I just got this early CJ motorcycle frame. It is from the 1960s.
It has the sleeved "neck" and the brackets for the frame tool box.
It also features the standard (at the time) grease fittings on the neck and the seat.
It just needs a new battery tray (easy fix). It is in very good shape for its age (over 40 years old) and does not have any damage.

This image also appears on the paper memorabilia page. It's a diagram of a CJ clutch assembly. The full size image is large and detailed and will take a few minutes to load.

Gerald found this pair of rare NOS header pipes. They're Parkerized!

Vintage sidecar taillights! Look at them all! Gerald has quite a few in inventory for use on the restorations he's doing.
And how about these vintage fender reflectors? I have one on my bike, genuine PLA-issue.
And here's a bunch of high-quality Huangshan speedometers, some of which have Chinese characters. Nice!
Interesting old CJ headlamp box with the Lu Shan brand. They were made at the Nan Chang Light Factory.

Here's one of the horns Gerald just got. It's a 6V DL79.
This is the number tag.
And here's a DL38 12V horn.
This tag is mounted on the back of a DL126A 6V horn. These number tags make the devices they are attached to all that more interesting... to some of us, anyway.

Here are two detail shots of the first type of CJ sidecar frame with side wheel suspension. They came out in 1969.
As you can see, there are grease fittings—things you don't find on the third type of CJ sidecar frame with suspension. Old parts are the best !
10/23/03  
Here are 11 of the 50 old horns Gerald just got. There are at least three different types here, both 6V and 12V.
And this is the box cover from an original Huangshan speedometer. It was manufactured by the Huang Shan Meter Factory. The enlarged image shows the entire cover.

This is a real 1960 PLA CJ750 built on an M72 frame.
These bikes had Chinese M1 engines and gearboxes.
This bike will soon undergo restoration like the Alpha Project and will then be for sale.
Some very lucky person will become the owner of this genuine and rare machine.
Here's the horn. Look at the fabric insulation on the wiring!
The buckets even has shovel brackets, typical of military bikes.
An authentic M72 frame.
Yep, that's a Huangshan speedometer.
And last but not least, the left side of the gearbox. This is indeed a veteran bike!
10/21/03  
This is an interesting M1S solo. From this perspective, it looks fairly typical.
Same here. Hey, where are the housings for the rear springs?
I wonder if that old ammo box is where the battery resides. There's a coffee can taillight, too.
Notice anything unusual here besides the curved frame? How about that radiator?!
Yep, it's a liquid cooled bike!
Is it factory? It had always been my understanding that only one prototype liquid-cooled CJ had ever been built, but perhaps that's not the case at all.
If this is a factory job, it's pretty crude.

This is a vintage Type I headlamp prior to restoration. What makes this item so cool is the CJ emblem it has stamped on it. The enlarged image shows more of the headlamp.

Gerald found the markings on this engine to be interesting.
The engine is from 1966...
...but the casing was cast in 1965.

You are looking at 26 vintage rear fenders Gerald scored at CJ Wonderland. They're all from the sixties. Most excellent!
In this view you can see that they have reflectors on them—a really great CJ item.

Gerald calls this M1S a Harley CJ.
H-D beehive taillight, Harley-style fishtails and Harley turn signals...
The OHV engine on this bike has an early type of crankcase.
The enlarged image shows the whole bike from the stern.
Running lights too!
Knobby front tire for MOTOCROSS USE ONLY!

This is a former traffic police bike, a mid-eighties M1.
Gong An Kiao Tong
It's seen better days for sure. I suppose the chances of it ever seeing service again are negligible... if even that.

Wouldn't this look sweet on a Chang? It's from an old Chinese Beijing Jeep. Aside from the amber lens, it looks very similar to the Whitney Model A taillight.
The clear lens on the bottom is for illuminating the license plate.
Here's another interesting Chinese assembly that Gerald once had mounted on his bike until the bracket broke. Look at those stars in the amber lenses.
 
A Gerald G. exclusive, a Jiang Xi Nan Chang Xiang Jiao Za Qian Chang seat tag. See Gerald's ad page if you'd like one for your bike. (I have one. They're excellent.)
Super nice finish on the hack bonnet.
And one last detail shot of the horn and port side jug. Yes!
 
Welcome to Gerald's shop, and take a gander at all those beautiful CJs!
This M1 is being built for our friend Simon Vallance in Hong Kong.
Is this a great looking horn or what?
A Guo Ying Hong Du Ji Xie Chang factory frame tag!
A better angle on the frame tag.
Just your basic M1.
Looks like a Huangshan speedometer.
Sidecar wheel & tire.
From the other side.
The back...
...and the front. Spaghetti was actually a Chinese invention.
Dynamo with a neat tag, and that fabric insulation is just another detail that makes these bikes so cool.
The dynamo again.
Old style seat pedestal with a grease zerk.
Regulator.
 
Gerald maintains a decent inventory of spare parts.
Look at the wheels and engine components.
More wheels and other chrome plated goodies.
Gaskets, seals and grommets.
Loads of chrome header pipes.
Sidecar lighting fixtures and gaskets.
Lots of handlebars and shiny bits.
 
A Chinese-made electronic regulator for a 6V bike.
Here's the side...
...and if you ever wondered what's inside, well, now you know!
 
Upper fork brackets like this one were used until the early 1970s. It's rounded in the front. It has a serial number is embossed on top.
 
What's this? A box with two brand new M1 distributors?
Let's look inside.
Here's one of them, a complete assembly.
This packing slip tells us these parts date from 1969 and were made by PLA Air Force 105 Factory. Gerald tells us these are top quality components.
 
Here we have a pair of PLA issue gas caps. As you can see, there's no chrome plating. The chain is there to prevent loss of the cap.
These caps were made at the PLA Number 7436 Factory on January 10, 1980. They were inspected by Mr. Zhao & Mr. Li according to this guarantee certificate.
 
This is a vintage driveshaft coupler from a PLA bike. It's quite a bit different from the ones on our bikes.
 
And this is a vintage PLA petcock, again, a higher quality component. The enlarged image shows the entire assembly.
 
Gerald is currently building this M1S for one of his customers. Looks like it's going to be a real beauty! There's a couple more CJs lurking in the background.
Nicely detailed M1S engine and gearbox. Look at those neat number tags! The bike started out as an M1M and is being converted into an M1S.
Spotless final drive assembly, ready to be put together and installed. This one has the high-speed gear ratio.
 
Gerald owns the tooling for the original CJ toolbox and is in the process of making new ones. These are exact duplicates of the originals and are available for US $40 plus shipping. These images show the components during manufacturing.
Back panel, interior surface.
Back panel, exterior surface.
The walls of the toolbox as seen from the bottom.
And here's the lid.
 
This is an original battery strap for a 6V M1. It conforms to the taller, old style 6V battery.
 
Is your CJ's rear fender a genuine CNAMC part? This one is, but some of the bikes exported to the States have cheesy fakes.
The way to tell is to look at the hinge. The genuine hinge is bigger and more rugged than those found on the counterfeit fenders.
 
Earlier M1 & M1M cylinder heads, especially those used on PLA bikes, had this threaded brass jacket for the sparkplug.
From the outside, it looks like this.
And a detail shot from inside. The newer heads have the threads cut directly into the aluminum. Just a little too much torque will strip them.
 
A pre-1965 sidecar running light. In the enlarged image you can see that the hole for the mounting screw is in the front instead of on the side like they are now.
Gerald scores! He just found these two GLASS sidecar running light lenses with cast CJ logos!
Here's the other one. Sweet.
 
How to tell a vintage CJ toolbox from a newer, reproduction. Here's a real one.
This is the latch receptacle.
And this is what you might call the 'male end' of the latching mechanism.
These toolboxes have pressed, one-piece covers, not welded sections.
Here you can see how the back is joined to the main body.
The components are welded together with good quality, clean beads.
 
Earlier rear flanges were designed for use with felt rear main seals like the one pictured below. Here is an example of both the older and newer types.
This is a post-1972 flange.
On the later flanges the seat is cast for the a rubber seal instead of the felt type which was actually a better seal.
The pre-1972 rear main seal was made of felt and is shown here with a rubber seal like that used on post-1972 bikes. Gerald says the felt seals never leaked.
This is a pre-1972 rear flange installed in an engine. You can see where the felt rear main seal will go.
 
This is the second type of sidecar frame that was used on CJs.
They were manufactured from 1969 until the mid-1980s.
 
This is the first type of CJ taillight. The opening on the side is for the wire. They were used on the bikes until the late seventies and are now used on the sidecar fender.
The lens is glass, not plastic. The glass was hand-painted in red except for the bottom part which was left clear for license plate illumination. Gerald has some of these taillights available for sale. His e-mail is gerald@changjiang750.com
 
This was the first type of CJ sidecar light. They were used until the early 1970s.
Here it is again from the side.
And here's the backplate and inside fixture.
 
This reflector was used on Chang Jiangs until the late 1970s.
