Myrons Mopeds

and Type T Controls

 

Controls in this T family are on 2002 to 2017 Tomos mopeds, sold in the US and Canada.

 

  
Column D Tomos 2002-07 Hydraulic Front Brake Models: The first US models of Tomos Revival 2002-07, Streetmate 2005-07 and Arrow 2005 had Domino controls, made in Italy. Domino controls can be identified by the yellow horn and engine stop buttons.

 

  
Column T Tomos 2006-17 Hydraulic Front Brake Models: Later those controls were superseded by Domino clones, made in China by TBS, on the 06-07 Arrow-R, 07 Streetmate, 07 Revival and all 2008-17 models. TBS controls can be identified by the red horn and engine stop buttons.

 

 
Column T Tomos 2007-17 Cable Front Brake Models: From late 2007 to 2017 the controls on Tomos Sprint, ST and LX models were Domino clones, made in China by TBS. TBS controls can be identified by the red horn and engine stop buttons.

 

What’s the difference? The TBS control parts interchanged with Domino except for:

1) Brake light switch threads: Domino is American 1/4 – 32, TBS is metric M6-0.80.

2) Right mirror threads: Domino is M8-1.25 left hand, TBS is M8-1.25 right hand. 

3) Pivot bolt: Domino is M6, TBS is M5 with ∅6 shoulder.

4) Switches: Do not interchange.

Lost Keys on Streetmate:  The faux tank lid can bend enough to open without a key. Pull upward on the middle of both sides. Once inside the faux tank lift up the floor mat on the left side. That exposes a lot of wires and connector plugs. Locate the green connector plug. Unplug it. The bike will then kick start and run without a key. Only the headlight will operate normally. The other lights will be dim.

B. Info and Wiring

 

Please note the push button on a brake light switch is normally (most of the time) pushed in when installed. It is only momentarily released out when the brake is applied. That is opposite of most other push buttons. To avoid this source of confusion you have to add “when installed” to specify the way it functions. A normally closed switch is normally open when installed and visa versa.

 

A. Brake Light Switches

---

1. Screw-in type (European mopeds)

These brake light switches are located on the hand levers. 

Tip color: On vintage European moped brake light switches, the color of the tip tells the function. Black tip is normally open when installed. White or brass tip is normally closed when installed. 

Threads: Vintage moped controls, made in Germany by Magura and in Italy by Domino, OSL, and PV, and modern Domino controls, have “inch” threads on the brake light switch holes, ¼”- 32 tpi. A ¼” (6.3 mm) brake switch measures 6.1 to 6.2 mm at the thread tops.

Tomos TBS brake light switch, smaller, white long tip
M6-0.80 thread, normally-open-when-installed
243241  $9.00  new  (closed when button is released)
Required on 2008-17 Tomos Sprint, ST, LX, with
TBS controls (identified by red horn button). 
left only: Revival, Streetmate, Sm.-R, Arrow-R

’08-17 Tomos threads: Modern TBS controls used on 2008 and later Tomos, made in Taiwan presumably, which are otherwise Domino-compatible, have “metric” threads on the brake light switch holes, M6-0.80. An M6 (6.0 mm) brake switch measures 5.8 to 5.9 mm at the thread tops. An M6-0.80 brake switch will screw into a 1/4″-32 hole, but not visa versa. So 2008-later Tomos controls must have only that 243841 switch.

B. Info and Wiring

---

 

“normally open when installed” is also known as “on in paused position”. When the brake lever is squeezed, the switch button is not pressed (paused), and the switch is closed (on). That makes the brake light go on, because the brake switch is wired in series with the light. With two switches, they are wired in parallel with each other, and in series with the light.

With two switches, they are wired in series with each other, and in parallel with the light. 

 

 

 

 

Here are switches that are, or can be, integrated or built into the hand controls.

Contents:

1. 36 mm hole spacing by CEV, Aprilia, Grabor
     for Domino “diamond” controls or direct mount

2. 30 mm hole spacing by CEV
     for Domino “square” controls

3. late ’80’s integrated in English, by CEV, Daelim
     for Domino “80’s black” controls

4. ’91-06 integrated with icons, by HR
    for HR controls on Tomos

5. ’01-07 integrated with icons, by Domino
     for Domino controls on Tomos

6. ’08-17 integrated with icons, by TBS
     for TBS controls on Tomos

 

Integrated controls means the electrical buttons and switches are part of the twist throttle and hand levers, rather than separate. The purpose of integrated controls is to locate the switches close to the operator’s thumbs, for increased safety and convenience, and to reduce cost and save space on the handlebar. Motorcycles had this first, because they have more buttons, generally. While the European switches below can be replaced separately from the controls, with most Taiwan and Japanese mopeds you had to buy the whole control assembly to get new switches and buttons. More on that will be in the Taiwan Mopeds parts department.

By the end of the 1970’s, the shape of pretty much everything from toasters to automobiles, that used to be rounded, was straight. Many things that were metal became plastic. On Garelli mopeds, the all curved Garelli “Oval Chrome” switch shape was modernized to CEV “Diamond Plastic”, with the same 36mm bolt spacing. The new design was much stronger and more resistant to breaking, because the sliding switch had a large platform that almost touches the base. The newer “knobs” are low and wide, not tall and thin.

3. late ’80’s plastic in English, by CEV, Daelim
     1980’s with black horn button

There were not many US-model mopeds in the late 1980’s, other than Derbi, Garelli, Jawa, Tomos, Trac (Daelim), pretty much. Except for Jawa, they all used late 1980’s black Domino controls with fully integrated switches.

At right, it’s European all-icon cousin. Over there they signal by momentarily flashing their high beam, rather than by horn. So their buttons have different functions. By 1984-85 Europe already had all-icon switches, a few years before the USA allowed them.

4. ’91-06 plastic with icons, by HR
     1990’s with blue horn button

Icons appeared first on US mopeds in 1985 on Trac/Daelim, then in 1987 on Derbi Variant Sport and DS50. In the 1980’s the world somehow realized it made more economic sense for motorcycle switches to use symbols, with one version for all, rather than using words and having to make many language versions. By the 1990’s the US had switched to icons, at the time when Tomos and Jawa were the only European mopeds remaining. There were several “remakes”: Kinetic (India) is like Vespa/Piaggio, Manet (Slovakia) is like Puch, Hero (India) is like Puch, and others. Some of those copied “80’s – 90’s Domino” controls. These HR (Hidria Rotomatika) switches below do not interchange with Domino. The HR switches are slightly smaller than Domino, and their top peg is smaller. HR switches must go on HR controls, aka “1992-2007 Tomos” controls. 

 

 

4.1 HR   Lights/engine stop switch – right side
227002        $40   Switch only, all icons

Original on 1992-2007 Tomos (A35 and A55) Sprint, Targa, ST, LX

4. 70’s – 80’s Clamp-On Switches
that say what they do, in English

Mopeds (motorized bicycles) had less strict equipment laws than motorcycles did, and still do. They don’t need to have turn signals, or a permanently-on head light. The US DOT equipment laws dictate what the switches do, what they say and where they go. Engine stop always goes on right, reachable by right thumb. Lights and horn are reachable by left thumb. After 1972 US DOT compliant switches had English words. After the mid-80’s US DOT allowed international icons.

343.cap $19  Chrome cap with horn button – see #2 below
343.clamp $4  4-piece clamp with M4x12 screw
If the knob breaks, just leave the lights always on.
On a late-77 to 86 Puch, with brown and blue/black horn wires,
if you remove this switch, and unplug the horn, the engine will not run.
The blue wire with the black stripe is an “external ignition ground” wire.
To bypass this, and make it run, ground the blue/black wire at the engine.

1 HI-LO-OFF  HORN  $19  cap used, like new, tested
2 LO-OFF-LO HORN  $19  cap used, like new, tested
3 ENGINE RUN-OFF  $14  cap used, like new
Inside the cap, the horn button spring gets weak, or the rivet gets rusty.
On most bikes, that just makes the horn weaker, but on a ’77-later Puch,
that causes the horn to stay on all of the time (so does a loose clamp).

MPclamp    $4  L or R clamp used for 342B & 343B, also fits CEV “square plastic”

These clamp-on switches are almost the integrated type, because the switch hangs over part of the control. Magura made the switch base and Merit made the switch, both in 1970’s Germany. The switch bases broke easily, and so the supply ran out early on. They were on US-model mopeds: deluxe Puch models 1978-86, and deluxe Kreidler MP-19. 

 

 

 

 

Contents: 
1. Identification
2. Parts Catalogs and Service Manuals
3. Engine Parts Comparison

 

The purpose here is to learn about Cady models, their parts differences, and then to specify or offer replacement parts. 

 

 

1. Identification

Cady Engines

Most Motobecane moped engines have the pulley-clutch on the left and the magneto-generator on the right. But Motobecane Cady and Moby X have Isodyne (same side) engines have both clutch and magneto on the left.

1.  ’66-74 19641 Isodyne M1 motor has rounded head fins,
no bulge on right case (no right bearing).

2. ’74-78 20108 Isodyne M1 motor has angled head fins,
no bulge on right case (no right bearing).

3. ’74-78 22200 Super Isodyne M3 has angled head fins,
with bulge on right case for right bearing.

4. ’75-78 22329 Super Isodyne M3 has angled head fins,
with a bearing greaser on the right case.

 

Look for the buldge

Mid-70’s Cady M1PRTS yellow and M3PRTS blue are identical.
The only visible difference is the bulge in the M3 right engine case.
Only a right side view shows this.

 

Look for the light

The headlight style and color can narrow down the identity.

3. Engine Parts Comparison

---

The purpose is to provide replacement parts for Cady, by knowing which parts are the same as on US models. Cady’s were sold in Canada, but not in the US.

 

 

 

 

 

 

 

 

Here ’66-77 Motobecane Cady engine parts are compared with other US-model Motobecane mopeds, ’57-64 Wards Riverside and ’74-80 Motobecane 50V.

 

Piston rings: In June 1976 Motobecane piston rings changed on all models. Before 6/76 the the 14821 ring gap style was GN (grano normal) where the piston ring stop pin was on one side of the ring groove. After 6/76 the 22148 ring gap style was GI (grano interno) where the piston ring pin was in the center of the ring groove. 

 

Piston: Pistons for Isodyne engines (on Cady and Moby X) are special. They have a 11 mm wrist pin, unlike most other 50cc pistons, and a total height of 47.5mm. The cylinder bore is 39mm. More precisely,, the bore ranges from 38.98 to 39.04 mm in seven tiny increments of 0.01 mm, called sorts. Cylinders and pistons are stamped with a letter. The replacement piston should be the same sort as the cylinder (unless the cylinder is worn).

After July 1976 Motobecane stopped making pistons with side-pins. From then on they made only ones with center-pins. The seven sorts of pre-6/76 replacement pistons remaining in the late 1970’s were sold until each size ran out. Then only center-pin replacements 22481-22487 were supplied when an older part number 19185-19103 was requested.  

 

 

Colors: light grey means superseded, blue means same as AV7 Vc

ULO made tail lights, reflectors, and turn signals for German mopeds, Hercules (Sachs), Kreidler, Solo, Kynast, and tail lights for many non-German mopeds, Batavus, Sparta, Puch, Peugeot, Motobecane and Honda PA50. 

ULO was founded by Moritz Ullman in 1947 in Geislingen Germany. Ullman knew how to make molded glass products, like bicycle reflectors. Today ULO is worldwide, making tail lights for cars like BMW and Audi.

250 and 248: There are two versions of 1970’s -80’s moped tail lights, 250 and 248. The black housing says the number on the inside. The 250 came first in about 1972 to 1978. The 248 replaced the 250 in about 1978 to 1984. 

Dates: ULO plastic parts have a date mark. The lens has the compliance standards and those have a start date.

Rep 250 replica, bulbs 12V 10w and 12V 5w
has no upper mount hole, loose bulb sockets
does not allow original wires under fender

The housing has no upper mount hole, so a 6mm (15/64″) hole must be drilled. The housing and lens screw hole tubes are 2mm higher and 1mm farther apart. So the lens does not directly fit an original ULO 250 housing. The bulb holder-mirror is different, a metal plate with plastic bulb sockets that are loose. The looseness might cause bulb burnout from vibration. The bulb sockets have 3mm male blade connectors, instead of 8mm male blades like the originals. So the original wires with 8mm female blade connectors will not fit. 

---

Rep 250-w replica, bulbs 6V 10w and 6V 5w
modified to accept original wires

Made from: 1) Rep-hous with the upper mount hole drilled, M5 or M6 mount bolt added, wires hole widened to 9 mm, 2) Rep-mirr with 8mm blade connectors soldered on, 3) Rep-lens, 4) Rep-ST44 screws.

Benefits: 1) allows the original wires to be reused, 2) the wire connectors are protected inside the light, unlike a plain Rep 250 where they are under the fender, 3) replaces ULO 250-2. Can also replace CEV lights without ignition ground resistors, with fender drilling.

---

Rep 250m1 replica, bulb 6V 21/5w (or 12V)
modified with ULO 1-bulb holder

Made from: 1) Rep-hous with the upper mount hole drilled, M5 or M6 mount bolt added, lens screw posts reduced in height, wires hole widened to 9 mm, 2) 250-0016 with the top cut down by 2 mm and the screw holes moved 1 mm farther apart by grinding off the outer edge, 3) Rep-lens, 4) 250-ST55 55 mm screws shortened to 50 mm.

Benefits: 1) solid bulb sockets for less bulb burn out, 2) uses the same original wires, no soldering, 3) replaces ULO 250-1. Can also replace CEV lights with ignition ground resistors, with fender drilling.

---

Rep 250m2 replica, bulbs 6V 10W and 6V 5W (or 12V)
modified with ULO 2-bulb holder

Made from: 1) Rep-hous with the upper mount hole drilled, M5 or M6 mount bolt added, the lens screw posts reduced in height, the wires hole widened to 9 mm, 2) 248-0016 with the top cut down by 2 mm and the screw holes moved 1 mm farther apart by grinding off the outer edge, 3) Rep-lens, 4) 250-ST55 55 mm screws shortened to 50 mm.

Benefits: 1) solid bulb sockets for less bulb burn out, 2) uses the same original wires, no soldering, 3) replaces ULO 250-2. Can also replace CEV lights without ignition ground resistors, with fender drilling.

The little rubber grommets #72 for the two-bulb holder-mirror, are important. When one is missing, the bulb holder is loose. Engine vibration causes the loose holder to “buzz” or vibrate and rub against the lens and housing. The buzzing causes the bulbs to burn out, and produces white powder. The white plastic dust or powder is evidence of “buzzing”.  Slices of small rubber hose can be good substitutes.

7. Saturnus Tail Lights

Saturnus tail, turn and head lights were made in Ljubljana, Slovenia. Saturnus tail lights were only on 2012-13 Tomos mopeds (US models), but they have been on European models for decades. 

 Saturnus 2-bulb tail lamp parts, from 2012 Tomos USA Parts Manual.

42  030040  50¢   2  Nut M6 self-locking (not shoulder nut like pre-2012)

The fender mount was made to interchange with CEV 9417. The upper 6mm stud on CEV 9417 was very short. That made the special shoulder nut necessary, on 1978-2012 Tomos with CEV 9417. This Saturnus mount uses separate bolts, which are longer. That eliminates the need for a more costly shoulder nut. So Saturnus mount uses a 2mm shorter nut, 2mm longer bolt, 2mm longer spacer. This makes the bolts/nuts 2mm closer to the rear tire.

8. Fiem Tail Lights

Fiem tail and turn lights are made in India. On US models, Fiem rear lamps are on early 2000’s Hero Pacer, Panther, Ankur (Hero Majestic), Cosmo Stinger (Mont) and Avanti Autopower, Mont, Supersport, Kobra (Mont) mopeds.

 

 

 

 

 

 

 

 

 

These two lights are the same. The Avanti one is missing the lower red reflector and left side reflector. The Hero one is missing the right side reflector. The top bulb is bigger for the brake light, 12V 10W with base BA15S (bayonet 12 mm single contact). The bottom bulb is smaller for the tail light, 12V 4W with base BA9S (bayonet 9 mm single contact). The tail light also illuminates the license plate through a clear bottom in the red lens.

 

The Avanti wire colors are yellow = tail, green = brake, black = ground. See wirings for more.

C2 1/4″ inline filter, round screen type, 15-1520 $6

C3 1/4″ inline filter, 90 deg paper type, 15-1796 $3

 

Screw-on Adaptors

C4: 10×1 male to 12×1 male adapter  $12 plus $2 for the seal ring

Sometimes a gas tank has a 10 x 1 threaded gas valve hole that is close to a “wall”, preventing the gas valve from screwing on or off, unless the tank is removed. Sometimes removal of the tank is very difficult, like on a Cimatti City Bike. In those cases an adaptor fitting can be used to convert to a turn-buckle type gas valve, where only the nut turns. 

A 10mm washer made of plastic, paper, or other semi-hard material provides the seal, not the threads. 

 

 

Screw-on Extenders

What is an extender and when is it needed? An extender is a piece that moves a M10-1.0 screw-on valve away from the tank.

1. For when the petcock handle hits the tank in the up (reserve) position. Most original valves had reserve pointing up, ↑reserve  off→ on↓. Original valves with an up position often had to be moved away from the bottom of the tank with an extender, to allow the handle to go straight up and not hit the tank. Some tanks had a welded-on extender, a short pipe with a 10×1 threaded hole. Some original valves had screw-on extenders. 

For this reason, most modern replacement petcocks do not have an up position. They have ←reserve  on↓ off→. That eliminates the need for an extender, a cost saving improvement.

2. For when the petcock passes through a hole in a body panel. The correct extender length lowers the petcock to the level needed to pass through a hole in a cover panel. So the petcock is hidden except for the handle, for a clean look.

3. For when something prevents installation. Sometimes part of the gas tank or frame prevents the screw-in petcock from screwing in. An example is Peugeot 102.

Turnbuckle type nuts (forward and reverse thread)

These special nuts have “forward” right-hand thread on one side and “reverse” left-hand thread on the other side. The left thread side screws onto the valve, and the right thread side screws into the tank. This allows a screw-on valve to be tightened without the valve turning, and allows the valve to face any direction 360 degrees after tightening.

C20: 22 x 1 internal right to 22 x 1 internal left  turnbuckle nut   $7 chrome

C21: 16 x 1 internal right to 16 x 1 internal left  turnbuckle nut   $2

This turnbuckle type (LH and RH) nut is used on all 16mm female (internal-thread) moped gas valves.

C21a: 14 x 1 internal right to 14 x 1 internal left  turnbuckle nut   ??

C22: 12 x 1 internal right to 12 x 1 internal left  turnbuckle nut   $1

This turnbuckle type (LH and RH) nut is used on all 12mm female (internal-thread) moped gas valves. 

 

C23: 22 x 1 internal right to 16 x 1 internal left  turnbuckle nut   N/A

This new nut was made improperly. The 16 x 1 left thread ID is to big (so it would strip off the soft alloy threads of the petcock when fully tightened) and the center-line is not straight (so the sealing surface of the petcock is at an angle to the sealing surface of the tank).

C24: 16 x 1 internal right to 12 x 1 internal left  turnbuckle nut   N/A

There are two things to watch out for with these dual diameter dual thread nuts.

1. There are two ring-shape sealing surfaces on the petcock that must be close to the same height when the nut is fully tightened. The outer 

2. The ring-shape sealing surface on the gas tank must be wide enough to press against both of the petcock sealing surfaces.

Inner Seal Discs

These rubber disks are hard and deteriorated after 30 years. The rest of the petcock is metal and lasts forever, or has round seal rings that are relatively easy to find.

Cross Referencing Hopes: The sizes, applications, and possible sourcing of these vital rubber disks is being studied. It is hoped that some of the common moped gas valves might use the same rubber seal as some kinds of Honda, Kawasaki, Suzuki, Yamaha, or others. When that information becomes available, it will be posted here. Then anyone could order a seal disk for a small brand name bike from a big brand name parts supplier. 

Flipping: Old rubber inner seal disks get hard, shrink, and become deformed. Some can be flipped over to expose a fresh unused side.

Vintage Karcoma: Left, an actual original 1970’s Karkoma (Germany) gas valve from a 1979 Kynast moped, with only 50 miles of use. 30+ years of sitting with old, rotten gasoline premix has completely clogged the passageways with hard tar, and decomposed the seal disk to where it broke when the valve was disassembled. Part of the seal disk shaped like a smile broke off and stuck to the movable plate with handle. Usually when these get sticky the handle ends up getting snapped off, in addition to the seal disk crumbling and the holes clogged.  This is the kind that uses a 3.3mm tall lip on the outer edge of the 2.0mm tall by 13.7mm diameter seal disk D4. Later 1980’s Karkoma valves did not have the lip. For those the D4 early seal disk lip must be carefully ground off. Even the last few new old stock 1970’s Karkoma seal disks, once clear orange, now cloudy gold, are brittle and crack and crumble easily in your fingers. Too bad. That is why disk D4 is N/A not available.
