A. Spark plug gapSpark plug inspectionThe spark plug is an important engine
component and is easy to inspect.
The condition of the spark plug can
indicate the condition of the engine.
The ideal color on the white insulator
around the center electrode is a
medium-to-light tan color for a
Motorcycle that is being riddennormally. Do not attempt to diagnose
any problems yourself. Instead, take
the Motorcycle to a YAMAHA dealer.
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
electrode erosion becomes exces-
sive, or if carbon and other deposits
are excessive, you should replace the
spark plug with the specified plug.
Before installing the spark plug,
measure the electrode gap with a wire
thickness gauge; adjust the gap to
specification as necessary.
PERIODIC MAINTENANCE AND MINOR REPAIR

A.- Spark plug gap: 0.8 ±0.1 mm
When installing the plug, always
clean the gasket surface and use a
new gasket. Wipe off any grime from
the threads and tighten the spark plug
to the specified torque.
Tightening torque:
Spark plug:
12 ft-lb (1.75 m-kg)NOTE :If a torque wrench is not available
when you are installing a spark plug,
a good estimate of the correct
torque is 1/4 to 1/2 turn past finger
using a box spanner.
AALWAYS USE ONLY THE STANDARD RECOMMENDED MAKE AND TYPE OF
SPARK PLUG
Specified spark plug:
