NOTE:
NOTE:
CAUTION:
8. Install:

spark plugs

ignition coils
Before installing the spark plug, clean the spark
plug and gasket surface.
9. Install:

radiator upper bolts

radiator lower bolt
Refer to “RADIATOR” in chapter 6.
10. Install:

side cowlings

bottom cowlings
Refer to “COWLINGS”.

MEASURING THE COMPRESSION
PRESSURE
The following procedure applies to all of the cyl-
inders.
Insufficient compression pressure will result in a
loss of performance.
1. Measure:

valve clearance
Out of specification
Adjust.
Refer to “ADJUSTING THE VALVE CLEAR-
ANCE”.
2. Start the engine, warm it up for several min-
utes, and then turn it off.
3. Remove:

ignition coils

spark plugs
Before removing the spark plugs, use com-
pressed air to blow away any dirt accumu-
lated in the spark plug wells to prevent it
from falling into the cylinders.
