However, the idling speed may be performed
by the owner as a part of the usual mainte-
nance routine.
Idle speed adjustment
1. Start the engine and warm it up for a few
minutes at nearly 1,000 to 2,000 r/min. Some-
times rev the engine to 4,000 to 5,000 r/min.
The engine is earm when it quickly responds
to the throttle.
2. Connect the tachometer and set the idle to
the specified idling speed by adjusting the
throttle stop screw. Turn the screw in to in-
crease engine speed, and out to decrease
engine speed.
Valve clearance adjustment
The proper valve clearance changes with use,
leading to incorrect fuel/air supply or engine
noise. To prevent this, the valve clearance
must be adjusted periodically. This adjust-
ment however, should be left to a professional
service technician.
Cam chain adjustment
The cam chain will loosen with use, resulting
in improper valve timing and engine noise.
To prevent this, the cam chain tensioner must
be adjusted regularly. This adjustment should
be left to your dealer.
