A. Identification
Model names: S is standard, L is deluxe, T is telescopic fork, V is variator. At first the Model 40 was made with a rigid or a telescopic fork. Then later it was only made with telescopic fork. Motobecane eliminated the unnecessary letter T, so 40TL became 40L and 40TS became 40S.
1. ’74-76 40L (US), 2. ’71-74 40L (Euro)
These have the Dimoby transmission.
1. ’76-77 50L (US), 2. ’74-76 50S (US)
These have the Dimoby transmission.
1. ’76-77 50VL (US), 2. ’71-74 50VL (Euro)
These have the Variator transmission.
Dimoby and Variator: Left is an AV7 Dc Dimoby engine (fixed pulley). Right is an AV7 Vc Variator engine (variable pulley). Both types have dual automatic centrifugal clutches, one for starting and one for running. They are the same except for the pulley-clutch system. They have the same crankcase and crankshaft.
From the right side the Dimoby and Variator engines are indistinguishable. From the left they are distinguished by the belt cover, belt cover mounts and clutch nut depth. The Variator clutch wheel sticks out about 10 mm more than Dimoby, so it has a 10 mm deeper clutch nut.

Sep 1983 MMI Price List came out after Motobecane America sold their parts inventory to Marina Mobili Inc (MMI), some time in late ’82 to early ’83. MMI computerized the parts list and added most hardware specifications. The MMI Price List and direct measurement are the sources of most hardware specifications. Direct measurement exposed many errors. Sometimes an original bike was partialy disassembled to learn the true bolt lengths and other specs.

Motor Mount Bushings (Flexiblocs)
top: #2 tube, #6 left Flexibloc, #3 right Flexibloc
bottom: #6a red rubber, #3a red rubber
The red rubbers replace just the old black rubber part. The old bushing metal shell and metal center tube are re-used. The shell is not removed from the frame so no special press tool is needed. Instead the black rubber is removed with a knife.
But the red rubber holes 9.7 and 12.4 are too small for the center tubes 11.3 and 14.0. The small hole must be widened by drilling. The large hole is a very tight fit without drilling. Drilling is recommended for both.

Cylinders on US models:
53505 is the 20mph cylinder. It says 681051 and TUM207. The top deck is higher. The exhaust port top is lower.
54328 is the 25mph cylinder. It says S25682051 and TUM207
22340 is the 30mph non-var. It says? 581051 and FB2 47
23460 is the 30mph variator. It says 682051 and most say nothing
Piston (at skirt) to cylinder clearance: new is 0.005 to 0.01 mm (0.0002 to 0.0004″), max is 0.05 mm (0.002″).
This is a very small clearance, measured at the bottom of the piston, allowed by the all-aluminum cylinder.
Usually pistons are measured at the bottom skirt, called “lower” below, because when cold, that is the widest part.
The bottom is slightly wider than the top, because there is less material, and therefore less thermal expansion.
When the piston is hot, the bottom and top are the same. The whole piston expands, as does the cylinder.
Motobecane measures just below the rings, called “upper” below. On these pistons lower is 0.02 mm bigger.
Motobecane original pistons have no marks on top, listed below as “(M)”. Inside has the M logo (some also AJ3).
< Some original replacement pistons have this logo stamped on top, listed as “(Θ)”. Inside says FRANCE.
They also have a size letter stamped on top. These were original replacements from Motobecane USA.
Other vintage aftermarket have no logo on top, listed below as “(O)”.

Note 1. The 19608 20mph case set has a ridge that only allows a 53505 20mph cylinder to fit.
Note 2. At top, the 19609 pre-80 crankshaft has less threads for the 17429 pre-80 domed square-hole flywheel nut.
Note 3. Not shown, the 19609 80-on crankshaft has more threads for the 143195 large hex flywheel nut.
Note 4. At bottom, the 19609r 80-on crankshaft is machined to take regular 6302 15 x 42 x 13 bearings instead of 6302QR 16 x 42 x 13. The press fit is precise and correct. The piston pin and needle bearing are new, included, and factory sealed in wax, that peels off.

21b110 22400 $45.0 76-81 start set, 2 of 21b,13b,7b
In June ’76 the start shoe set changed to 22400 on both Dimoby and variator clutch versions.
Dimoby clutch wheels: to 3-shoe 1, ’77 4-shoe
Variator clutch wheels: to-’76 21051, ’77-on 22925
Dimoby clutch wheels: to-’76 21683, ’77-on 22898
Variator pulley-clutches: to-’76 21056, ’77-79? 23695, ’80?-on 24659
Dimoby pulley-clutches: to-’76 21680, ’77-on 22944
The Variator clutch wheel sticks out 18mm more than the Dimoby wheel. So it’s that much closer to hitting the left pedal arm.

Note 1: The substitute o-ring is 3/32 x 3/4″ (15/16 od) which is 2.39 x 19.05 (23.83 od). But it is actually 2.65 x 19.0 (24.3 od) with an oval cross section. The o-ring groove bottom has a 21.5 mm diameter. That stretches the o-ring enough to make the OD 26.2 mm. That is slightly more than the 26.0 ID of the clutch housing where it seals at.

Note 1. There are three different sprocket sizes 11, 12 and 13 tooth. Each sprocket has a specific lock lever. The lock lever and sprocket are part of the pulley complete. So there are three pulley completes.
Note 2. The two rubber rings #4 must be removed for the replacement chain 415H because the taller link plates cause the chain to not fit the sprocket correctly. That causes grinding and skipping.

00 111 21866 $3.00 magneto terminal kit note 6
Note 1: The 21439 slide type light switch breaks easily. Because so many have been replaced, the supply has ran out. Fortunately there is an easy way to bypass the broken switch. Simply connect all three white wires together and wrap with tape. Then the lights are always on.
Note 2: In 1978 the voltage regulator under the headlight was eliminated. The horn was relocated from under the gas tank to the fork where the regulator was.
Note 3: The parts catalogs don’t show the horn mounts and they have only one horn part number 20330. So the horns and mounts are identified by actual samples and photos. 17 Motobecane horns came from stripped out bikes in the greater Los Angeles area. 8 were large with fork mount (L shape) brackets. They must be 12 volt ’78-81 because before that the regulator was in that location. 9 were small with under tank mount (twisted) brackets. They are 6 volt ’74-77. This was verified with photos from Motobecane US Models.
Note 4: 20330 horns were sold complete with mount screw, washer and a clamp-on horn button with long wire. This was an add-on option for Euro models. US models already have a built-in horn button. So here the horn is sold with the screw but without the button switch.
Note 5: Batches of used horns are tested on a running bike. They are compared and rated by loudness. Some horns get weaker with age, from corrosion on the aluminum sound plate. Any that are less loud than the others are rejected.
Note 6: Here is the Myrons wiring diagam with notes.
