EAU44895

Ignition circuit cut-off system

This system prevents in-gear engine
starts unless the clutch lever is pulled
and the sidestand is up. Also, it will
stop the running engine should the
sidestand be lowered while the trans-
mission is in gear.
Periodically check the system via the
following procedure.

TIP



This check is most reliable if per-
formed with a warmed-up engine.



See pages 4-2 and 4-11 for switch
operation information.
