User manual MOTO GUZZI V 11 SPORT

[. . . ] The contents of this Manual is not binding and Moto Guzzi reserves the right to make alterations, if and when required, of components, accessories, tooling, etc. Which are deemed expendient for the purpose of improvement or, for any technical - commercial requirement, or in order to comply with law provision in the different countries, without however undertaking to promptly up-date this Manual. The purpose of this manual is to provide instructions for carrying out overhauls and repair work correctly. The following data aim at providing an overview of the main tests to be carried out when overhauling the various units. [. . . ] The electric pump "1" sucks in fuel from the tank "S" and delivers it "2" to the electro-injectors "3" by means of a filter. The fuel pressure in the circuit is kept stable by the pressure adjustor "4". WARNING In some vehicles the position of the pump and the fuel filter can be inverted. Flames, cigarettes and other objects emitting heat, if present during tank removal procedures or in places where fuel is stored, are a great risk for the operator. Remove the saddle as described in section E, chapter 4; Unscrew and remove the fastening screw "A"; Remove the washer "B"; On the RH side detach: Loosen the clamp "C" and remove the tube from the pressure adjuster "D"; On the LH side detach: The connection for the fuel level sensor "E" and the connection for the fuel solenoid valve "F"; Loosen the clamp "G" and remove the tube from the fuel solenoid valve "H"; Lift the rear part of the tank and remove it by sliding it backwards. Reassembly: When refitting, insert the front part of the tank into the chassis and fasten it using the special screw in the rear part; re-attach all the previously detached connections; refit the saddle. The motorbike is equipped with a volumetric roller type electrical pump whose motor is immersed in the fuel. When the impeller rotates, driven by the motor, it generates volumes which move from the intake gate to the delivery gate. These volumes are delimited by rollers which adhere to the external ring while the motor is rotating. The pump is fitted with a check valve which is necessary in order to prevent the fuel circuit from emptying when the pump is not working. It is also equipped with an pressure valve, which shortcircuits the delivery with the intake when the pressure exceeds ~5 bar, thereby preventing the electrical motor from overheating. Always make sure the system is clean when disassembling and assembling the piping and the components. Remove the tank as described in chapter 3 in this section; Disconnect the two connections "A" and "B" from the pump, taking note of their position for subsequent reassembly; Remove the fuel inlet pipe "C" from the pump by loosening the respective clamp; Remove the fuel outlet pipe "D" from the pump by loosening the respective clamp; Unscrew and remove the two nuts "E"; Remove the pump "F" from the chassis. In some motorbikes the position of the filter and the fuel pump can be inverted. The filter is equipped with a paper filtering element, with a surface area of about 1200 cm2, and a filtering capacity of 10 µm: these features are essential, given the injectors' high sensitivity to foreign bodies. The filter is fitted under the fuel pump between the pump and the throttle body units and has an arrow on its external casing which indicates the fuel flow direction. It is an "all or nothing" device, in that it only has two modes: open or closed. The injector is composed of a body and a jet needle which is integral to the magnetic armature. The jet needle is pressed onto the restraining seat by means of a helical spring whose load is determined by an adjustable thrust spring. The injector snug is machined in the front part (retaining seat and guide for the needle). The control pulses established by the ECU create a magnetic field which attracts the armature and causes the injector's opening. This time is determined by the control ECU according to the engine's conditions of use. [. . . ] WARNING The starter motor must not be activated for over 5 seconds; if the engine does not start, wait about 10 seconds before carrying out a subsequent ignition. The start button (START " " must only be used ) when the engine is off. Unscrew the two screws "A" and remove them together with the two washers; · Unscrew the screw "C" located at the bottom of the optic unit; · When replacing the front light bulb (high beamlow beam) take care not to touch the bulb directly with your fingers. Unscrew the 2 nuts "A" with washer; · Slowly and carefully slide out the tailight together with the grommet, the washer and the shim so as not to damage the electrical connections; · Detach the three connectors " and remove the B" rear tailight from the motorbike.
