mount the engine 
Action 1: The rear wheel sprocket shall be mounted initial! 
Remove the rear wheel from the bicycle. 
Sprocket: 
Eliminate the rear wheel sprocket and associated 
mounting equipment from the bag 
Slit a single of the rubber washer as demonstrated. This is to 
enable the rubber washer to go close to the rear wheel 
shaft.

Insert the rubber washers as shown 
Δ Mount the sprocket to the rear wheel as proven. 
Δ Do not more than-tighten and make positive that the 
sprocket is exactly perpendicular to the axis of 
the wheel. 
Δ Reinstall the rear wheel to bicycle. 
Up coming: The Carburetor 
Remove valve system from the carburetor. 
Insert throttle cable through screw cap. Insert spring return and connected conclude of cable to valve plunger. 
Line up the cable and spring. 
Run cable down to engine Replace earlier mentioned mechanism into the carburetor.

Up coming: The Engine: 
The motor is developed to match between the down tube and the seat tube of a regular diamond frame 
bicycle. EPT kinds of bicycle might demand slight modifications. 
Position the engine so that when the exhau EPT silencer is set up, it points in the direction of the floor nearly 
parallel to the down tube. 
The exhau EPT silencer demands to be removed to tighten the mounting nuts. 
So when positioning the motor, there is no need to tighten the exhau EPT silencer to the engine. 
Be aware: If the bicycle body tubing is too big then you will have to use the bicycle frame adapter. 
(steel plate with 3 holes in the same plastic bag there are 3 bolts 2 that go into the motor and one 
more time 1 that goes by way of the bicycle frame then through the motor mount)

As proven on photographs below

Following: CDI Electrical Wiring Connections 

There have been a lot of questions and confusion about how to established-up the wiring on a bicycle motor. 
The photo under was despatched to me by a consumer of mine (thank you Dan) soon after I had discussed to him 
how it ought to be completed. I considering that questioned him if it would be alright to po EPT it up right here for absolutely everyone to see 
simply because he did this kind of a great task at drawing what I typically spend time producing. 
I would create it out, but the image is quite much self-explanatory…if you even now have questions, make sure you let 
me know. 
As they say…”a picture is really worth a thousand words and phrases” and in this case it is. 
Upon looking at this photo, an EPT man or woman sent me the picture beneath. Lyle hadn’t even placed an order 
yet when he despatched the image that he manufactured, but he did get his CH80 a couple of days later on. It turned out very 
good and among these two photographs I will not feel it would be achievable for anyone to have concerns still 
…thanks for the picture Lyle.

There have also been a few individuals out there that have lo EPT their spark. This is normally because of to excess 
moisture getting into the region of the coil…water and electric power don’t combine effectively, lol. 
Considering that a lot of of us take time and pride in possessing our wiring all wrapped up great and quite I have posted 
the below images to demonstrate how the wiring connects onto the coil by itself. 
It is a great deal simpler to strike the connections with a soldering iron to remove the wires from the coil, then 
get rid of the coil and re-attach the wires. Someone has lately carried out this but could not recall which 
wire went the place so now I’ve set images up to show so anybody should be able to do this. When you 
are putting the new coil in spot, it will help to use a piece of a company card between the magnet and 
the coil to maintain some slight spacing in there…do not overlook to remove it following you’ve tightened down 
the coil however.

Following: Clutch 
Set up clutch lever below remaining manage brake lever. 
Operate cable down to motor. 
Insert heat protective spring (larger spring wire) over cable. 
Insert cable by way of anchor pivot. 
Insert spring return in excess of clutch cable. Tighten cable to clutch lever on motor, guaranteeing that slack ju EPT . 
taken out 
The carburetor in the photograph bellow was taken out for clarity.

The completed installation need to search like this. 
Next: Throttle 
Eliminate current proper take care of grip and replace with twi EPT throttle. 
Present brake lever loosen and shifted to aid installation of twi EPT throttle 
Exchange brake lever in its original placement after installation of the twi EPT throttle 
Up coming: Gas tank 
Ultimately, mount the fuel tank over the leading tube. 
Tighten the fuel valve to the tank. 
Reduce offer gas line to size and join gas valve to carburetor.

Ready to go 
Protected free cables to frame of bicycle with cable tie (not completed in photos). 
Fill gasoline and lubricant combination in accordance with suggestion on the handbook. 
Compress the clutch and begin cycling bicycle as typical. When enough velocity is arrived at, launch the 
clutch. This will start off the motor. 
To cease, compress and interact the clutch lever. Brake as normal. 
To cease the motor, choke the carburetor totally with the lever on the carburetor. 
Alternatively, push the kill change which is supplied. When engine is not managing shut of fuel valve 
fully. 
one.Important: You should RE EPT THIS: Gasoline and Oil Mixture for Gasoline ratio 
The engine is a 2 cycle layout, for that reason, a gasoline/oil combination is necessary. For the duration of the crack-in 
time period (1 EPT gallon of gas), the ratio for 48cc is twenty five elements gasoline to 1 part oil. Crack in ratio for 80cc is 
twenty to 1. Following the break-in period of time, the ratio is elevated to thirty to 35 components gasoline to 1 portion oil. 
*Be aware: Use only Synthetic 2 Stroke Oil to insure suitable engine lubrication. 
!WARNING! 
Don’t forget safety 
one. Wipe up any spilled gas. Never ever gas a scorching engine or smoke although fueling. This could outcome in

contaminate the gas and lead to motor failure. 
2. Open up the gasoline valve. Little lever pointed down with gasoline line is in the open up situation. 
3. Depress the tiny spherical cap plunger, ( Tickle button ), to prime carburetor. Located on still left aspect of 
the carburetor up coming to the idle adju EPT screw. 1 or two times is ample. 
four. Elevate choke lever to the upward situation. This is the little lever on the appropriate side of the carburetor. 
All the way Up the choke is on. All the way Down the choke is off. Moveprogressively downward to 
off situation for the duration of engine warm up time period. 
five. Pull the handlebar clutch lever inward, to disengage the motor from the rear wheel. 
six. Pedal (down hill if achievable for fir EPT commence) 
7. Allow out the clutch lever all the way out and continuing to pedal. The outcome is a direct motor hook up 
with the rear wheel through chain and sprocket and the engine will now commence spinning, Pedal right up until motor 

starts. Speed up slowly and gradually at 1st. 
8. Twi EPT throttle to increase velocity, reverse twi EPT throttle to decrease pace. To quit, disengage clutch 
and utilize brakes. To speed up, pedal and release clutch while opening throttle. 
nine. Adju EPT choke to the smoothe EPT engine managing placement. 
10. Right after heat up thrust choke lever all the way down. If engine races too rapidly, or too gradual, pull clutch 
lever and lock in the notched capture, cease and adju EPT motor rpm. 
eleven. If the rpm wants adjusting, change the idle adju EPT screw (left aspect of carburetor) in or out gradually to 
get the correct idle pace of about 1400 rpm +/- one hundred rpmTo appropriately split the motor in, Do 
not exceed fifteen mph or 30 min. continuous operating for the fir EPT 50 HangZhous throughout motor brake in. Engine 
will create more energy right after split in. 
12. To stop the engine, thrust Destroy switch and change off gas valve at tank. Turning off the gasoline will prevent 
gas from currently being siphoned from tank. Warning Observe: In no way leave the tank gas valve in “open up” position” 
when motor is not operating or the bike is in storage. 
thirteen. Right after or ahead of every single experience check out all mounting fasteners, which includes high definition. bolts, axle and brakes. 
fourteen. Warning Note: Engine lock up or piston seizure due to incorrect gasoline / oil combination will not be 
coated by factory warranty. This the responsibility of the operator / operator to make confident the gas and 
oil is blended appropriately.
