5.2 ENGINE LUBRICATION SYSTEM

The gears of the oil pump are driven by the engine crankshaft. Pump gears rotate the plunger shaft in the oil pump. This shaft sends the lubricating oil into the crankcase to mix with the mixture of air-fuel flow evenly. The oil enters and covers the cylinder inner wall, piston surface, and piston rings.

¾ EXTERNAL OIL LEAKS ¾ WORN CYLINDER HEAD GASKET ¾ WORN PISTON RINGS

¾ PUMP NOT ADJUSTED PROPERLY ¾ OIL QUALITY IS BAD

5.3 CAUTION: Fuel/Oil Ratio

Having enough oil in the engine is very important. If the oil quantity is too low, the engine will be seriously scratched, likely seize, and possibly not work again.

When the cylinder wall is scored or scratched, replace the piston, piston rings, and cylinder together.

Check the combustion system and lubrication system carefully.

Beamer Rev-2.0.2 Page 21 of 55 11/21/2005

Page 22

www.Get2itParts.com

5.4 OIL PUMP

The quantity of oil that is delivered from oil pump increases with the engine speed and carburetor throttle width opening. The oil pump is located under the right side of the engine and connected by a control cable from the throttle. The throttle cable assembly splits into two cables with one end controlling the carburetor throttle cylinder and the other end controlling the quantity of oil delivered by the oil pump.

DISASSEMBLE OIL PUMP

Remove the helmet box. Disconnect the input and output oil tube. Unscrew the oil pump fixing bolts. Remove the oil pump.

INSPECT OIL PUMP

Check the matching side in the crankcase. Inspect the oil pump body. Inspect the gear part for damage. Inspect the O-ring for any leaks.

ASSEMBLE OIL PUMP

Apply grease on the O-ring and gear parts. Insert the oil pump into the engine crankcase. Fasten the fixing bolts. Torque value is 6 – 9 lbf-ft.

Beamer Rev-2.0.2 Page 22 of 55 11/21/2005

Page 23

www.Get2itParts.com

5.5 COOLING SYSTEM

The engine-cooling fan forces the air over the engine. The cooling fan is on the right side of engine. The air is forced to flow through cylinder fin and cylinder head. This prevents the cylinder and piston from overheating.

Disassemble the engine fan cover and cylinder plastic cover. Inspect the fan and cylinder fin. If the blades of the fan are broken, replace with a new fan.

7.4 AUTOMATIC CONTINUOUS VARIABLE TRANSMISSION

The transmission is a combination of an automatic centrifugal clutch and a V-belt continuous variable transmission, which can change the transmission ratio automatically.

When the engine speed increases, the drive pulley will push the belt by centrifugal force from the six rollers. Then, the pitch circle of belt in the drive pulley will be larger. The belt at the drive pulley is forced to move to the center of the shaft, and then the radius of pitch circle is decreased. The transmission ratio is therefore altered by the alteration of pitch circle's radius. (In the drawing, "H" means high speed; "L" means low speed)

7.5 CONTINUOUS VARIABLE TRANSMISSION

V-Belt

The belt is made of rubber fiber. It is resistant to heat, pressure, and abrasion. The inner side of the belt is toothed.

Drive Pulley

Due to increasing engine speed, the rollers push the movable drive face by centrifugal force. Then, the belt is pressed and enlarges its turning radius. The aluminum fan is installed on the exterior of the fixed drive face. It can reduce the belt temperature.

Driven Pulley

Because the revolving radius of the V-Belt at the drive end is enlarged, the Face Comp Movable Drive is squeezed out by the V-Belt at the driven end to shorten the revolving radius.

Beamer Rev-2.0.2 Page 31 of 55 11/21/2005

Page 32

www.Get2itParts.com

There is a Torque Cam on the Movable Drive Face. The torque Cam is loaded from the outside. When the outside load is higher than the engine's output, the pulley of the fixed shaft and belt slip to make the Movable Drive Face move along the inner side of the cam and compensate to increase to high torque (toward low speed) and make the engine maintain smooth running with original revolution.

7.6 TRANSMISSION BOX

The torque received by the drive shaft will be transmitted by the speed reduction of two sets to the rear axle shaft. The first gear ratio is 36/13. The second gear ratio is 48/12.

DISASSEMBLING THE TRANSMISSION BOX

1. Remove the exhaust pipe. Torque value: M6: 7 - 9 lbf-ft

M10: 25 – 29 lbf-ft

2. Unscrew rear axle nut and remove rear wheel.

3. Unscrew oil-drain bolt at the bottom of crankcase.

4. Let the oil flow out from transmission box.

5. Unscrew six bolts of transmission box cover.

6. Remove the transmission cover.

7. Remove the gears from transmission box.

Lubricating oil is SAE 80/90, 100cc/3.4oz.

7.7 ELECTRIC STARTER MOTOR

The Starter Motor is installed on the upper side of engine.

The starter motor can only be activated when the left hand brake is applied and the engine stop switch is in the run position.

7.8 KICK STARTER

The kick-starter arm is on the left side of engine. When the kick-starter arm is kicked, the gear of the starter shaft will drive the kick-starter to turn the crankshaft to start the engine. After the engine is started, the kick-starter will stop the transfer of power to the kick-starter driven gear. When the kick-starter lever is released, the kick-starter gear will go back to its original position.

11.4 BATTERY INSPECTION AND MAINTENANCE

CAUTION: The battery emits flammable and explosive fumes during normal operation. Keep away from sparks, open flame, and other possible sources of ignition. Always provide adequate ventilation during charging and maintenance of the battery. The battery contains sulfuric acid (an electrolyte). Contact with skin or eyes may cause severe burns or blindness. Always wear protective clothing and eye protection when servicing the battery. The electrolyte is toxic. If swallowed, drink large quantities of water or milk and seek medical attention immediately, or contact a poison control center.

The battery is located under the seat in the battery compartment.

Battery removal:

• Remove the battery retainer strap

• Disconnect the negative (BLACK) battery lead first

• Disconnect the positive (RED) battery lead next

• Use caution when disconnecting lead so as not to cause a spark

• Remove the battery from the battery compartment

Testing the battery:

• Measure the battery voltage using a multi-meter set to Voltage

• A fully charged battery should read 13.0-13.5V. An under charged or faulty battery will be below

12.0V.

• If the battery is showing under charge condition, charge the battery using a trickle charger at 7 amps for 10 hours. When charging the battery, it should be removed from the unit. Connect the charger lead to the battery before turning on the charging unit. Turn the charging unit off before disconnecting the charging leads from the battery. Retest the battery voltage. If the battery voltage shows an under charge condition after charging, replace the battery.

Beamer Rev-2.0.2 Page 50 of 55 11/21/2005

Page 51

www.Get2itParts.com

New battery preparation:

• The new battery is shipped dry with the electrolyte in a separate container. Remove the battery cell caps and install the electrolyte in the battery cells. CAUTION: Electrolyte contains sulfuric acid that can cause severe burns if contact is made with the skin or eyes. • Allow the battery to completely absorb the electrolyte (approximately one (1) hour). The battery should have a full charge. The battery is a gel acid battery and will not show any liquid electrolyte when fully absorbed.

DO NOT place the new battery on a charger as this can damage the cell plates and make the battery unusable.

Battery installation:

• Place the battery in the battery compartment.

• Clean the battery terminals and lead connectors of all dirt and corrosion.

• Attach the positive (RED) lead to the [+] positive terminal of the battery first.

• Attack the negative (BLACK) lead to the [-] negative terminal of the battery next.

• Check the lead routing to ensure they are clear of obstruction and do not fall between the battery and unit body where they could be abraded or otherwise damaged.

• Attach the battery retainer strap to secure the battery in place.

Battery charging:

• If the battery become discharged or shows low voltage you can recharge the battery using a 12 volt battery trickle charger.

• Connect the positive lead of the charger to the positive terminal of the battery.

• Connect the negative lead of the charger to the negative terminal of the battery.

• Turn on the charger and allow the battery to charge from 4 to 6 hours.

• Test the battery voltage after charging it should give a reading of between 12-and 13 volts.

• If after charging the battery is still indication a low voltage or the battery will not hold the charge for more than a day or two the battery should be replaced. ETON recommends replacing the battery every two years for optimal performance.

Beamer Rev-2.0.2 Page 51 of 55 11/21/2005

Page 52

www.Get2itParts.com

Battery Storage:

If the vehicle will not be in use for an extended period of time, the battery should be removed and stored in a location that will ensure that battery will not freeze.

DO NOT store the battery on a concrete surface as it can draw the charge from the battery and damage the battery plates.

11.5 STARTER MOTOR

The starter motor is attached to the engine. Unscrew the two starter motor fixing Bolts and remove the starter motor. Disconnect the motor wire. Connect motor and battery to check the functionality of the motor.
