High Performance Parts
Carburettors |
High performace carburettors.
For better response and higher speed you can install the high performance carburetors. These carburetors offer higher top speed, faster response, better mileage, do not vacuum lock, and stay in tune. We also have constant velocity carburetors and electronic constant velocity carburetors. |

high performace carburettor |
Installing new caburettors is very basic. Adjusting new carburettors however, is rocket science. We highly recommend that you leave this to us. Rememeber that your engine over time has asdjusted itself to the carburettors that you have been
using. When you change the carbs the engine tends to get a bit 'confused' more gas, more air, better flow. If you don't adjust everything properly it can result in uneven running and misfire. |

High Performance Parts
Monster pistons |
|
3 and 4 ring high performace pistons.
For better response and higher speed you can install the high performance pistons. These pistons offer higher top speed, faster response, better mileage. |
|
Installing 3 and 4 ring high compression pistons is The number one tune up for the Chang Jiang engine. It will increase your engines performance with up to 30% and it will seriously reduce emission fumes. |
|
We have high compression pistons for both 24 HP Flathead and 32 HP OVH Chang Jiang engines in stock. |
 |
if you only want the best for your Chang Jiang 750, you can install 4 ring super pistons. These are the top of the pop.
Spot the difference.. 3 and 4 ring high compression piston. Notice the extra ring and the concave buttom. |
|
|
Installing pistons is a fairly delicate matter. We recommend that you let us do it. It doesn't take too long. Again, call in advance and we can have it done while you wait. |

Engines
New CJ 750 F Over Head Valve 12 volt engine |
|
The basic 32 HP OVH engine
| |
|
|
Offers increased accelaration ans speed. Heats less. If you do a lot of long distance and mountain riding, this is the engine you want in your bike. |
|
|
|
|
|
|
|
|
 |
High speed rear differential gear
The high speed rear differential (rear drive gear) is one of the very popular tune-up that we do a lot of. It is especially popular with riders that go on longer trips.
With the improved rear diff. you gain about 12-15 km/h top speed and you get a much smoother ride. |
|
Super quality High speed rear differential. This is a standard tune up for both 24 HP Flathead and 32 HP OHV. The High speed rear differential is one of the many tune-ups included in our Premium Bike restorations. |
|
| |
 |
The diiferential is fairly easy to mount. So if you are a gear head and you have the necessary tools, bike mounts, workspace and time, you can put it on yourself. If not, we will be happy to do it for you. It's not very expensive, and if you come at the right time or call in advance we can usually have it on your bike while you wait. |

Extra Deep Oil Sumps
High quality cast aluminium deep oil sump with extra large cooling fins. Cast in one piece, no weldings. |
|
| |
 |
The extra deep cast aluminium oil sump holds more oil thus increasing oil temperature stability. Prevents overheating, gives smoother running and fewer oil checks. Notice the extra large cooling fins, this keeps the oil temprature low and stable. This is another must have tune up for long distance riding. |
|
|
Some riders choose to install a high capacity oil pump on their bikes, if this is done, you HAVE to get a deep oil sump. If not, your bike will surely overheat very fast. Mounting a new oil sump is not the most difficult task. However it does tend to get very messy. So if you don't have the proper facillities to perform this operation at home, we suggest that you let us mount it for you. If you call in advance we can do it while you wait. If you decide to do it yourself, remember to dispose of the old oil properly, please don't just tuck it into the sewer, Beijings sewage system has enough problems already. Put it in an old plastic container and hand it over to one of your local garbage collectors. |

High speed 4th gear
Super quality high speed 4th gear drive. |
|
These babys will increases the top speed of your bike with about 5-10 km/h. Another must tune up for those long trips. Apart from increased march speed you also gain better milage, smoother riding at high speeds and reduced engine heat.
| |
Super sturdy High speed 4th gear with a ratio of 1.19:1 as opposed to the standard 1.3:1 you can really feel the difference when you are doing high speeds. This is a standard tune up for both 24 HP Flathead and 32 HP OHV. The High speed 4th gear is another one of the many tune-ups included in our Premium Bike restoration package. |

Thin air filters
The thin air filters are becoming increasingly popular among Chang Jiang 750 riders. |
|
 |
They offer better air in take, which in turn gives your engine better combustion. Better combustion equals smoother running, higher speeds, better accelaration and better milage. Moreover they are easier to clean and change. Oh, yeah and they also look incredibley cool.
These slick high quality air filters are also a standard option included on our Premium restoration bikes and they work equally well on the 24 HP Flathead and the Super OVH engine.
We also do specialized filters and our custom built airfilters are becoming very popular. |
The thinest of the air filters come in two standard types. The high-performance air filter also comes in a modified semi-thin type, where the standard closed top lid has been |
|
replaced by a thinner open lid. Actually it's just the top of the lid that has been cut off to allow a larger air in take. See below.

Disc Brakes
There is no way getting around the fact that the Chang Jiang 750 is an old school bike. This is what gives it it's charm. However there are some situations where the old school parts can't |
|
 |
quite cut it. One of the more important items being.... The brakes.
Where as an unmodified stock Chang Jiang 750 works fine with the stock barrel brakes, it becomes a bit more serious when you find yourself on a high performace Chang Jiang doing 125 down Chang An Jie (don't do that by the way) this is when seriuos stopping power is needed and becomes more than necessary to have some high quality brakes that you can trust completely.
We have differernt solutions to suit all your stopping needs. The most effecient of course being the fluid disc brake or if you really mean business the double disc brake and/or |
the rear wheel disc brakes, double or single. Even though we are of the opinion that the CJ 750 is a cruiser, we have modified bikes with top speeds around 140 km/h (and we can make it go faster) |
|
We mount the disc brakes in such a way that you will still be able that all the bike wheels remain inter-changable. Meaning that you can still use your spare wheel with out dismantling the disc brake.
These disc brake babies are delivered complete with fluid container, tubes, wiring and grips. We have a wide selection of disc brakes to put on your Chang Jiang 750 and we HIGHLY recommend that you let us put them on. Nothing makes up a bad day than non working bike brakes.
If you are of the oppinion that disc brakes and classic bikes mix like oil and water, you might want to have a look at our high performace air cooled Triumph front brakes, they scream retro from here to He Bei. |

Triumph front brake and rim
An quan di yi..
Here is the solution for your High Performance CJ 750 when you want to keep it 'in style' |
|
 |
The '59 Triumph front brake. These are probably the best non-disc brakes avalable. The double leading brakes from a 59 Triumph offers exceptional stopping ability and they really do add a beautifull touch to your Chang Jiang 750.
Notice the air in-take that makes the brake stay 'cool' even under the highest pressure.
|
If you are riding a High Performance CJ you will need some serious stopping power. |
|
These brakes will deliver.
So if you really don't want your Chang Jiang fitted with the high performance disc brakes but still want to be sure that the bike stops when it's supposed to, this is the solution.
We have a bunch of these classic English brakes in stock, so pop by the shop, we will have them on your bike in no time.
And we do highly reccomend that you let us or other professionals put them on for you.

Alloy and alu wheels
Super durable alloy hubs and light weight sturdy aluminium hubs.
It kind of divides the Chang Jiang familly in two. To alloy or not to alloy that is the question. Maybe not the first choice if you want the classic look on your Chang Jiang 750. |
|
 |
However there are a few points and situations where we truely speak in favour of the cast alloy hubs. No more broken or bent spokes and easy maintanance are good pro-alloy points. And you have to admit they don't look half bad on this golden wonder.
Basically, if you do a lot of rough riding in the city, (like getting your bike over those monster sidewalk curbs so you can save 2 kuai in parking fee) or if you actually do a lot of real off-road riding, we recommend the alloy hubs.
Be very carefull if you get non-OEM alloys. Some are cheap low-quality that have been |
known to crack, snap and break especially in cold weather. Not a healthy situation...
We have a wide selection of alloy hubs and you can have them super polished or color- |
|
coated and modified in anyway you want.
If you want to retain the classic look of your Chang Jiang 750 you should go with the high quality aluminium hubs. Here you get a highly durable and very light weight wheel that is easy to maintain and naturally we can polish them up to shine like a high grade chrome job. Furthermore you can choose to have the hubs fitted with super strong and durable twined spokes. |

M5 wheels extra wide
Beef up your Chang Jiang 750 with a set of these monster wheels with extra wide rims.
The construction of the Chang Jiang 750 does not leave much room to experiment with fat |
|
 |
back wheels. The propeller shaft is simply sits too close to the wheel. However, we couldn't call ourselves a proper custom bikes shop if we couldn't hook you up sith a set of extra wide wheels, could we now...
The solution to your Fat Bob dreams are called M5. These monster hubs are also part of the military stock and they will last you a lifetime.
The M5 wheels are also a standard part of our WW II restoration bikes |
|
Now, seeing that there is a serious craving out there for bigger backwheels, we are currently working on a solution that will enable us to fit larger than standard hubs on the Chang Jinag 750. Keep yourself posted here and we will let you know as soon as we have some news on this big back wheel business. |

Slick racing tires
Racing tires might not the first thing that comes to mind when the talk falls on the Chang Jiang 750. But that just goes to show how much they know. When your CJ has been through a premium tune up at Beijing Sidecar you are going to be screaming for tires like these. |
|
 |
Even though The Chang Jiang 750 has been built to ride
in rough terrain, there is a world of difference between 1930's country roads and European battlegrounds, to the prime asphalt covering the high ways, biways and city boulevards of today.
So as road surface and tire |
|
grip demands change, we at Beijing Sidecar also change. |
|
We start by changing your tires so that your Chang Jiang 750 can meet the challenges and requirements of modern traffic and road grip.
These super slick, extra grip racing tires will glue your bike to the road. They will give more grip for improved accelaration and road control. Riding a CJ cruiser is going to be a whole lot more comfortable and cool once you get a set of these tires on her. |
|
|
|

|

|
|
|
 |
Head lights and fog lights
The stock Chang Jiang 750 comes with a 12 volt standard headlamp however most of our customers choose to have this replaced with a modern high power halogen head lamp. |
|
The holagen head lamp is far more
 |
powerfull than the regular head lamp bulb and it lasts longer. |
Halogen head lights come in a closed lamp or regular bulb version. Both types of halogen head lights come in a blue or white glass version. The blue glare version goes excellent with the high quality chrome. |
 |
|
|
Our fog lights are very popular. In an all chrome assembly it gives the bike a "Harley" look to the front end. More importantly they work and are extremely bright. Once you have tried riding at noght with the fog lights, you will never leave home without them. |
|
They can be painted any color as seen on our PLA CJ pages.
The stock head lamps come in chrome or black versions as standard. You can of course choose to have them colour-coated or super chromed so as |
|
|
to fit the look of your bike. |
|
|
|
|
|
|
|
|
|
|
 |
Tail and turn lights
Another important issue on constant debate among riders, what tail and turn light constellation to fit on your Chang Jiang 750 ? Ya, we know, they all look so good, how could you ever choose ?
|
|
 |
Unless you want something way out of the ordinary, stock options you two choices; big round tail light or the classic small square tail light. The turn lights are basically the same.
|
|
There is actually a third stock option. This is the newer version PLA standard 'all in one' super deluxe plastic combo solution'. Whether it looks nice on a CJ we will leave entirely up to you. |
|
|
|
|
|
|
|
|
|
 |
Miscelanious parts
Well, we have to stop at some point. Besides the menu can't fit any more items.
|
|
 |
Big fat M5 brak pedal, engine guard to protect your cylinder heads when off roading or from those nasty street curbs. Shock covers for your front fenders, braided stainless steel sheaths for protecting your hosing and wiring. |
|
You can have your wiring section connected for easy maintanance and all your electrical fitted into a practical small box that is hidden under the gas tank. |
|
 |
We are not usually the first to diss our own goods, but admitted, the stock speedometer leaves a bit to be desired. Why not have it replaced with a proper high quality speed O so you can see how fast you are actually going. |
|
 |
Also get som decent lighting in there. We have excellent quality speedometers. Mph or km/h or both, your choice. Come by and we will fit it on for you, no extra charge.
And then for all the rest... forget it. If there is any way it can go on your CJ we can fit it on for you. |
