HOW TO USE THIS MANUAL
This manual is intended as a handy, easy-to-read reference book for the mechanic. Comprehensive
explanations of all installation, removal, disassembly, assembly, repair and check procedures are laid
out with the individual steps in sequential order.
1
The manual is divided into chapters. An abbreviation and symbol in the upper right corner of each
page indicate the current chapter.
Refer to “SYMBOLS”.
2
Each chapter is divided into sections. The current section title is shown at the top of each page,
except in Chapter 3 (“PERIODIC CHECKS AND ADJUSTMENTS”), where the sub-section title(s) appears.
3
Sub-section titles appear in smaller print than the section title.
4
To help identify parts and clarify procedure steps, there are exploded diagrams at the start of each
removal and disassembly section.
5
Numbers are given in the order of the jobs in the exploded diagram. A circled number indicates a
disassembly step.
6
Symbols indicate parts to be lubricated or replaced.
Refer to “SYMBOLS”.
7
A job instruction chart accompanies the exploded diagram, providing the order of jobs, names of
parts, notes in jobs, etc.
8
Jobs requiring more information (such as special tools and technical data) are described sequentially.

If the engine stop switch is set to “
main switch is set to “ON” (both switches are
closed), the starter motor can only operate if at
least one of the following conditions is met:
S The transmission is in neutral (the neutral
switch is closed).
S The clutch lever is pulled to the handlebar
(the clutch switch is closed) and the sidestand is up (the sidestand switch is closed).
The starting circuit cut-off relay prevents the
starter motor from operating when neither of
these conditions has been met. In this instance,
the starting circuit cut-off relay is open so current cannot reach the starter motor. When at
least one of the above conditions has been met
the starting circuit cut-off relay is closed and the
engine can be started by pressing the starter
switch.
