    Notes before Maintenance Please read the following precautions before checking, disassembling or assembling motorcycles. In order to facilitate the actual operation, the chapters are provided with notes, illustrations, pictures, precautions and detailed descriptions. This section describes the special precautions during the removal and reassembly or disassembly and reassembly of common parts.
  • Page 18: Cleaning Motorcycle Before Disassembly

    Cleaning Motorcycle before Disassembly Thoroughly clean the motorcycle before disassembly. If dust or other foreign materials enter the sealing area in the disassembly process, the excessive wear will be caused and the performance of motorcycles will be reduced. Collecting and Cleaning Removed Part The removed parts are easily confused.
  • Page 19: Replacement Part

    Replacement Part The replacement part must be an genuine part of Benelli or a part recommended by Benelli. Gaskets, O-ring seals, oil seals, grease seals, circlips or cotter pins and other parts must be replaced with new parts once they are removed.
  • Page 20: Force

    Force The common sense and basic ability of judgement must be owned in the part removal and installation process to prevent excessive force from resulting in maintenance difficulties or high maintenance cost. If necessary, remove the screws with non-permanent locking agent by using a pneumatic wrench. If it is needed to beat the fastener, a rubber hammer must be used.
  • Page 21: Ball Bearing And Needle Bearing

    Ball Bearing and Needle Bearing If not necessary, do not remove the ball or needle in the bearing. Once the ball or needle is removed, it must be replaced with a new one. When pressing the bearing, note that the manufacturer and size signs shall be placed outward.
  • Page 22: Circlip And Cotter Pin

    Circlip and Cotter Pin Replace the removed circlip or cotter pin with a new one. In order to prevent deformation, the opening of circlip or cotter pin cannot be too large during installation. Lubrication In order to minimize the abrasion during running-in, the lubricant must be applied to the rotating parts or sliding parts.
  • Page 23: Wire

    Wire Dual-color wire: the first is the base color, then the color of stripe. Unless noted otherwise, only the wires with the same color can be connected. Cable Connector Check Make sure that there are no corrosion, moisture and other foreign materials on the connector.

    Introduction to EFI This motorcycle adopts the small engine EFI (electronic fuel injection) system of Delphi Corporation. This system achieves closed-loop control, fuel injection and ignition control through oxygen sensor. Three-way catalytic converter is used to treat the gas after the combustion of engine, to convert it into harmless gas and discharge it to the atmosphere. This system uses closed-loop control self-learning system, which can effectively eliminate the manufacturing differences of system and related mechanical parts, improve the overall consistency of the motorcycle, and eliminate the error of motorcycle caused due to wear and other causes after actual use.
