Myrons Mopeds

 

Basic troubleshooting: Either the speedometer or odometer can work without the other, but the both need the cable and driver to be working. So if both speed and miles don’t work, it’s usually caused by a broken or slipping cable, and sometimes a broken or slipping driver. If either the speed or miles works, then then both the cable and driver must be good.

Stuck solid (frozen): Old speedometers become frozen where the cable enters. The grease there becomes sticky after many years. That causes the cable to break, or sometimes the driver. That is the main reason why 35 year old mopeds often have broken speedo cables. The other reason is the cable gets kinked. Speedometer drivers also become frozen after many years.

Unfreezing speedometers is done with a modified allen wrench with a tapered square end. It should fit snug in the square cable hole. Heat from a small torch is used to soften the hard tar. Once the square hole can turn a tiny bit, go backward. Go back and forth gradually more and more, adding drops of acetone or penetrating oil as necessary. Once it is free to turn by hand, but still sticky, then a drill is used to spin it faster than by hand, using a modified drill bit with a tapered square end. It can take days or weeks and dozens of repeated applications of penetrating oil and rotation on a drill, before all of the stickiness is gone. If any stickiness is left behind, it can re-freeze a year later.

Unfreezing drivers: See below for the detailed procedure that involves soaking in acetone.

Greasing drivers: Most 70’s metal speedo drivers had a grease zerk, but most 80’s plastic ones did not. One way to grease them without a grease gun or zerk is with spray chain lube. It penetrates in thin and then soon becomes thick. Another way is with a 5cc syringe and a 10-1.00 x 15 tall nut (for a Peugeot moped flywheel).

A. Speedometer Tools

A. Acetone in a drip bottle with thin spout, for dissolving tar. Acetone is a powerful solvent that dissolves ink, tar, and paint. It penetrates into soft materials like rubber and vinyl, causing them to swell, distort, and become weaker. Lacquer thinner and MEK are similar to acetone. 

B. Tri Flow drip lubricant, for applying drops of oil. It contains banana oil and microscopic Teflon spheres.

C. 1.7mm cable end bent. This is for counting revolutions when measuring gear ratio on 1.8-hole drivers.

D. 1.9mm cable end straight. This is for spinning 2.0-hole speedos on a drill.

E. Modified allen wrench, ground to a 1.9mm square on the small end. This is for applying torque to a stuck 2.0-hole speedo, and for rotating back and forth once it is able to move, or around and around if it’s able to move in circles.

F. Tapered square end shaft, for spinning 2.7-hole speedos with a drill.

G. Modified allen wrench, ground to a 2.6mm square on the small end. This is for applying torque to a stuck 2.7-hole speedo, and for rotating back and forth once it is able to move, or around and around if it’s able to move in circles.

H. Small screwdriver for rotating 2.7-hole speedos.

I. Greaser made from a 5 cc syringe and a M10-1.0 x 15 hex15 tall-thin nut (for a Peugeot flywheel). It was pure luck that the nut threaded tightly onto the smooth, tapered plastic spout. Of course, this is only for M10-1.0 thread speedo drivers, which fortunately is the majority.

B. Unfreezing Huret speedo drivers

1970’s Huret speedometers and drivers become frozen (stuck solid) after 40 years. Other kinds do also but not as much. Even new speedos and driver become frozen, because the Huret grease decomposes into hard sticky tar. Out of a sample of 30 new and 10 used 70’s Huret speedo drivers, all were frozen solid.  

Ten frozen Huret speedo drivers were soaked in acetone in this sealed glass jar. After 17 hours they were removed and tested. 8 out of 10 were able to move, but 2 were still stuck solid. Those 2 were re-soaked with a new batch of frozen ones.

Acetone breaks down hard insoluble tar that is like taffy, and makes it less sticky and more soluble in diesel fuel or gasoline. When first removed from a day of soaking in acetone, the tar would ooze out like warm peanut butter when compressed air was applied to the cable hole. But after 20 minutes, that same peanut butter re-solidified, as the acetone evaporated out of it. So they need to go into the diesel fuel bath right after the acetone bath, rather than drying out first. They also need rotation to spread the solvent to all areas, like stirring.

The 8 unfroze drivers were then soaked in diesel fuel along with 7 others that did not need an acetone bath. The diesel fuel dissolves the loosened tar visible on the outside, as well as some soluble tar on the inside. After 2 days of soaking, 11 out of 15 moved freely, but 4 were still sticky. Those 4 were returned to the acetone bath pickle jar. The rest were brushed, cleaned and then blow dried with compressed air. 

While waiting to be greased, 1 of the 11 drivers refroze and 2 became sticky, as acetone evaporated from the grease inside. Those 3 were returned to the pickle jar of acetone.

The remaining 8 clean and free drivers were greased with a modified syringe, made from a 5 cc syringe and a 10-1.00 x 15 tall nut (for a Peugeot moped flywheel). Each driver took 0.2 to 0.6 cc of lithium grease. The syringe has to be squeezed really hard with both hands. The grease goes in slowly. The gears are rotated in between squeezes to spread out the grease. Soon the old black grease and solvent oozes out from the thin gaps, like on the left driver in the above photo. The feel goes from gritty to greasy as the new grease pushes out solvent and grit.  

The last step was straitening the fingers as needed, with a needle-nose pliers.

17 stuck drivers became 8 ready to use drivers. For the other 9 the entire process was repeated, as many times as necessary. This is how new and used 1970’s Huret (and others) speedo drivers are refurbished in preparation for sale.

A. Huret Speedometers

 

 

 

Long term testing: These were unfroze with acetone and re-lubricated with Tri-Flow. Then they sat on a parts shelf for four years in zip-lock bags. After that long, none had become stuck/frozen.

Huret-2.7 Motobecane speedometers: The cover is glass, so it resists scratching. Repeated exposure to sunlight fades the white background to yellow and the blue numbers to white. When the numbers are faded out the needle is still red, so speed can be estimated, like telling time on a clock with no numbers.

# price  miles   all are working normally unless noted 
1  N/A  1780  excellent condition, works good
2  $55  5261  dark numbers, works good, but returns to 5mph not 0
3  $45  2024  barely visible numbers, works good
4  $40  7365  invisible numbers, works good
5  $35  5337  completely invisible numbers, works good

 

 

Motobecane speedo service: Accessing the needle requires removing the lower plate that hides the needle. That is done by applying pressure to the two white posts that stick through the face plate.

Speed Testing: A hand drill was set to spin at a constant speed (by a stop screw in the trigger). Each speedo was spun for 30-50 seconds. The final speed was recorded.

Huret-2.7 60mm round speedometers: The test speeds all agreed quite well. These have great dampening, no jumping unless noted. The clear cover is glass, not plastic. So it does not get dull or scratched.

Preparation: All of these Huret drivers were initially frozen, tarry on the inside. Some were also tarry on the outside. Scroll down for the detailed procedure for unfreezing, cleaning and lubing. All of those listed for sale have been serviced and are ready for use.

Reversible: Most of these Huret speedo drivers are reversible. They can be used on either side of the bike, because the cable can attach to either end, resulting in opposite rotation. Most are on the left side. All have to rotate the cable clockwise, viewed from above the speedometer.

Markings: The brass end caps on VDO speedo drivers are marked with the tire or rim that they are geared for. 1970’s metal drivers are marked with the tire outer diameter (23, 22, 21, 20). 1980’s plastic drivers are marked with the rim size (19, 18, 17, 16). The tire OD’s are 4 inches more than the rim sizes, because moped tires are about 2 inches tall.

Batch marking: The marking that looks like a gear ratio is not. It’s some kind of batch number.

Tire marking: On some (21LH 6/61 and 23LH 23/5) the tire size marking disagrees with the measured gear ratio. 

Side: Most (10 of 14) VDO speedo drivers are for the left side. Some (2 of 14) are for right side. Some (2 of 14) are for left or right side. On those the cable can attach in two places with opposite rotation. 

Greasing: The 70’s metal VDO speedo drivers had a grease zerk, but the 80’s plastic ones did not. One way to grease them without a grease gun or zerk is with spray chain lube. It penetrates in thin and then soon becomes thick. Another way is with a 5cc syringe and a 10-1.00 x 15 tall nut (for a Peugeot moped flywheel).

Derbi 1.8/1.8 cables: Many Derbi speedometer cables have a kink below the speedometer that causes the inner wire to break repeatedly. The kink is from the back of the “pancake” headlight pushing the speedo cable back. There is no easy remedy. As with any speedometer cable, any kink or sudden change in direction will eventually cause the inner cable wire to break there, because as it rotates it is being bent back and forth.

750 29.5  Rep2/750 Wrong upper thread, see note 2

Note 1: RepT is made from Rep1 in 4 steps. 1. Using a tapered punch, vice and hammer, the upper end tube is bent wider at the entrance flare, from 7.2 to 7.5 mm ID, to fit the 7.4 OD lip on the CEV speedometer. 2. A C-clip, made from a section of a paper clip, is added inside the upper plastic screw cap, if it does not screw on far enough to retain the upper end tube solid, straight and centered. 3. The inner wire is inverted. 4. The 2.0+ mm weld bulge at the tip of the upper square end is ground off to make the tip a 1.9 mm square.

Note 2: Rep2 cannot screw onto a CEV speedometer because the upper end cap thread is incorrect. It is M11-1.0 instead of M11-0.75. So the conduit, with the incorrect end cap trapped on it, is useless. But the inner wire has a good use. It can replace a broken inner wire on an Tomos 227.698 cable, original on 1992 to 2002. Some might need grinding of the 1.8+ mm weld bulge on the lower end to make the tip a 1.7 mm square.

Speedometers on vintage mopeds are all mechanical type, not electronic. A driver or sender on the front wheel rotates the cable. The cable, with a spinning wire inside, goes up to the speedometer head. Inside the gauge a spinning magnet moves the needle. An odometer or mileage meter is also driven by the cable, with gears.  

Speedo families are heads, cables and drivers that have certain things in common. The head and driver threads are the same. The head and driver square cable holes are the same. So heads, cables and drivers within the same family all interchange. 

Square cable holes are a little bigger than square cable ends. A 2.0mm hole takes a 1.85 to 1.95mm cable, and a 2.75mm hole takes a 2.55 to 2.70mm cable. This is a source of confusion. 

Speedo drivers: On the front wheel is small gear box that changes the wheel rotation into the cable rotation. 

Speedo driver Side means what side of the front wheel would make the driver rotate the cable clockwise, viewed from above. Reversing the side by flipping the front wheel reverses the speedo cable rotation.

Speedo driver Type: Most drivers have the cable exiting below the axle. Most left side drivers are type d because they look like a letter “d”. Most right side ones are type b because they resemble letter “b”. But some type d’s are for right side, and some type b’s are for left. This is because the worm gear teeth can be wound left or right, like a left or right hand thread bolt.

Speedo driver Ratio means how many times the cable rotates for each wheel rotation. Larger diameter tires require higher driver ratios to achieve the same cable rotation. Smaller tires require lower ratios. The gear ratio is related to the angle of the gear teeth as well as the tooth counts.

Speedo cables can be different lengths for the same bike. Aiming the speedo driver more upward requires a shorter cable. Aiming the driver more downward requires a longer cable. When the front suspension goes over bumps, the speedo cable has to flex up and down. Aiming the driver 90 degrees to the suspension travel makes the least stress on the cable and the least interference with the suspension movement. Most newer bikes are that way. But then the cable hangs out a lot, and requires a fender eyelet to help prevent the long cable from getting snagged on things when parking or maneuvering.

A. CEV Speedometers

 CEV 2.0/2.0 60mm speedometers in Nov 2024

Speed testing: They are all tested on the same drill, for comparison of speed accuracy. The odometer accuracy never varies – it either works or not. It takes up to 3 minutes at 20mph to click off one mile. Each speedometer is tested for at least 3 minutes, some over 10 minutes all together. Once all of the 17 tested speeds are retested and verified, an average speed can be calculated. First the highest and lowest are ignored. Then the remaining 15 test speeds are added up and the sum is divided by 15 to give 23.8 average. You can see that most of the speedos tested at 23, 24, or 25 mph. The accuracy is an important factor in determining the price. The condition of the glass, face, and needle are also important. 

CEV-2.0/2.0 60mm round speedometers: 15 out of 17 were originally frozen. They have all been cleaned, checked, and lubed, and tested.

B. CEV Speedo Drivers

CEV speedo drivers come in a wide range of styles, sizes, and ratios, perhaps 100 kinds. Here are only about half of them, the ones with small axle holes, mostly 11 or 12 mm, for lightweight motorcycles, mini-cycles and mopeds.

CEV speedo driver part numbers in the 1960’s and 70’s all had a 4-digit number starting with 7. They were sequential, here starting at 7121. Most older ones (lower part numbers) had higher ratios for larger tires 18 and 19 inch. But only the last 3 digits were stamped on the driver, at the brass end cap. After the mid 1980’s the 3-digit stamped-on numbers replaced 4-digit numbers. So a CEV 7416 is the same as a CEV 416. But some changed, like the CEV 7408 with an 11 mm axle hole became the CEV 408 with a 12 mm axle hole.

Grease zerk or cap: CEV drivers in the 1960’s, 70’s and early 80’s all had grease zerks for applying grease with a grease gun, up to number 7429. The 1982 Marina Mobili Parts Catalog and 1985 price list contain 9 CEV drivers from 7121 to 7429 for mopeds, mini-cycles and lightweight motorcycles. Some time after that, in the late 1980’s or 90’s, starting with number 7430, the zerk was discontinued, replaced at first by a small non-removable cap, and then a large removable grease cap. With that you just push the grease in with your finger tip. That was the most visible thing that changed. Some versions also got thinner. Here we use the older 4-digit numbers for the older grease zerk versions, and the newer 3-digit numbers for the newer grease cap versions. 

Right or left: The cable must rotate clockwise, looking down from the speedometer. So for each side of the bike there are right or left types. It happens that CEV worm gear drives are all wound in the same direction, like a normal bolt. There are no reverse threads inside. So the shape of the speedo driver determines what side of the bike it goes on. Ones that resemble a “d” go on the left, and “b” ones go on right. This is true for CEV speedo drivers, but not all other makes.

Tomos speedo drivers: In mid-2008 Tomos in Slovenia began outsourcing most production to India. Components also changed to India-made, such as the speedo driver. The part number did not change, but the square cable hole grew from 1.8 to 2.0 mm. This caused the square cable to slip often. The simple no-cost remedy is to smash the square 1.7 x 1.7 end of the cable into a rectangle 1.9 x 1.5. 

Gear ratios: Several known tire sizes and gear ratios were used to calculate all others. First the tire outer diameter (OD) for a 1.6 ratio was guessed. Then all the other tire OD’s were calculated from that. The guess was revised, tire OD’s recalculated and compared. This was repeated, to finally match the known values.

Tire size: These vintage tires all have a 100% profile. The height is 100% of the width. So a 2.25-17 tire has an outer diameter of 17 + 2.25 + 2.25 = 21.5 inch. A 2.75-16 also has that same OD. Different tire sizes can have the same outer diameter.

A C-clip, made from a section of a paper clip, is added inside the upper plastic screw cap, if it does not screw on far enough to retain the upper end tube solid, straight and centered. 3. The 2.0+ mm weld bulge at the tip of the lower square end is ground off to make the tip a 1.9 mm square. 4. The 1.7 mm upper square end is formed into a slight rectangle by gentle hammer taps.

Information

Welcome. The magneto has two separate functions, 1) produce sparks for ignition, 2) produce electric power for lights.

1) Ignition Pulses: The magneto produces precisely timed pulses, which are transformed into sparks by an internal or external coil.

2) Lights Power: The lights power is normally 6 volts alternating current (6V AC). Normally the correct bulbs are used, and none are burned out. But under certain circumstances the voltage can be less, like 3 volts, or more, like 10 volts. When two or more bulbs share the same generator wire, and one of the bulbs burns out, the others will get an over-voltage, like 8 or 10 volts, become instantly bright and soon burn out. The total watts of the bulbs has to match the watts of the generator, for the voltage to be 6 volts. If the bulb watts is more, then the voltage is less so the light is dim. Bosch makes magnetos with extra generator coils, one for each light, to eliminate the over-voltage and under-voltage problem.

Magneto-Generator History: Moped magnetos changed as moped lights changed over the years. In the 1960’s not many countries worldwide had laws about the brightness of moped lights or the placement of switches and buttons. Mopeds did not have brake lights or extra generator coils for them. A typical 1960’s moped had a 15 watt headlight and a 2 watt tail light, both powered by the same 17 watt generator coil.

Starting in 1972, the USA adopted safety standards for motorcycles and motor-driven cycles (Mopeds had not been defined yet). Lights, rims, brakes and tires had to be US DOT approved. Tail lights had to shine to the sides. Engine stop switches/buttons had to be reachable by the right thumb, while horn and light switches had to be reachable by the left thumb. Switches and fuel petcocks had to be labeled and say what they do. Brake lights were required.

Then in historic 1976 the USA adopted safety standards specifically for mopeds and motorized bicycles. The brake light had to be brighter (at least 10 watts) and not cause the headlight to get dimmer.

Internal and External Ignition Ground: To supply the required independent brake light power, there were two solutions. 1) Internal Ignition Ground, where the ignition source coil internal ground was kept the same, and an extra generator coil was added or 2) External Ignition Ground, where the ignition source coil internal ground was relocated to outside of the engine and used as a brake light power source. Bosch made both magneto types, in both sizes 80 and 90 mm.

Swapping Flywheels: Nearly identical flywheels can have different timing angles. That means the woodruff key groove is at a different angles to the “bump” on the points cam. So you can swap flywheels but your ignition timing would be way off.   more to follow…

 

It don’t come easy. Parts catalogs list the bike maker part numbers, but most do not also give the component maker part number.

 

 

 

 

 

Bosch coil part numbers come from the packaging of new coils. Sometimes empty ripped-up original boxes are pieced back together, to get the part number translation, such as Sachs-to-Bosch. 1970’s-80’s armatures also have the last 3 digits stamped on.

Bosch stator part numbers are on the back of the base plate. The first 7 digits are cast in, the same for all. The last 3 digits of the stator assembly part number are stamped on by the factory when the coils are attached.

Bosch stator identification: Each engine has a different and unique rubber grommet for the wires to pass through. A pile of used moped stators can be sorted by grommet type, which is engine type. The ones missing grommets can be matched to the grommet ones by stator part number. This is done without any books or manuals. Specifications, illustrations, or part numbers from books, manuals, internet photos are additional forms of ID. All forms of ID must agree.

Sachs 504 stators are 4-wire, 3-coil. Top rear coils is ignition (blue wire). Top front is brake light (green wire and green/black wire). Bottom coil is lights (yellow wire). The ignition and light coils are grounded internally. The brake light coil has an external ground. Because of the internal ground on the ignition source coil, the points continuity cannot be checked unless the source coil is disconnected. Bosch has provided a condenser with a screw-on nut with detachable eyelet connector wires, for testing the points for continuity. Otherwise, the ohms of the coil is almost the same as the ohms of the points. See Service/Electrical/Wiring Diagrams/Sparta Foxi for more Sparta wiring info.

This Bosch 2207 031 161 Kreidler stator assembly is the same as a Bosch 2207 031 160 Sachs 504 stator, except for the 1-wire brake light coil. But the flywheel is very different.

Use a 2-wire brake light coil for a Sachs 504, as a substitute for a 1-wire Kreidler type. The additional green/black wire must be grounded to the frame. Because there were 10 times more Sachs 504’s sold in late 1970’s California than Kreidlers, the coils for Sachs are not as scarce.

16  1  008.19.?? 1214 210 462 generator armature 10W 2-wire

This 009 flywheel is the same as the more common 002. The lighting coils are different. The lights coil has more windings, and the brake light coil has two wires, green and green/black, instead of just one green wire. This provided power for recharging the turn signal battery without dimming the other lights. Read more in Wirings Gallery, scroll down to “K” Kreidler.

This 2-wire 10W generator armature 1214 210 462 is physically the same as a 2-wire one 1214 210 450, and can be a substitute. When changing from 1 to 2 wires, the additional green/black wire must be grounded to the frame.

Condenser: 1950’s-60’s had solder type condensers and no-wire points. The points-to-condenser wire was sold separately. 1970’s-80’s had screw post type condensers and with-wire points. No more soldering. A solder-type condenser can be replaced with a screw post type by adding eyelet connectors to the three wire ends. The three wires that go to the condenser are from the points, from the source coil, and from the spark coil.

0212 010 001 flywheels: Several individually numbered Bosch magneto flywheels for Sachs 504 engines are offered for sale below. The focus is on the condition of the surface of the points cam. All of the flywheels are otherwise straight and with a good woodruff key groove. The flywheel rotates counter clockwise, viewed from it’s outer facing side. Two views, 180 degrees apart, of each flywheel are shown below. The “A” side is the upwards ramp that opens the points. This is where the most wear occurs, and where the most smoothness and precision are needed, or else the points rubbing block wears down prematurely. The “B” side shows most of the key groove. Any rust has not been cleaned off yet, but is not a problem, other than rust on the outside surface of the points cam.

Flywheels 1, 3, 4, 6, 7, 8, 9 have been sold.

Flywheel 2: The cam has been cleaned. Never mind the orange rust. The cam surface is all good on the outboard side of the points rubbing block lane. But it has some pitting near the top of the up ramp on the inboard side of the lane.

Flywheel 5: It has not been cleaned yet. Looks like it would clean up good, with steel wool, then emery cloth(s) and polishing. Side A shows pits in the middle of the plateau. So the whole cam has to be sanded down evenly, then polished smooth.

Flywheel 10: Not shown, new and fresh.

2207 031 160 stators available are #1,2,3 and 5.

These all have no connectors on the wire ends. They attach to a screw-terminal strip, instead of plugging in.
These have good wires. But some cost $10-$20 less, because the wires are cut or damaged.
Points are not worn out. They are cleaned, prepared and tested. Condenser is good, as are coils and wires.

1. Ducati Magnetos on Tomos

Tomos mopeds have been equipped with Ducati, ZEM, CEV, Iskra, AET and other magnetos. They are all included in IDM-Iskra-AET Magnetos. ZEM is a remake or a rename of Ducati (DEM Ducati Elettrotecnica Microfarad).

Ducati or ZEM 31.17.11 magneto-generator is a 2-wire internal ignition ground type for countries that do not require a brake light.

Ducati or ZEM 31.17.30 magneto-generator is a 3-wire external ignition ground type for countries like the US that require a brake light. Like many other US-model moped magnetos, the brake light is powered by the ignition source coil ground. This was to meet the US DOT requirement that the headlight not get dim when the brake light was on. The two-coil generator has three outputs, the black ignition wire from the points to the spark coil, the blue ignition ground wire that is grounded through the brake light or brake light switches, and the yellow light wire the provides 6V AC 30 watts for light and horn.

Tomos US models in 1974 to 1985 had this type of magneto, with the brake light switches wired in series and normally closed when installed. If you removed the tail light and squeeze either brake, the engine would die. Starting in 1986 Tomos improved the electrical system with a solid-state-regulated single lighting yellow wire, a ignition black wire, and an internal ignition ground. So the engine never dies, on a 1986 and later Tomos with the 2-wire Iskra magneto, when the tail light wires are unplugged and the brake is applied. When the magneto type changed from 1985 to 86, the wiring also changed.

These Ducati and ZEM complete magnetos, with 94mm ID flywheel and 90mm 3-bolt stator, will interchange with 90mm ID flywheel and 90mm 3-bolt stator Bosch complete magnetos and other Bosch compatibles like Iskra, except for the width and position of the key groove that determines the ignition timing.

These are counterclockwise ⇐left rotation. Points are M14 CEV type “right hand” (the brown part looks like your right hand sideways with fingers bent). The Ducati base plate has a 17.9mm condenser hole instead of 18.0. So the condenser is MMI# M17T which is the same as a modern M17.  Source coils have M4 x 20 screws with 57 mm spacing.

2. Ducati Magnetos on Minarelli

Ducati magnetos were on many 1950’s to 1980’s Minarelli engines, along with CEV and Bosch. 

Oldest ones had an internal spark coil, where the spark plug wire comes out of the engine. Newest ones had an external spark coil with a spark plug wire coming out of it. In between oldest and newest was both types.

Wires: In the list below the wires column has symbols. ♦ is a black magneto wire for lights, ♦ is a red magneto wire for ignition, o is a thick magneto wire for an internal spark coil, blank is no thick magneto wire for an external spark coil.

Some bike models with brake lights or batteries have a third magneto wire ♦ purple. The third wire can be from the ignition source coil (external ignition ground), or from the lighting coil as an additional output (internal ignition ground). 

This is a Ducati 31.12.38 magneto from a 1974 Indian ME76, Minarelli P6-70 engine, USA street model with a brake light. It has 3 output wires. Red wire is ignition (points to spark coil). Black wire is power for lights. Purple wire is power for the brake light (or battery charging if there is a battery).

  1. Tomos Magnetos 
  2. Service Info

 

  IDM magnetos, made in Italy, are on some early-to-mid-1990’s Tomos. They are CEV-compatible, and have the same appearance.

Iskra magnetos are made in Slovenia (which was part of Yugoslavia before 1991). They are original equipment on most Tomos mopeds from 1989 to 2007. Iskra means “spark” in Slovenian.

  AET  After about 1993 Iskra magnetos were labeled AET. Iskra electric motors, AET electric equipment and Tomos mopeds were (or are) divisions of Hidria, a family of Slovenian manufacturing companies. Iskra-AET magnetos have the AET logo stamped on the flywheel, and the Iskra name cast into the back side of the stator base plate. So they can be called by either name.

Tomos mopeds, USA models, had many magnetos, but many were interchangeable. The magneto brands Ducati, ZEM, CEV, IDM, and Iskra-AET, each had different versions. They are all listed below, in order of VIN code and year range.

In 1998 the 230.327 magneto changed to a “4-star” or “plus sign” design. 3 of the 4 coils were for lighting, connected in series, and one coil was for ignition. So the output wires did not change. The base plate screws changed, from three 4 mm, to two 5 mm.
1974-1997 engine cases had only mounts for 3-M4-screw stator plates.
1998-later engine cases had mounts for both 2-M5 and 3-M4-screw base plates.

In 2003 the engine case, on all models, became electric-start-ready. The magneto did not change, but the magneto part number did because a rubber grommet was added.

In 2001-02 the A35 Revival was the first Tomos with electric start. The 230.842 magneto was the same as a 230.327, except it had an extra wire for battery charging, and a large flat gear on top, for electric starting.

On A55 Engines 2004 to 2017

In 2004-05 the A55 engine came out. It was cleaner and more efficient, to meet new 2006 EPA pollution standards. The A55 had a different magneto with an external pulser, which added two more wires.

From 2004 to 2009, the A55 engine had AET 11.170.017 for electric start models, and AET 11.170.027 for non-electric start models. From 2010 to 2013 all models had electric-start type magnetos, with a ring gear and extra wire. But they were made by Kinetic and said 12V 60W.

Engine cases: You don’t have to know the year or model to know what magneto(s) fit at particular Tomos. You only have to know what left-side engine case it has. The stator plate has to fit the engine case, and the flywheel has to fit the crank.

 

From 1974 to 1997 there were three M4-0.7 thread stator plate holes, for A3 and early A35. 3 total.

From 1998 to 2002 two M5-0.8 thread stator plate holes were added, for mid A35. 5 total, 3 unused.

From 2003 to 2006 the electric start affected the wires grommet, for late A35. 7 holes total, 5 unused

From 2003 to 2013 two M6-1.0 thread pulser coil holes were added, for A55. 7 holes total, 3 unused.

 

Flywheels: All the flywheels, both 80 and 90 mm ID, fit the same crank, but they can have different points cams or ignition triggers. Some flywheels do interchange, some might, and some don’t.
