IGNITION SYSTEM CHECK
1. Remove the spark plug and re-
attach it to the spark plug lead.
2. Put the engine stop switch in the
“RUN” position and ignition switch
in the “ON” position. While holding
the spark plug base firmly against
the engine, push the starter but-
ton. If the ignition system is oper-
ating properly, a blue spark should
jump across the spark plug gap. If
there is no spark, take your
machine to your authorized
Suzuki dealer.
COMPLAINT:
Engine stalls
1. Make sure there is enough fuel in
the fuel tank.
2. Check to see that the spark plug
is not fouled. Remove the plug
and clean it. Replace it, if neces-
sary.
3. Make sure the fuel valve is not
clogged. Also check to be sure the
air vent hose connected to the fuel
tank is not clogged.
4. Check the idle speed. If neces-
sary, adjust it using a tachometer.
The correct idle speed is 1800 –
2000 r/min.
