TIP
Engine air filter and V-belt air filters
• This model’s engine air filter is equipped with a disposable oil-coated paper element, which must not be cleaned
with compressed air to avoid damaging it.
• The engine air filter element needs to be replaced and the V-belt air filter elements need to be serviced more fre-
quently when riding in unusually wet or dusty areas.
Hydraulic brake service
• After disassembling the brake master cylinders and calipers, always change the fluid. Regularly check the brake
fluid levels and fill the reservoirs as required.
• Every two years replace the internal components of the brake master cylinders and calipers, and change the bra-
ke fluid.
• Replace the brake hoses every four years and if cracked or damaged.

damage and replace it if neces-
sary.
4. Install the air filter element with
the colored side facing outward.
NOTICE: Make sure that each
filter element is properly sea-
ted in its case. The engine
should never be operated wit-
hout the filter elements insta-
lled, otherwise the piston(s)
and/or cylinder(s) may become
excessively worn.

Adjusting the throttle cable
free play
1. Throttle cable free play
The throttle cable free play should
measure 3.0–5.0 mm (0.12–0.20 in) at
the inner edge of the throttle grip.
Periodically check the throttle cable
free play and, if necessary, adjust it as
follows.
TIP
The engine idling speed must be
correctly adjusted before checking
and adjusting the throttle cable free
play.
1. Slide the rubber cover back.
2. Loosen the locknut.3. To increase the throttle cable free
play, turn the adjusting nut in
direction (a). To decrease the
throttle cable free play, turn the
adjusting nut in direction (b).
1. Rubber protector
2. Locknut
3. Adjusting nut
4. Tighten the locknut and then sli-
de the rubber cover to its original
position.
