ENGINE OVERHAULING Cleaning of components All component must be cleaned with petrol and dried with compressed air. During this operation inflammable vapours burst out and metal particles may be violently ejected. Consequently, it is recommended to work in a room free from bare flames or sparks and that the operator wears goggles. Assemblies For a good and efficient engine operation, it is essential that all assemblies are within the tolerances prescribed.
Page 123: Recutting The Valve Seats
ENGINE OVERHAULING Recutting the valve seats Clean carbon and deposits from the valves. Apply some “Prussian blue” to the valve face and lap it against the seat with a suitable lapping tool. Remove the valve and measure the width “X” of the contact surface. If the width exceeds 0.06 in.
Page 124 ENGINE OVERHAULING Check the valve seat, if there are any low spots or other damage, the seat must be recut. It is important that the contact surface on the valve is in the right place on the valve. Use marking colour to determine where is the contact surface. The contact surface should be 0.02 in.

Page 289: Electronic Ignition System (Tc-Txc)
ELECTRIC SYSTEM, DIGITAL INSTRUMENT ELECTRONIC IGNITION SYSTEM (TC-TXC) In the C.D.I. system the electrical energy generated by the alternator charges the condenser. The energy is released in a single surge at the specified ignition timing and the current flows through the primary side of the ignition coil. A high voltage is induced in the secondary windings of the ignition coil, resulting a strong spark between the ignition spark plug gap.
Page 290: Electronic Ignition System (Te-Smr)
ELECTRIC SYSTEM, DIGITAL INSTRUMENT ELECTRONIC IGNITION SYSTEM (TE-SMR) The ignition system is controlled by the ECU (1). The system belongs to the category of the integrated systems of digital electronic ignition with advance and static distribution and gasoline electronic injection of intermittent sequential balanced type. This ignition system consists of a sensor of the crankshaft position (Pick-up), an ECU, an ignition coil and an air pressure sensor of the intake manifold.

Page 380 FUEL INJECTION SYSTEM FUEL INJECTION SYSTEM The fuel injection system consists of: fuel tank (1), electric pump (2), hose (3) and injector (4). The fuel in the tank is pumped by the fuel pump and the pressurized fuel flows into the injector installed in the throttle body (6). The fuel is injected into the throttle body with a conical dispersion when the injector opens according to the injection signal coming from the Electronic power unit (5) located under the fuel tank.
Page 381 FUEL INJECTION SYSTEM Operating instructions for the "DIAGNOSIS SOFTWARE KIT" on the fuel injection system Premised that the fuel injection system doesn’t need any programmed maintenance, the Diagnosis Software Kit code no. 8000 A9634 allows to effect the check of the components of the fuel injection system in case of malfunction. In case of malfunction on the right side of the instrument display will be dis- played the warning message “FAIL”, with the ignition key in ON position and the right commutator in RUN position.
Page 382 FUEL INJECTION SYSTEM This diagnosis software allows, besides the identification of the malfunctions in progress, also the memorization of those that are already occurred and that have been eliminated: for these last ones it is possible to effect the cancellation, following the instructions of the Operation Manual (page 29).
