Note: A joint binder may be needed on both sides of the sprocket for chain alignment on some non-coaster brake bikes. ![]()
STEP 10. Place the brake arm in a vise (heat will make bending easier and more precise). A hammer and brute force will work in this application as well. STEP 11. After the bend is complete, install the brake arm and spin the wheel to check for clearance. If the arm clears the bolts, attach the wheel to the bike and get ready to install your motor.
STEP 12. Now that you have installed the rear wheel and checked to see that it spins true, it‘s time to move on to the motor. Note: There are many ways to install your motor and people are coming up with new mounting ideas every day. We will be touching on a few different ones. Rear Engine InstallationSection 2 Installing the motorAfter installing the sprocket to the rear wheel and placing the rear wheel on the bike, Attach the chain tensioner to the left side of the bike on the rear upper frame rail as shown. Don‘t tighten the tension wheel yet. That will be tightened after the chain is installed. ![]()
Take out the 2 long screws, 2 flat bar with nuts and one black thick bar and assemble the long screw to the flat bar as shown, tighten it with the nut to lock it in place.
Unscrew the nut from the bicycle at the rear wheel axle, place the flat bar onto the axle then replace the nut as shown. Be sure that the flat bar is in front of the bolt on the derailleur or the engine will not sit securely on the mount. ![]() ![]() ![]() ![]() ![]()
Remove the master link from the chain and slide it over the sprocket behind the small chain. Master Link
Let the chain hang down to the wheel sprocket it should line up straight. Wrap the chain around the wheel sprocket and replace the master link. If the sprocket is straight and the chain length is good you may choose not to use the chain tensioner. Adjust the tensioner wheel to remove slack in the chain and tighten in place.
If you need to slide the motor to the left or right to line up the sprockets loosen these two bolts and
If you need to adjust the chain tension on the small chain, slightly loosen the bolts on the drive housing. Then raise or lower the T-bolt under the Motor. ![]() ![]() ![]() ![]() GENERAL SAFETY PRECAUTIONS
10.Check local and state laws before riding your MOTOcycle on the street. 11.WARNING“ ALWAYS WEAR A HELMET WHILE RIDING!! PREPARATION1. Engine oil level CAUTION! Running the engine with insufficient oil can cause serious engine damage. Be sure to check the engine on a level surface with the engine stopped.
Every 10 hours check the oil level and replenish the oil up to the top of the filler neck if the engine is operated for more than 10 hours continuously. Use a high detergent, premium quality motor oil certified to meet or exceed U.S. automobile manufacture‘s requirement for service classification SG. SF. Motor oils classified SG, SF will show this designation on the container. SAE 10W-30 is recommended for general, all temperature use. CAUTION!! Using non-detergent oil or 2 stroke engine oil shorten the engine‘s life. 2. Air cleaner CAUTION!! Never run the engine without the air cleaner. Rapid engine wear will result. Check cleaner for dirt or obstruction of element.
3. Fuel Use automotive gasoline (unleaded or lowleaded is preferred to minimize combustion chamber deposits). Never use an oil / gasoline mixture or dirty gasoline. Avoid getting dirt, dust or water in the fuel tank. WARNING!! Gasoline is extremely flammable and is explosive under certain conditions. Refuel in a well-ventilated area with the engine stopped. Don‘t smoke or allow flames or sparks in the area where the engine is refueled or where the engine is stored. Don‘t overfill the tank (there should be no fuel in the filler neck). After refueling, make sure the tank cap is closed properly and securely. Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before starting the engine. Avoid repeated or prolonged contact with skin or breathing vapor.
KEEP OUT OF REACH OF CHILDREN. Fuel tank capacity: 0.9 1 (0.238 US gal) GASOLINE CONTAINING ALCOHOL If you decide to use a gasoline containing alcohol (gasohol), be sure it‘s octane rating is high. There are two types of —gasohol“, one containing alcohol, and the other containing methanol. Don‘t use gasoline containing methanol (methyl or wood alcohol that does not also contain co-solvents and corrosion inhibitors for methanol. Never use gasoline containing more than 5% methanol, even if it has co-solvents and corrosion inhibitors. CAUTION!
4. Retightening bolts and nuts: Check for loose bolts and nuts. Tighten the bolts and nuts properly and securely, if necessary. V. STARTING THE ENGINE
CAUTION! Don‘t use the choke if the engine is warm or the air temperature is high.
CAUTION! If not pulled briskly, sparks may fail to jump across the spark plug electrodes, resulting in failure to start the engine. • High altitude operation At high altitude, the standard carburetor air-fuel mixture will be excessively rich. Performance will decrease, and fuel consumption will increase. High altitude performance can be improved by installing a smaller diameter main fuel jet in the carburetor, and readjusting the idle needle screw. If you always operate the engine at altitudes higher than 1,860m (6000 feet) above sea level, have your authorized dealer perform these carburetor modifications. Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5% for each 305m (1000 feet) increase in altitude. The affect of altitude on horsepower will be greater than this if no carburetor modification is made. CAUTION! Operation of the engine at an altitude lower than the carburetor is jetting for may result in reduced performance, overheating, and serious engine damage caused by an excessively lean air/fuel mixture. VI. OPERATION
VII. STOPPING THE ENGINETo stop the engine in an emergency, turn the engine switch to the OFF position (on the equipment side). Under normal conditions, use the following procedure.
VIII. MAINTENANCEPeriodic inspection and adjustment of the engine is essential if high lever performance is to be maintained. Regular maintenance will also ensure a long service life. The required service intervals and the kind of maintenance to be performed are described on the table below. Maintenance Scedule
Service more frequently if used in a dirty area. These items should be serviced by an authorized dealer, unless the owner has the proper tools and mechanical proficiency. WARNING!
CAUTION! Use only genuine parts or their equipment. The use of replacement parts which are not equivalent quality may damage the engine. 1. Oil Change Drain the oil while the engine is still warm to assure rapid and complete drain.
Engine oil capacity: 0.101 (0.11 US qt. 0.09 Imp qt.) Wash your hands with soap and water after handling used oil. CAUTION! Please dispose of used motor oil in a manner that is compatible with the environment. We suggest you take it in a sealed container to your local service station for reclamation. Don‘t throw it in the trash or pour it on the ground. 2. Air cleaner service A dirty air cleaner will restrict air flow to the carburetor. To prevent carburetor malfunction, service the air cleaner regularly. Service more frequently when operating the engine in extremely dusty areas. WARNING! Never use gasoline or low flash point solvents for cleaning the air cleaner element. A fire or explosion could result. CAUTION! Never run the engine without the air cleaner. Rapid engine wear will result.
3. Spark plug service Recommended spark plug: C5HSB CR5HSB (NGK) CAUTION! Never use a spark plug of incorrect heat range. To ensure proper engine operation, the spark plug must be properly gapped and free of deposits. a. Remove the spark plug cap and use the proper size spark plug wrench to remove the spark plug. WARNING! If the engine has been running, the muffler will be very hot. Be careful not to touch the muffler.
C AUTION! When installing a new spark plug, tighten with ² turn after the spark plug seats to compress the washer. When reinstalling a used spark plug, tighten 1/8 to ³ turn after the spark plug seats to compress the washer. CAUTION! The spark plug must be securely tightened. An improperly tightened spark plug can become very hot and may damage the engine. 4. Fuel filler service WARNING! Gasoline is extremely flammable and is explosive under certain conditions. Don‘t smoke or allow flames or sparks in the area.

We offer these instructions to guide you through the installation. Please read through the instructions before beginning your installation. Happy motoring! Accessory Kit InstallationStep 1. Mounting the Headlight The headlight bracket included in your kit is mountable on the front fork. You can mount it above or below the wheel line. Be sure to give yourself room for the spokes. Shown here installed below the wheel line.
Step 2. If you prefer an alternative to the front fork placement, you can easily make your own bracket out of a steel or aluminum bar purchased from your local hardware store.
Step 6. Decide where on your bike you want the light installed. You can easily install the headlight on the handlebars by bending your newly fashioned bracket around the bar, and drilling another hole that lines up with the hole drilled in step five.
Step 7. If you prefer, you could bend the bracket into an —L“ shape and mount it to the front fork, above the wheel and behind the brake caliper. The light installs easily and does not affect the braking of the bike. Note: Most bicycle forks have a hole for a front brake caliper even if there is no brake caliper. ![]() ![]()
Step 12. Programming the Computer Press and hold the button on the front for 3 seconds; then let the button up. Choose between —kph“ or —mph“ by pressing the button. The display will change each time the button is pressed. When your choice shows on the display, press and hold the button for three seconds and release. Now you must calibrate the wheel.
