The starter motor runs when the transmission is in neutral, but does not run when the transmission is in any position
other than neutral, with the side-stand up.
Step Action Yes No
1 1) Shift the transmission into neutral.
2) Grasp the clutch lever, turn on the ignition switch with

pushed.
Is a click sound heard?
Go to step 2. Go to step 3.
2 Check if the starter motor runs when its terminal is
connected to the battery (+) terminal. (Do not use thin “wire”
because a large amount of current flows.)
