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.
TYRES Only fi t tyres approved by BETAMOTOR. Unsuitable tyres can adversely affect the road holding of the vehicle. • To protect your safety, immediately re- place any damaged tyres. • Slick tyres adversely affect the road holding of the vehicle, especially on wet roads and in off-road riding.
HYDRAULIC CLUTCH CHECK OIL LEVEL To check the oil level in the clutch pump, fi rst 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 posi- tion, the level of the oil should be 5 mm below the upper rim.
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. • Rest the motor on a central stand, lift it making sure that it is stable. •...

• Loosen the counter-nut 2 and remove cap 1. • Extract the spring 3 and overturn the pipe, making the oil escape. • 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.
Page 43
• Tighten the cap to the completely ex- tended leg. • 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.
AIR FILTER A dirty air fi lter hinders the passage of air, reduces engine power and increases fuel consumption. For these reasons it is essen- tial to clean the air fi lter on a regular basis. Follow these steps to gain access to the air fi...
SPARK PLUG 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.
Page 46
Measure the spark gap with a thickness gauge. The gap should be 0.8÷0.9 mm. If the gap is not as specifi ed, restore the proper gap by bending the earth elec- trode. Check that the insulator is not cracked and that the electrodes are not corroded, in which case the spark plug should be immediately replaced.
CARBURETTOR CARBURETTOR WEAR GUIDELINES The throttle valve, the needle valve and the needle jet are subject to heavy wear due to engine vibrations. This can result in carburettor malfunctions (e.g. mixture enrichment). DRAINING THE CARBURETTOR FLOAT CHAMBER The carburettor float chamber can be drained by following the procedure de- scribed below while the engine is cold.
CHECKING THE FLOAT LEVEL (FLOAT HEIGHT) Remove the carburettor and the float chamber. Tilt the carburettor so that the fl oat touches the fl oat needle valve without pressing it too hard. In this position the fl oat edge should be parallel with the fl...
CHAIN DRIVE CHAIN MAINTENANCE The life of the drive chain largely depends on its maintenance. Chains without X- rings must be periodically cleaned in petroleum and then immersed in hot chain oil or treated with a chain spray. X-ring chains require very little maintenance. The best way to clean them is rinsing them generously with water.
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 fol- lowing procedures:...
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, fl exible cables, bearings, etc and can damage or destroy them. WARNING: Wash motorbikes frequently that are used near the sea (salty air) and on roads subject to salt spreading in winter.
PROLONGED INACTIVITY A few simple operations should be performed to keep the vehicle in good condition whenever it is to remain inactive for a long period (e.g. during the winter): • Thoroughly clean the vehicle. • Reduce the tyre pressures by approximately 30 percent, and if possible raise the tyres off the ground.

CHAPTER 4 ADJUSTMENTS CONTENTS Adjusting the home position of the front brake lever........56 Adjusting the home position of the brake pedal ........56 Adjusting the home position of the clutch lever ......... 56 Adjusting the handlebars ..............56 Gas control adjustment ................. 57 Checking and adjusting the steering play ..........
ADJUSTING THE HOME POSITION OF THE FRONT BRAKE LEVER The home position of brake lever 2 can be adjusted by means of screw 1. ADJUSTING THE HOME POSITION OF THE BRAKE PEDAL The home position of brake pedal 3 can be altered by turning adjusting screw 5 af- ter loosening the counternut located under dust cap 4.
GAS CONTROL ADJUSTMENT The throttle control cable should always have a 3-5 mm play. In addition, the idle speed should not change when the handle- bars are fully rotated to the left or right. Push back protective cap 10. Loosen counternut 11 and turn adjusting screw 12.
ADJUSTING FORK 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 anticlock- wise (towards the –...
SHOCK ABSORBER 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.
ADJUSTING THE HYDRAULIC REBOUND DAMPER Turn screw G to adjust the hydraulic re- bound damper. Turning the screw anticlockwise (out) de- creases the damping effect. Standard adjustment: 18 clicks from the completely closed position TENSIONING THE CHAIN To ensure the drive chain a longer life, it is advisable to periodically check its tension.
ADJUSTING THE IDLE SPEED 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.
Page 62
NOTE Failure to successfully complete the above procedure can be the result of an improp- erly 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.
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. FRONT Follow these steps to replace the pads: •Push the brake caliper towards the disc so that the pistons reach their home positions.
