CHECKS AND MAINTENANCE A 1 2 WARNING We recommend using DOT 4 brake fluid. Should this fluid be unavailable, use DOT 5.1 fluid instead. Do not on any account use DOT 5 brake fluid. This is a purple fluid with a base of silicone oil which requires special seals and tubes. WARNING The brake fluid is extremely corrosive.
3 CHECK THE LEVEL OF THE REAR BRAKE FLUID Check the level of the brake fluid through sight D. The level of the fluid should never fall below the mark in the sight. 3 D WARNING We recommend using DOT 4 brake fluid. Should this fluid be unavailable, use DOT 5.1 fluid instead. Do not on any account use DOT 5 brake fluid. This is a purple fluid with a base of silicone oil which requires special seals and tubes. WARNING The brake fluid is extremely corrosive. Take care not to spill it on the paintwork.
3 FRONT BRAKE LINING CONTROL In order to verify the wear condition of front brake is enough to view the pincer from the bottom, where is possible to glimpse the brake lining tails which will have to show a brake of 2 mm in thickness. If the stratum is lesser let’s start replacing them. CHECKS AND MAINTENANCE Note Perform the check according to the times shown in the table on page 52.
Only fit tyres approved by BETAMOTOR. Unsuitable tyres can adversely affect the road holding of the vehicle. • To protect your safety, immediately replace any damaged tyres. • Slick tyres adversely affect the road holding of the vehicle, especially on wet roads and in off-road riding. • Insufficient pressure results in abnormal wear and overheating of the tyres. • The front and rear tyres must have the same tread design. • Always measure the inflating pressures when the tyres are cold.
3 1 CHECKS AND MAINTENANCE 2 HYDRAULIC CLUTCH CHECK OIL LEVEL To check the oil level in the clutch pump, first remove cover 2. Remove the two screws 1 and take off cover 2 together with the rubber bellows. With the clutch pump in a horizontal position, the level of the oil should be 5 mm below the upper rim. If necessary top up with (DOT 5.1) hydraulic oil, which is available from your BETAMOTOR dealer. Use the liquid indicated on page 24 in the “Recommended lubricants and liquids” table.
3 FORK OIL Right/left-hand rod The procedure for changing the oil in the forks is provided only for information. We recommend having the operation performed by a BETAMOTOR authorized workshop. A • Remove the cable gland U-bolt A • Remove the screws B that fix the brake caliper to the left leg and remove the brake caliper. D • Remove cap C, loosen the screws D, slide the wheel pin out and remove the front wheel.
3 • Loosen the counter-nut 2 and remove cap 1. 1 CHECKS AND MAINTENANCE 2 • Extract the spring 3 and overturn the pipe, making the oil escape. 3 • Move the pumping unit and drain the remaining oil. When the oil has been drained completely, introduce the amount of new oil described in chapter 1. 1 • Bleed the pumping unit of air, making it rise and fall until complete loading. Introduce the spring and screw the cap 1 until it is completely inserted on the pumping rod.
3 • Insert the legs into the plates. Once the leg has been positioned at the desired extension, tighten screws E at 17Nm and F at 12Nm, after the screws have been greased. CHECKS AND MAINTENANCE • Tighten the cap to the completely extended leg. E 17Nm 12Nm F • Apply the wheel complete with spacers, pin and cap C, which will be tightened to 50Nm. Tighten the screws D to 10Nm. Apply the brake caliper and apply threadlock of average intensity onto screws B. Tighten to 35Nm.
3 AIR FILTER CHECKS AND MAINTENANCE A dirty air filter hinders the passage of air, reduces engine power and increases fuel consumption. For these reasons it is essential to clean the air filter on a regular basis. 1 Follow these steps to gain access to the air filter. •Pull the cover air filter. •Release filter fastener 1. •Soundproof shell removal •Pull out air filter 2. •Carefully wash the filter with soap (or special detergent) and water. •Dry the filter.
SPARK PLUG A To accede to spark plug, is necessary to take off saddle and the fuel tank. To remove the fuel tank proceed as follows. Unscrew the two screws A, unscrew the screw B (both side). Close the fuel tap (OFF position) and disconnect the pipe fuel C from the fuel tap. Keeping the spark plug in good condition makes for reduced consumption and optimum engine performance.
3 Measure the spark gap with a thickness gauge. The gap should be 0.8÷0.9 mm. If the gap is not as specified, restore the proper gap by bending the earth electrode. CHECKS AND MAINTENANCE Check that the insulator is not cracked and that the electrodes are not corroded, in which case the spark plug should be immediately replaced. USA Conduct the check by referring to the table on page 52.
3 CARBURETTOR CARBURETTOR WEAR GUIDELINES DRAINING THE CARBURETTOR FLOAT CHAMBER The carburettor float chamber can be drained by following the procedure described below while the engine is cold. Close the fuel cock and place tube 4 in a container to gather the fuel that flows out. Open drain screw 5 and drain the fuel. Close the drain screw, open the fuel cock and check the seal of the system. 5 4 WARNING Fuel is flammable and toxic and must be handled with great care.
CHECKS AND MAINTENANCE 3 CHECKING THE FLOAT LEVEL (FLOAT HEIGHT) 3 Remove the carburettor and the float chamber. Tilt the carburettor so that the float touches the float needle valve without pressing it too hard. In this position the float edge should be parallel with the float chamber sealing surface (see figure). If the float height does not correspond to the nominal value, check the float needle valve and if necessary replace it.
3 CHAIN DRIVE CHAIN MAINTENANCE Take special care in preventing the lubricant from coming into contact with the rear tyre or brake disc, otherwise the tyre grip and the action of the brake would be greatly reduced, making it very difficult to control the vehicle. DRIVE CHAIN WEAR To check the wear of the drive chain use the procedure described below. Shift into neutral, pull up the upper stretch of the chain with a force of 10 - 15 kg (see figure).
CHECKS AND MAINTENANCE 3 USA BATTERY CHARGING THE BATTERY Remove the battery and check its charge. Using an open-circuit multimeter (10-12 hours after the activation), check that the voltage is greater than 12.6 V. If it is lower, it is advisable to recharge the battery. Based on the type of charger available, charge the battery using either of the following procedures: • Constant voltage (14.4-15 V) - Charge the battery for about 12 hours.
CLEANING THE VEHICLE WARNING: Do not clean your vehicle with a high-pressure device with a strong jet of water. Excessive pressure can reach electrical components, connectors, flexible cables, bearings, etc and can damage or destroy them. 3 When cleaning, avoid direct exposure to sunlight. Close off the exhaust system to prevent water from entering. Use water jet to soften the dirt and mud accumulated on the paintwork, then remove them with a soft bodywork sponge soaked in water and shampoo.

4 ADJUSTING THE HOME POSITION OF THE FRONT BRAKE LEVER The home position of brake lever 2 can be adjusted by means of screw 1. 1 2 ADJUSTING THE HOME POSITION OF THE BRAKE PEDAL ADJUSTMENTS 3 The home position of brake pedal 3 can be altered by turning adjusting screw 5 after loosening the counternut located under dust cap 4. Loosen the counternut and turn the adjusting screw until the desired height is obtained. Retighten the counternut after completing the operation.
10 11 12 The throttle control cable should always have a 3-5 mm play. In addition, the idle speed should not change when the handlebars are fully rotated to the left or right. Push back protective cap 10. Loosen counternut 11 and turn adjusting screw 12. Turning the screw anticlockwise decreases the idle travel; turning it clockwise increases it. Tighten the counternut and check that the throttle twist grip turns smoothly.
4 ADJUSTING FORK A ADJUSTING THE REBOUND DAMPER The hydraulic rebound damper determines the behaviour of the telescopic fork during extension and can be adjusted by means of screw A. Turning the screw clockwise (towards the + sign) increases the action of the rebound damper; turning it anticlockwise (towards the – sign) decreases the action of the rebound damper.
ADJUSTING THE HYDRAULIC COMPRESSION DAMPER (HIGH AND LOW SPEEDS) The shock absorber can be adjusted for both high and low speeds. The terms ‘high’ and ‘low’ refer to the compression speed of the shock absorber, not to the speed of the vehicle. The low-speed adjustment affects the behaviour of the shock absorber during low-speed compression; conversely the high-speed adjustment affects its behaviour during high-speed compression.
4 ADJUSTING THE HYDRAULIC REBOUND DAMPER Turn screw G to adjust the hydraulic rebound damper. Turning the screw anticlockwise (out) decreases the damping effect. G Standard adjustment: 18 clicks from the completely closed position ADJUSTMENTS TENSIONING THE CHAIN To ensure the drive chain a longer life, it is advisable to periodically check its tension. Always maintain the chain clean and lubricated. If the chain play exceeds 30÷35 mm, tension the chain by following these steps.
1 Engine starting is strongly affected by the idle speed adjustment. In other words, an engine whose slow running is properly adjusted is easier to start than an engine with an unsuitably tuned up engine. The idle speed is adjusted by means of adjusting knob 1 and mixture adjusting screw 2. The adjusting knob regulates the base position of the throttle valve. By turning the knob clockwise increases the rotation speed and counter-clockwise to lower it.
4 NOTE Failure to successfully complete the above procedure can be the result of an improperly sized idling jet. a) If the mixture adjusting screw is turned until it stops and no changes in the idle speed are observed, a smaller idling jet is required. b) If the engine stalls when the adjusting screw is still two turns open, a larger idling jet is needed. Naturally, after replacing the jet the adjusting procedure will have to be restarted from the beginning.

5 REPLACING THE BRAKE PADS The procedure for replacing the brake pads is provided only for information. We recommend having the operation performed by a BETAMOTOR authorized workshop. REPLACEMENTS A USA B FRONT Follow these steps to replace the pads: •Push the brake caliper towards the disc so that the pistons reach their home positions. •Unscrew dowel A. •Pull out pin B, while supporting the two pads as shown in the figure.
5 REAR Follow these steps to replace the pads: WARNING The brake disc must always be kept free from oil and grease. An oily or greasy disc strongly reduces the braking action. After work has been carried out on the braking system, pull the brake lever to bring the pads into contact with the disc. This will allow the correct pressure point to be restored, thus ensuring proper operation of the braking system.
5 2 REPLACING THE HEADLIGHT BULBS Release both spring washers and move forward the lamp holder front cowl. 1 3 Carefully remove the headlight bulb 1 together with lamp holder. To replace the high beam / low beam, lift the rubber cover 2, release connector, push on the spring 3 and remove the lamp holder and replace the light bulb with a new one. Be careful not to touch the bulb so as not to compromise its efficiency. REPLACEMENTS To refit, follow the procedure above but in reverse order.
