User manual APRILIA RX 50 RACING 2003

[. . . ] Racing 8202401 CATALYTIC MUFFLER USE ONLY UNLEADED PETROL IN CONFORMITY WITH THE DIN 51607 STANDARD, MIN. 95 (N. O. R. M. ) AND 85 (N. O. M. M. ) AND HIGH PERFORMANCE SYNTHETIC OIL FOR 2 STROKE ENGINES. THE USE OF FUELS AND LUBRICANTS DIFFERENT FROM THOSE INDICATED CAUSES SEVERE FUNCTIONAL INCONVENIENCES TO THE VEHICLE AND THE VOIDING OF THE aprilia GUARANTEE. To have the catalytic converter functioning correctly for long periods and to reduce possible problems regarding the contamination of the thermal unit and of the exhaust, it is necessary to avoid covering long distances with the engine running at constantly low rpm. It is sufficient to alternate these periods with periods in which the engine runs at relatively high rpm, even if only for a few seconds, but rather frequently. [. . . ] 50) This operation should be carried out while the engine is warm so that the oil drains off faster. Once all the oil has drained off, replace the drain plug (3) and pour 820 cm3 of oil into the filler hole (2) (see LUBRICANT CHART). In case of oil leakages or malfunctions, contact your aprilia Official Dealer. DO NOT DISPOSE OF OIL IN THE ENVIRONMENT. 50 CLUTCH ADJUSTMENT (Fig. 51-52) This model is equipped with two devices for adjusting the length of the clutch cable. Check the correct adjustment of the clutch cable from time to time, ensuring that the idle stroke of the control lever is from 3 4 mm (Fig. If this distance is not correct, turn the control lever adjuster (1) or the adjuster on the motor cover (Fig. If it is not possible to adjust the clutch by means of the adjusters, contact your aprilia Official Dealer The clutch must be adjusted when it does not "release" correctly and the vehicle tends to move even with the clutch pulled. On the contrary, if the clutch slips the acceleration of the vehicle will not be in proportion to the acceleration of the motor. Fig. The vehicle has a separate lubrication system which includes an mixer oil tank (Fig. 53) (1, 3 l with a reserve of 0, 5 l ) and a variable-capacity oil supply pump (the capacity varies according to the number of revs of the motor and the opening of the throttle) (Fig. When the oil reaches reserve level, this is indicated by the coming on of the mixer oil reserve warning light " ". Fig. 53 The capacity is predetermined in the design phase, so there is no need for the user to make any adjustment. It is necessary to bleed air from the pump whenever it has to be dismantled, the mixer oil supply pipe is detached, or when the lubricant in the mixer oil tank is completely exhausted. Start the motor and let it idle. 52 Unscrew the drainage screw (1) and at the same time completely rotate the pump control lever (2) until the oil drains off, then tighten the screw again. Keep the pump lever rotated until all traces of air bubbles have completely disappeared from the carburettor supply pipe. For greater safety we advise using up all the blended fuel in the tank before refilling with only premium grade petrol (see "TECHNICAL FEATURES"). Adjust the motor idling speed, then check that the end play of the oil pump and the carburettor cables is the same; if not, regulate the adjusters provided in order to obtain a clearance of 1 mm. 54 53 Unscrew the pump control rod (4) and restore the clearance between the brake adjuster and the stroke point. Make sure that some clearance is present between brake rod and master cylinder. This will avoid brake to be left unintentionally operated with a consequent early wear of braking system parts. 4 3 1 Fig. 55 Brake rod and master cylinder clearance shall be: 0. 5 1 mm. 2 Lock the pump control rod by means of the lock nut (3). If necessary, contact your aprilia Official Dealer. ADJUSTING THE REAR BRAKE (Fig. 55) The brake pedal is positioned ergonomically during the assembly phase. If necessary, it is possible to adjust the height of the brake pedal: Screw the lock nut (3) on the pump control rod (4) completely. Screw or loosen adjuster (2) until the pedal is at the desired height.
