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. [. . . ] If there are twist then replace the hose. Fig. 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 the pump control rod completely (4). Screw or loosen adjuster (2) until the pedal is at the desired height. Lock the brake adjuster (2) by means of the lock nut (1). 54 CHECKING AND BLEEDING THE FRONT AND REAR BRAKE (Fig. 56) The vehicle is provided with a hydraulically controlled front and rear disc brake. The brake fluid level in the pump tank must be checked from time to time. After the first 500 km or whenever an excessive idle stroke of the lever is found, the hydraulic system must be bled to remove any air bubbles that may have formed. The bleeding operations for the front and rear braking system are the same. Remove the protection cap of the caliper breather valve (1). Fit one end of a transparent PVC tube (2) over the end of the caliper breather valve. The other end of the tube must be placed in a receptacle to catch the fluid (3). Remove the lid of the brake fluid pump and check that the level is correct. If necessary, top up (see LUBRICANT CHART). Pull the brake lever slowly and completely (2-3 times). Keeping the lever in pulled position, open the breather valve (1) until fluid and any air bubbles can be seen coming out of the tube. Close the valve again and release the brake lever. Repeat the operation described above until no more air bubbles can be seen in the fluid coming out of the valve. Fig. [. . . ] LTD. RC PERFECT MOTORS COMPANY LIMITED KWT ZED MOTORZ - Div.
