User manual MALAGUTI PHANTOM F12R BROCHURE

[. . . ] Situations entailing the risk of personal injury to maintenance or repair mechanics, other workshop personnel or third parties, or damage to environment, vehicle or equipment. Indicates that negative pole is to be disconnected from the battery before performing the operation. Indicates operations which may constitute a risk of explosion. Indicates information which may be obtained by referring to said manual. [. . . ] Before any servicing, make sure that the motor-bike is perfectly stable. The front wheel should preferably be anchored to the equipment (A - F. Operations to be made, and the components and items subject to wear to be replaced. Spark plug Arcenr i lae Idle speed Transmission oil Bolts and nuts Fud li Coolant Egn ol nie i Remove the spark plug while the engine is hot (taking utmost care to avoid scalding!The carbon deposits and the colour of the insulator (around the central electrode) provide good information as to the carburetion, heat range of the spark plug and to carburetion lubrication and general condition of the engine. A light brown c l u o (the insulator) indicates that engine working conditions are generally correct oor f correct.

If need be, adjust by acting only on the earth electrode electrode. Clean the electrodes and the insulator thoroughly by means of a wire brush. Remove any residual dirt with a strong jet of compressed ar i. -Install the spark plug, screw it by hand and then tighten it with the spark plug wrench. The spark plug has to be removed when the engine is cold. The use of igniters or spark plugs which do not conform or differ from the recommended ones, can seriously damage the engine. 7) after removing the respective clamp; remove the tappet cover complete with decanter and automatic valve. -Be sure that the unidirectional valve works properly. TIMING INSPECTION -Remove the 4 fastening screws and take off from the engine the flywheel cover complete with water pump and cooling hoses. -Rotate the flywheel until the reference mark lies close to the (TDC), as shown in the picture . Be sure that the 4V reference mark made on the camshaft control pulley is aligned with the reference point on the head (F. If the reference mark is on the opposite side of the index made on the head, rotate the driving shaft again. -The TDC reference mark is repeated between the cooling fan and the cover of the flywheel. To use this reference mark, remove the spark plug and rotate the engine in the direction opposite to the normal rotation, by means of a compass wrench applied to the bell of the camshaft control pulley. [. . . ] Values higher than 12, 5% are considered as correct. Values which do not comply with are a sign of a lack of sealing on the exhaust system. -Unburnt hydrocarbons (HC) are measured in parts per million (PPM): the HC value decreases with the rpm increasing. With idle engine, it is normal to have values of 200 ÷ 400 PPM; this emission values have to be considered as normal for an engine with a motorcycle timing diagram. [. . . ]
