Motor Package Set up Instructions 
CZPT aptitude is vital for productive installation. 
Most 24″ or 26″ bicycle with diamond body and a horizontal leading tube ought to have enough speed to 
mount the engine 
Stage one: The rear wheel sprocket shall be mounted very first! 
Remove the rear wheel from the bicycle. 
Remove the rear wheel sprocket and associated 
mounting components from the bag 
Slit one of the rubber washer as shown. This is to 
allow the rubber washer to go around the rear wheel 

Insert the rubber washers as shown 
Δ Mount the sprocket to the rear wheel as revealed. 
Δ Do not over-tighten and make confident that the 
sprocket is precisely perpendicular to the axis of 
the wheel. 
Δ Reinstall the rear wheel to bicycle.

Next: The Motor: 
The motor is created to in shape among the down tube and the seat tube of a CZPT diamond frame 
bicycle. Other types of bicycle might need slight modifications. 
Situation the motor so that when the exhaust silencer is mounted, it points in the direction of the floor nearly 
parallel to the down tube. 
The exhaust silencer needs to be removed to tighten the mounting nuts. 
So when positioning the motor, there is no want to tighten the exhaust silencer to the motor. 
Observe: If the bicycle body tubing is too big then you will have to use the bicycle frame adapter. 
(metal plate with three holes in the exact same plastic bag there are 3 bolts 2 that go into the motor and one 
longer 1 that goes by way of the bike frame then via the motor mount)

Up coming: CDI CZPTtrical Wiring Connections 

There have been several questions and confusion about how to set-up the wiring on a bicycle motor. 
The photograph underneath was despatched to me by a buyer of mine (thank you Dan) right after I had discussed to him 
how it should be done. I considering that questioned him if it would be alright to submit it up below for absolutely everyone to see 
due to the fact he did this kind of a wonderful occupation at drawing what I normally commit time creating. 
I would publish it out, but the photo is fairly a lot self-explanatory…if you nevertheless have concerns, make sure you let 
me know. 
As they say…”a picture is value a thousand terms” and in this situation it is. 
Upon observing this picture, an additional individual sent me the photograph under. Lyle hadn’t even positioned an order 
nevertheless when he despatched the picture that he manufactured, but he did get his CH80 a handful of days afterwards. It turned out very 
good and among these two images I will not consider it would be possible for anyone to have questions still 
…many thanks for the photo Lyle.

There have also been a number of folks out there that have lost their spark. This is usually thanks to excess 
moisture obtaining into the region of the coil…h2o and electricity will not mix effectively, lol. 
Given that several of us get time and satisfaction in possessing our wiring all wrapped up nice and quite I’ve posted 
the beneath images to present how the wiring connects onto the coil itself. 
It is a lot less difficult to strike the connections with a soldering iron to eliminate the wires from the coil, then 
remove the coil and re-attach the wires. A person has not too long ago accomplished this but couldn’t remember which 
wire went in which so now I have set photographs up to present so anyone must be able to do this. When you 
are putting the new coil in spot, it will help to use a piece of a business card among the magnet and 
the coil to maintain some slight spacing in there…do not overlook to get rid of it right after you have tightened down 
the coil even though.

Subsequent: Clutch 
Install clutch lever underneath still left manage brake lever. 
Operate cable down to motor. 
Insert warmth protecting spring (even bigger spring wire) above cable. 
Insert cable by way of anchor pivot. 
Insert spring return in excess of clutch cable. Tighten cable to clutch lever on motor, making certain that slack just . 
taken out 
The carburetor in the image bellow was taken out for clarity.

The completed installation ought to seem like this. 
Subsequent: Throttle 
Get rid of current appropriate deal with grip and substitute with twist throttle. 
Existing brake lever loosen and shifted to facilitate installation of twist throttle 
Substitute brake lever in its CZPT place right after installation of the twist throttle 
Subsequent: Gasoline tank 
Ultimately, mount the fuel tank more than the prime tube. 
Tighten the fuel valve to the tank. 
Reduce offer fuel line to duration and link fuel valve to carburetor.

Prepared to go 
Secure unfastened cables to frame of bicycle with cable tie (not accomplished in images). 
Fill fuel and lubricant combination in accordance with recommendation on the manual. 
Compress the clutch and start cycling bike as typical. When adequate speed is reached, launch the 
clutch. This will commence the engine. 
To cease, compress and have interaction the clutch lever. Brake as standard. 
To stop the motor, choke the carburetor completely with the lever on the carburetor. 
Alternatively, press the get rid of switch which is presented. When engine is not managing shut of gas valve 
1.Crucial: Remember to Study THIS: Fuel and Oil Mixture for Gas ratio 
The engine is a two cycle layout, as a result, a gasoline/oil combination is required. For the duration of the break-in 
interval (1st gallon of fuel), the ratio for 48cc is 25 parts gasoline to one component oil. Break in ratio for 80cc is 
twenty to one. Soon after the split-in period, the ratio is improved to thirty to 35 components gasoline to 1 portion oil. 
*Note: Use only Synthetic 2 Stroke Oil to insure suitable engine lubrication. 
Keep in mind safety 
1. Wipe up any spilled gas. Never ever fuel a hot engine or smoke whilst fueling. This could consequence in 
unexpected fireplace, private injury. Constantly transfer your motorized bicycle at minimum 10 toes from any fueling area 
ahead of attempting to begin it. In no way go away the tank gasoline cap off soon after fueling as rain drinking water will 
contaminate the gasoline and result in motor failure. 
two. Open the gas valve. Modest lever pointed down with gasoline line is in the open position. 
3. Depress the modest spherical cap plunger, ( Tickle button ), to primary carburetor. Situated on still left aspect of 
the carburetor following to the idle adjust screw. One particular or two moments is ample. 
4. Elevate choke lever to the upward position. This is the modest lever on the appropriate facet of the carburetor. 
All the way Up the choke is on. All the way Down the choke is off. Moveprogressively downward to 
off placement in the course of engine heat up period. 
five. Pull the handlebar clutch lever inward, to disengage the motor from the rear wheel. 
6. Pedal (down hill if possible for 1st commence) 
seven. Permit out the clutch lever all the way out and continuing to pedal. The outcome is a direct motor hook up 
with the rear wheel by way of chain and sprocket and the motor will now commence spinning, Pedal until motor 

commences. Accelerate gradually at 1st. 
eight. Twist throttle to improve pace, reverse twist throttle to reduce speed. To cease, disengage clutch 
and implement brakes. To accelerate, pedal and launch clutch even though opening throttle. 
9. Alter choke to the smoothest motor managing position. 
ten. Right after heat up press choke lever all the way down. If motor races as well quickly, or also sluggish, pull clutch 
lever and lock in the notched catch, end and change engine rpm. 
eleven. If the rpm needs modifying, switch the idle alter screw (left side of carburetor) in or out little by little to 
get the proper idle velocity of about 1400 rpm +/- 100 rpmTo properly crack the engine in, Do 
not exceed 15 mph or thirty min. continual operating for the very first fifty HangZhous for the duration of motor brake in. Engine 
will create far more power following break in. 
12. To end the motor, push Kill change and flip off fuel valve at tank. Turning off the gas will prevent 
gas from getting siphoned from tank. Warning Observe: By no means leave the tank gas valve in “open” place” 
when motor is not running or the bike is in storage. 
thirteen. Right after or before every journey examine all mounting fasteners, which includes high definition. bolts, axle and brakes. 
fourteen. Warning Be aware: Motor lock up or piston seizure because of to improper gas / oil combination will not be 
protected by manufacturing facility warranty. This the responsibility of the owner / operator to make confident the gas and 
oil is blended appropriately.
