PERIODIC MAINTENANCE AND MINOR REPAIR

6-8

The ideal color on the white insula-
tor a round the center electrode is a
medium-to-light tan color for a
scooter that is being ridden nor-
mally.

Do not attempt to diagnose such
problems yourself. Instead, take the
scooter to a Yamaha dealer . You
should periodically remove and in-
spect the spark plug because heat
and deposits will cause any spark
plug to slowly break down and
erode. If electrode erosion becomes
excessive, or if carbon and other
deposits are excessive, you should
replace the spark plug.

Specified spark plug:

BPR7HS (NGK)

Installation

1. Measure the electrode gap with

a wire thickness gauge and, if
necessary, adjust the gap to
specification.

Spark plug gap:

0.9 ~ 1.0 mm

2. Clean the gasket surface. Wipe

off any grime from the threads.

3. Install the spark plug and tighten

it to the specified torque, then
replace the spark plug cap.

1.

Spark plug gap

1

Tightening torque:

Spark plug:

20 Nm (2.0 mkg)

NOTE:

If a torque wrench is not available
when you are installing a sprark
plug, a good estimate of the correct
torque is 1/4 to 1/2 turn past finger
tight. Have the spark plug tightened
to the specified torque as soon as
possible.

4. Install the panel.
