Ignition System Check
1. Remove the spark plugs and reat-
tach them to the spark plug leads.
2. Put the engine stop switch in the
"(" position and ignition switch in
the "ON" position. While holding the
spark plug with its base firmly
against the engine, push the elec-
tric starter button. If the ignition sys-
tem is operating properly, a blue
spark should jump across the spark
plug gap. If there is no spark, take
your machine to your authorized
Suzuki dealer
mechanic.
