A diagnostic tachometer must be used for this pro-
cedure.

1. Start the engine and warm it up for a few min-
utes at approximately 1,000 to 2,000 r/min.
Occasionally rev the engine to 4,000 to 5,000
r/min. The engine is warm when it quickly re-
sponds to the throttle.
2. Remove the seats. (See page 4-43 for seat
removal and installation procedures.)
3. Remove the console. (See page 8-21 for
console removal and installation proce-
dures.)
4. Connect the tachometer to the spark plug
lead, and then set the idle to the specified
idling speed by adjusting the throttle stop
screw. Turn the screw in direction a to in-
crease the engine speed, and in direction b
to decrease the engine speed.
Specified idle speed:
1,450–1,550 r/min
