Jawa 207 piston
Jawa Pistons: Jawa 39mm cylinders, pistons and rings are slightly bigger than others. A Motobecane mid-size “E” cylinder is 38.99, while a Jawa “B” cylinder is 39.02 mm. Jawa pistons have “rounded M” and “circled S” logos stamped on top, the size code “B Y” (or “1B Y” or “2B Y” etc), and the arrow that points toward the exhaust side. Jawa pistons are classified in the manuals as A, B, or C by tiny (100 microns) size differences. The actual replacements are all “B”. To see the pistons for sale, with prices and more info, click the link in the price column to go to the Pistons section. Scroll down to Pistons with 14mm Pins, at the bottom of the list. To see the rings for sale, click the price link to go to the Rings section. Scroll down to 39mm rings, for standard rings, specifically “39.02 x 2.00 GI”.

Jawa Chain: The Jawa motor chain is not a standard 415 moped chain, although it has the same pitch and width. It has thicker pins, 4.4 instead of 4.1mm. More importantly, it has bigger rollers, 8.4 instead of 7.7mm. Because the Jawa sprockets are made for bigger rollers, they look similar to worn out standard sprockets. The valleys between the teeth are wider and deeper, making the tops of the teeth more pointed. So a 415H moped chain will work OK, but not great, on unworn Jawa sprockets. But if the Jawa sprockets are worn, the chain might skip and jump off.

Jawa brake shoes
L, 2.5 lining for Ø85 drums
(on Jawa spoke wheels)
R, 5.0 lining for Ø90 drums
(on aluminum wheels)
Jawa Spokes: Jawa spokes for 16″ rims are all 160mm long (198mm for 19″ rims). There are two kinds, inner and outer. The outer ones go through the hub holes from inside to outside, and have a longer and sharper bent section. The inner ones go through the hub holes from outside to inside, and have a shorter bent section. Each wheel has 18 inner and 18 outer spokes, alternating, for a total of 36. It was an educated guess which part number was for which type. Inners were 07-4016 and outers were 07-4022, at least in this list. Nowhere else is this difference noted. It does not matter much, since either type of spoke will work, with some minor bending during tensioning/truing.
Jawa Freewheel
Jawa Brakes: Jawa brake shoes are not like any other western European or Asian brake shoe. Most are for a 85mm drum diameter. Some Jawa mopeds with aluminum “mag” wheels have 90mm drums. For those Jawa made the same brake shoes, but with thicker lining, 5mm instead of 2.5.
Jawa LH 18T Freewheels made by Velo, say what year they were made, here 1976, 77, 78.
Jawa Freewheel: The “free wheeling hub” with sprocket, for the pedal chain is on the left side of the bike. All other US mopeds, except Benelli, and virtually every bicycle, with a freewheel, has a pedal chain on the right side. A right side freewheel screws onto a hub and tightens clockwise, as the bike is pedaled. So the hub has a standard right hand thread. But a left side freewheel needs an opposite thread, so it tightens counter-clockwise, as the bike is pedaled. Jawa specifies the freewheel thread in the Model 28 Parts List. It is M35 x 1.0 L.H. (left hand). So Jawa freewheels and rear hubs are special.
Notice how the back side of a Jawa freewheel, lower right, looks like the front side of a conventional freewheel, top left, except for no removal slots. For many years Shaun mistakenly thought Jawa freewheels were conventional right hand thread ones that were missing the removal tool slots. It is not easy to tell the direction of such a fine thread. Tragically some of those special left hand freewheels got thrown away in the 1990’s along with a few Taiwan bicycle ones that were truly missing the removal slots.
Just a reminder, freewheels tighten by pedalling. No tool is needed to install one. But removal requires a special tool, which comes in different styles and sizes. If the bicycle or moped is pedaled hard, then the freewheel will become very tight and difficult to remove.

Each cable was made in long or short versions. Long is for tall hi-rise handlebars like on the 207.311.
US models 1976-81 had Jawa controls. Those had inline brake light switches on the brake cables.
US models 1982-83 had Domino controls. Those had brake light switches on the controls, not the cables.
The 1982-83 top tank had low bars, short cables. The 1981-83 step thru had high bars, long cables.

Jawa Magneto Coils
Jawa 207 magnetos have four source coils (and one pulse coil). Two of them are combined in series to make one. So there are three independent generator outputs, ignition (coil 4b), lighting (coil 7a plus 7b), and horn or brake light (coil 6). The ignition never has anything to do with the lights. The brake light does not make the head light dim at all. So it is like three separate little generators, all in one place. More about Jawa electrical can be found in the Wiring Diagrams gallery. Scroll down to “J” Jawa.

Jawa Service Bulletin Aug 1981
Jawa Ignition Upgrade Kit
In 1981 Jawa moped dealers across the US were sent this Service Bulletin #1. It says how to update pre-1978 (model 207.011) ignitions by replacing the old red Tranzimo unit, and the old stator ring with pulse coil, with the newer system, shown at right. The new system had been in use for two years on the 207.111 models, and was proven to be more reliable. Too bad MM does not have any more of those ignition upgrade kits.
