a NC50-type float bowl and gasket. The 1973-77 PC50K1 and 1973-78 PF50 engine and carb are the same as the Taiwan remake engine and Keihin carburetor used on the 1978-83 Indian moped. So the carburetor parts are the same also, with some exceptions.

PA 00A (16100-081-024) and PA 01A (16100-099-693) have the same parts. The push-in jet size, venturi size and intake flange o-ring are the only difference. 

PA M0A (E210-20-50) has the same parts as PA 00A and PA 01A, except for 1) a screw-in jet instead of push-in, 2) no jet pad, 3) no jet pad holder in float bowl, 4) a white regular type float instead of a black stirrup type. 

Flange Mount: 32 mm hole spacing, 2 x 18 (22 od) o-ring 00A, 01A.

Indian AMI50: The Indian AMI50 Chief four stroke moped engine, OHV with pushrods and internal pedals, made from 1978-1984, is a Taiwan-made copy of a Honda PC50K1 or PF50 engine, OHV with pushrods and internal pedals, made from 1973-1978. The Indian had three different carburetors, Tillotson (some 1978), Keihin (some 1978, most 1979-80), Mikuni (some 1980, all 1981-84). Only the Keihin parts are listed here.

Choke plate: These three carbs have a lever choke that swings a plate to block air flow. There is no enrichment fuel path or jet. So the float bowl has no choke jet. The other baby Keihins with cable or vacuum operated choke do have a choke jets in their float bowls. The choke (enrichment) fuel passes up through the sealed off corner of the bowl gasket.  

Float Bowl: The PA-03A and 03B chamber set (float bowl, float bowl gasket, drain screw and drain screw o-ring) from 1970’s Honda mini-cycles (Mini Trail or Monkey) interchanges with a PA 00A, 01A chamber set  from 1970’s Honda mopeds. The drain screw (4 or 6 mm) and its o-ring (2×2.5 or 1.5×4) are different. So if the float bowl is changed the drain screw must also be changed. 

Needle jet: The PA-03A and 03B mini-cycle needle jets (emulsion tubes) interchange with PA 00A, 01A, and M0A moped ones. These press out with taps from a hammer and punch from above. At first the punch tip needs to be bigger than the 4 mm tube end. Once the tube end gets below the floor a smaller 3.5 to 3.9 mm straight round bar is needed. It has to enter the 4 mm hole and contact the idle tube around the edge.

Idle jet: A little downstream from the needle jet is the idle jet. It is a pinhole 0.015″ at the upper end of a vertical brass tube about 20mm long. The idle tube is a press fit in the carb body. Some can be pulled out with just a pliers. Some might be tighter and require a drill bit be placed inside the tube to prevent crushing from the tighter pliers grip. This tube was never intended to be replaced and is not sold or included in any common carb kit. 

Air tunnels: In the front below the main air inlet are two small horizontal air tunnels. The center tunnel is main air and the side tunnel is idle air. The small amount of air sucked in through the main air tunnel passes through tiny holes in the emulsion tube and becomes thousands of microscopic air bubbles in the liquid gasoline that is being drawn upward. The tiny amount of air sucked in through the idle air tunnel passes around the idle air adjustment screw cone shape tip and goes to the vertical idle passage just above the idle jet. The idle air tunnel is the size of a regular paper clip 0.036 inch. A straightened paper clip cleans it perfectly.

Honda’s successor to the four-stroke PC50 was the two-stroke PA50, known in the USA as Hobbit, and in Europe as Camino. It was made in Belgium by Honda Benelux, so it had a mix of Japanese and European design and componentry. 

In US models, 20 mph versions were 1978-79 red. 30 mph versions were 1978-79 yellow, 1980 yellow, 1981-82 red, and 1983 black.

This Keihin BB type carburetor is not like any other moped carburetor. It looks more like a Honda generator carburetor. It is a very flat design. It has to be special because it swings up and down with the engine, and is very close to the frame at the place where you step through.  The BB type floats on PA50 are wider and flatter than NC50 or Z50 floats.

 Servicing: The best way to remove the PA50 carburetor is to hold the back of the bike up by either a rope tied to an overhead beam, or with a milk crate and blocks of wood. Remove the floorboards and side covers. Unplug the ignition wires from the coil at the right rear. Pull them through and move them out of the way. Disconnect the decompression cable and the spark plug cap. Loosen the wiring clamps so there is slack in the wires. Remove the lower rear shock bolts and the swing arm pivot bolt above the engine. Then the whole sub-frame can be moved away from the main frame, either by lifting the back of the bike up, or by swinging it around sideways.

Note that the float bowl can go on two different ways. The wrong way assembles normally, but causes the vertical brass overflow tube to contact the float. Honda designed all of the cleaning ports, drain screws, and adjustment screws to face the right side of the bike, which is the upper left in the exploded view. The drain hose spigot on the float bowl faces the same way as the adjustment screws. The other way to tell is by shaking the carburetor. If you can hear the float rattling inside then the float is not stuck so the float bowl is on correctly. 

While every other moped carburetor is a sliding throttle valve type, this one is a swinging plate throttle valve. The reason is to be flatter, to get more clearance from the bottom of the frame. The manual choke is also a swinging plate, with an automatic release.

Some servicing can be done with the carburetor installed. It is easy to clean the idle passages and jet by spraying a one second long burst of carb spray into the idle mixture screw hole, followed by compressed air. The running engine is allowed to consume the flammable solvent before the next burst is sprayed in, to prevent the engine from getting flooded.

2. Keihin

4 or 5: In this Keihin carb family the second digit of the model name is either 4 or 5. That tells the speed and power version. 4 means 40 km per hour. 5 means 50 km per hour. Each country has it’s own speed limits and safety requirements.

9 or 10 mm: “4” carbs for 40 km/h bikes are size 9 millimeter. “5” carbs for 50 km/h bikes are size 10 mm.

1969-70 PC50: Before April 1970, the PC50 had a OHC engine (over head cam). The valves were operated by a cam in the head, driven by a cam chain.

Spigot mount: The Keihin C4A, C5A, S4A, S5A, C4B, C5B, S4B, S5B carburetors were spigot mount type. They had a round float bowl gasket (with three flat sides when installed), a push-in jet, jet pad, completely round “donut” float, all metal float needle with replaceable float seat.

1970-73 PC50K1: After April 1970, the PC50K1 had a OHV engine (over head valve). The valves were operated by pushrods from a cam down in the case.

Flange mount: The Keihin F4A, F5A, carburetors for the 1970-73 PF50 were flange mount type with 32mm bolt spacing. There was a diamond shaped gasket rather than an o-ring like all later flange mount carbs. Everything else was the same, round float bowl gasket (with three flat sides when installed), a push-in jet, jet pad, completely round “donut” float, all metal float needle with replaceable float seat.

1.  Type B Controls

Domino “80’s black” controls were on 1980’s and 90’s mopeds. In the US they were on ’83-86 Trac, ’86 Garelli, and ’86-91 Tomos. The lever blades are black plastic. The cast aluminum housings are black, and have a large empty space for integrated CEV or CEV-compatible switches. 

Here is how they look with switches installed. These are Trac switches, not CEV.

Domino 80’s black controls (bottom) compared with 90’s HR Hidria Rotomatika (top) controls used on ’92-07 Tomos. They look the same but almost nothing interchanges. HR switches do not fit Domino and CEV switches do not fit HR.

Brake light switch holes: All type B controls have threaded holes for a brake light switch.

Throttle assist spring: All type B right controls have a throttle assist spring.

2.  Type S Controls

Domino “late Solex” controls were on 1986-88 S 3800 made in France by Motobecane (at right), and the re-make of that, 1999-2005 Solex 3800 made in Hungary by Impex (at left). The throttle is self-closing, unlike most older Solex’s. What’s special is the front (right) brake also controls the throttle (gas). So it has an “either or” mechanism.
