3.2 Cleaning and adjusting spark plug
You should periodically remove and inspect the spark plug because heat and deposits will cause the spark
plug to slowly break down and erode. If necessary, you should replace the spark plug with another of the
correct type.
Before fitting the spark plug, measure the electrode gap with a wire thickness gauge; adjust the gap to
specification if necessary.
When fitting the plug, always clean the gasket surface and use a new gasket. Wipe off any dirt from the
threads and screw in the spark plug to the correct torque.
3.3 Checking the fuel system
1. Check the fuel lines for leaks, crack, or malfunction. If a problem is found, your dealer or other qualified
mechanic should repair it immediately.
