ADJUSTING THE DRIVE BELT SLACK
TIP
The drive belt slack must be checked at the
tightest point on the belt.
ECA14950
A drive belt that is too tight will overload
the engine and other vital parts, and one
that is too loose can skip and damage the
swingarm or cause an accident. Therefore,
keep the drive belt slack within the speci-
fied limits.
TIP
Measure the drive belt slack when the engine
is cold, and when the drive belt is dry.
1. Stand the vehicle on a level surface.
EWA13120
WARNING
Securely support the vehicle so that there
is no danger of it falling over.
PERIODIC MAINTENANCE
TIP
Place the vehicle on the sidestand or on a suit-
able stand so that the rear wheel is elevated.
2. Check:
• Drive belt slack "a"
Out of specification → Adjust.
Drive belt slack (on the side-
stand)
3.0–5.0 mm (0.12–0.20 in)
Drive belt slack (on a suitable
stand)
3.0–5.0 mm (0.12–0.20 in)
TIP
• The level marks "1" of the level window on
the lower drive belt cover are in units of 5 mm
(0.20 in). Use them as a standard for mea-
suring the drive belt slack.
• Measure the drive belt slack when the drive
belt has been pushed with 45 N (4.5 kgf, 10
lbf) of pressure using a belt tension gauge
"2".
