User manual APRILIA MX 125

[. . . ] The catalytic version of the MX50 is fitted with a silencer with metal catalytic converter of the "platinum-rhodium bivalent" type. This device provides for the oxidation of the CO (carbon monoxide) and of the HC (unburned hydrocarbons) contained in the exhaust gases, changing them into carbon dioxide and steam, respectively. Due to the catalytic reaction, the high temperature reached by the exhaust gases results in the burning of the oil particles, thus keeping the silencer clean and eliminating the exhaust fumes. Avoid parking the catalytic vehicle near dry brush wood or in places easily accessible to children, as the catalytic silencer becomes extremely hot during use; be very careful and avoid any kind of contact before it has completely cooled down. [. . . ] 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. 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 ÷ 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. The vehicle has a separate lubrication system which includes an mixer oil tank (Fig. 13) (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). When the oil reaches reserve level, this is indicated by the coming on of the mixer oil reserve warning light "". 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. Proceed as follows: Empty the fuel tank and fill it with 2 ÷ 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. Never fit a new drive chain on a sprocket wheel/ crown gear with very worn teeth; vice versa do not use a worn chain on a new sprocket wheel/crown gear. Every 4000 km, or according to conditions of use, clean the filtering element as follows: Unscrew and remove the saddle locking nut positioned under the mudguard. Wash the filtering element with clean, not-inflammable solvents or solvents with high volatility point, then let it dry thoroughly. Apply a filter oil or a thick oil (SAE 80W-90) on the whole surface of the filtering element, then squeeze it to eliminate the oil in excess. The filter must be well impregnated, though not dripping Reassemble performing all the operations in reverse order, being careful to close the filter box cover correctly. Do not use the vehicle if the coolant is below the minimum allowed level. Do not remove the radiator plug when the engine is hot, since the coolant is under pressure and its temperature is high. If it gets in contact with the skin or with clothes it can cause severe burns and/or damages. Every 2000 km or after using the vehicle in difficult conditions, check the coolant level with cold engine; change the coolant every two years. The coolant level must be included between 1/4th and 3/4ths of the expansion tank capacity (Fig. The standard coolant makes it possible to expose the vehicle to temperatures down to -17°C. [. . . ] Proceed as follows: Unscrew the two screws (1); Remove the glass (2); Press the bulb slightly and rotate it anticlockwise; Remove the bulb from its seat. The introduction of a new bulb can be carried out in one sense only, since the two guide pins are misaligned. Install a new bulb correctly, then repeat the above operations in the reverse order for the reassembly. We advise cleaning the vehicle frequently, not only for the sake of its appearance, but also because cleanliness helps to keep your vehicle in good condition and prolongs the life of its various parts.
