CHAPTER 2.
PERIODIC INSPECTION AND ADJUSTMENT
2-1. INTRODUCTION
This chapter includes all information necessary to perform recommended inspection and adjustments, These
preventive maintenance procedures, if followed, will insure more reliable vehicle operation and a longer service
life. The need for costly overhaul work will be greatly reduced. This information applies not only to vehicles
already in service, but also to new vehicles that are being prepared for sale. Any service technician performing
preparation work should be familiar with this entire chapter.
2-2. MAINTENANCE INTERVALS CHARTS
The following charts should be considered strictly as a guide to general maintenance and lubrication intervals.
You must take into consideration that weather, terrain, geographical location, and a variety of individual uses
all tend to alter this time schedule. For example, if the motorcycle is continually operated in an area of high
humidity, then all parts must be lubricated much more frequently than shown
caused by water to metal parts,
on the chart to avoid damage

2-3. ENGINE
A. Carburetor
1. Idle mixture
The idle mixture is set at the factory by
the use of special equipment. No attempt
should be made to change this adjustment
by the dealer.
1. Do not adjust
Throttle
2.
Turn the throttle grip to see if it operates
properly and if the play is normal. Make
certain the throttle snaps closed when
released.
b. Install the attachment and set the vacuum
gauge.
c. Start motorcycle and allow it to warm up
for 2
-
3 minutes. The warm-up is complete when engine responds normally to
throttle opening.
d. Adjust damping valve on each vacuum
gauge until the needle flutters only
slightly. The gauge needles must respond
quickly to rapid opening of the throttle.
Both gauge will indicate the same reading
e.
if the carburetors are synchronized.
f.
Turn the synchronizing screw until the
gauge readings are the same.
1.
5 - 8 mm (0.2 - 0.3 in)
3. Synchronization
NOTE:
Ignition timing and valve clearances must
be set properly before synchronizing
carburetors.
Procedure:
a. Turn fuel
petcocks
to “PRIME”, and
remove the plug screws for the adapter
attachment holes in the carburetor body.
1. Synchronizing screw
After adjustment, firmly tighten the plug
g.
screws.
NOTE:
Check gasket. Replace if damaged.
4. Idle speed adjustment.
NOTE:
Carburetors must be synchronized before
setting final idle speed.
a. Start the engine and warm it up for a few
minutes.
b. Set the engine idle speed to specified rpm
by turning the throttle stop screw in to
increase the engine speed and back off the
screw to decrease the engine speed.
Use a tachometer for checking and adjusting the engine speed.
