TROUBLESHOOTING
There can be various causes for problems which might
occur on the motorcycle. The following procedures may be
used to troubleshoot possible trouble spots.
ENGINE WILL NOT START
FUEL SYSTEM
1. Check that the there is sufficient gasoline in the fuel
tank.
2. Make sure the fuelcock lever and fuel tank breather hose
are not clogged,
SPARK PLUG
1. Check that the spark plug gap has not been bridged and
short circuited by carbon.
2. Check that the plug is not fouled with wet gasoline or oil.
3. Clean the spark plug gap and lay the connected spark
plug against the cylinder head. Kick over the engine and
see if a spark is produced, If not, replace the spark plug
of check your ignition system.
4. To check the ignition system, remove the spark plug cap
from the high tension wire and hold it about 7 mm (0.28
in.) from the cylinder head (ground). Kick the engine
over and soe if a spark jumps this gap. If so, the system
is functioning and the problem is probably in the spark
plug cap. If this does not produce a spark, have your
SUZUKI dealer check your ignition system,
