Mechanical aptitude is crucial for profitable installation. 
Mo EPT 24″ or 26″ bicycle with diamond body and a horizontal prime tube must have sufficient speed to 
mount the engine 
Step 1: The rear wheel sprocket shall be mounted very first! 
Eliminate the rear wheel from the bicycle. 
Sprocket: 
Remove the rear wheel sprocket and associated 
mounting accessories from the bag 
Slit one particular of the rubber washer as demonstrated. This is to 
permit 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 shown. 
Δ Do not over-tighten and make sure that the 
sprocket is precisely perpendicular to the axis of 
the wheel. 
Δ Reinstall the rear wheel to bicycle. 
Up coming: The Carburetor 
Take away valve mechanism from the carburetor. 
Insert throttle cable through screw cap. Insert spring return and connected finish of cable to valve plunger. 
Line up the cable and spring. 
Run cable down to motor Substitute earlier mentioned system into the carburetor.

Following: The Motor: 
The engine is developed to suit in between the down tube and the seat tube of a normal diamond frame 
bicycle. EPT sorts of bicycle may need slight modifications. 
Situation the motor so that when the exhau EPT silencer is mounted, it points in the direction of the ground nearly 
parallel to the down tube. 
The exhau EPT silencer demands to be taken off to tighten the mounting nuts. 
So when positioning the motor, there is no need to have to tighten the exhau EPT silencer to the motor. 
Observe: If the bicycle body tubing is way too large then you will have to use the bicycle frame adapter. 
(metallic plate with 3 holes in the exact same plastic bag there are 3 bolts 2 that go into the motor and one 
for a longer time a single that goes through the bike body then by way of the motor mount)

As proven on photographs below

Next: CDI Electrical Wiring Connections 

There have been several queries and confusion about how to established-up the wiring on a bicycle motor. 
The photo underneath was sent to me by a consumer of mine (thank you Dan) following I had discussed to him 
how it should be completed. I given that asked him if it would be alright to po EPT it up listed here for everybody to see 
since he did these kinds of a great work at drawing what I usually commit time producing. 
I would compose it out, but the image is fairly significantly self-explanatory…if you even now have queries, please let 
me know. 
As they say…”a image is value a thousand words and phrases” and in this case it is. 
On looking at this photograph, an EPT man or woman sent me the picture below. Lyle hadn’t even put an order 
nevertheless when he despatched the picture that he created, but he did get his CH80 a couple of days later. It turned out very 
great and in between these two photos I will not feel it would be possible for any individual to have inquiries still 
…thanks for the picture Lyle.

There have also been a few people out there that have lo EPT their spark. This is usually due to excess 
moisture acquiring into the area of the coil…water and electrical energy will not mix well, lol. 
Because numerous of us consider time and pride in getting our wiring all wrapped up good and rather I’ve posted 
the underneath photographs to display how the wiring connects on to the coil itself. 
It is a lot less difficult to strike the connections with a soldering iron to get rid of the wires from the coil, then 
eliminate the coil and re-connect the wires. Someone has just lately done this but couldn’t remember which 
wire went in which so now I’ve place pictures up to display so any individual need to be in a position to do this. When you 
are placing the new coil in area, it assists to use a piece of a enterprise card between the magnet and 
the coil to keep some slight spacing in there…do not forget to remove it soon after you’ve got tightened down 
the coil although.

Following: Clutch 
Set up clutch lever below left handle brake lever. 
Run cable down to motor. 
Insert heat protecting spring (greater spring wire) in excess of cable. 
Insert cable by way of anchor pivot. 
Insert spring return above clutch cable. Tighten cable to clutch lever on engine, making sure that slack ju EPT .

5. Pull the handlebar clutch lever inward, to disengage the engine from the rear wheel. 
six. Pedal (down hill if possible for fir EPT commence) 
seven. Permit out the clutch lever all the way out and continuing to pedal. The outcome is a immediate motor hook up 
with the rear wheel via chain and sprocket and the motor will now commence spinning, Pedal until finally motor 

starts. Speed up slowly and gradually at very first. 
8. Twi EPT throttle to increase speed, reverse twi EPT throttle to decrease speed. To quit, disengage clutch 
and utilize brakes. To accelerate, pedal and launch clutch while opening throttle. 
9. Adju EPT choke to the smoothe EPT engine operating place. 
10. After heat up push choke lever all the way down. If engine races also fast, or too sluggish, pull clutch 
lever and lock in the notched capture, quit and adju EPT engine rpm. 
eleven. If the rpm requirements adjusting, change the idle adju EPT screw (left side of carburetor) in or out slowly and gradually to 
get the proper idle velocity of about 1400 rpm +/- one hundred rpmTo properly split the engine in, Do 
not exceed 15 mph or thirty min. continuous managing for the fir EPT 50 HangZhous in the course of engine brake in. Engine 
will produce far more power soon after split in. 
12. To end the engine, drive Kill change and change off fuel valve at tank. Turning off the gas will prevent 
gasoline from being siphoned from tank. Warning Observe: Never leave the tank gas valve in “open up” placement” 
when motor is not running or the bike is in storage. 
thirteen. Right after or before every single experience examine all mounting fasteners, like hd. bolts, axle and brakes. 
fourteen. Warning Notice: Engine lock up or piston seizure because of to incorrect gas / oil combination will not be 
covered by factory warranty. This the obligation of the operator / operator to make positive the gas and 
oil is combined appropriately.
