Starter (choke) knob
Starting a cold engine requires a richer
air-fuel mixture, which is supplied by
the starter (choke).
Move the knob in direction (a) to turn
on the starter (choke).
Move the knob in direction (b) to turn
off the starter (choke).

Kickstarter
To start the engine, fold out the kick-
starter lever, move it down lightly with
your foot until the gears engage, and
then push it down smoothly but force-
fully. This model is equipped with a pri-
mary kickstarter, allowing the engine to
be started in any gear if the clutch is
disengaged. However, shifting the
transmission into the neutral position
before starting is recommended.

Seat
To remove the seat
1. Pull up the rear of the seat and re- move the bolt.
2. Pull the seat upwards and rear- ward to remove it.
To install the seat 1. Fit the slot on the front of the seat onto the projection on the fuel
tank while inserting the projection
on the middle of the seat into the
seat holder. 2. Make sure the seat is in its original
position.
3. Install the bolt at the rear of the seat.
TIP
When removing and installing the
seat, be careful not to damage the
seat with a tool.
Make sure that the seat is properly
secured before riding.

Install the protector so that the side
with the notch is facing rearward.

1. Remove the rubber cap by pulling it out of the front fork leg.
2. To increase the compression damping force and thereby hard-

Front fork blee din g
When riding in extremely rough condi-
tions, the air temperature and pressure
in the front fork will rise. This will in-
crease the spring preload and harden
the front suspension. If this occurs,
bleed the air from each front fork leg.
WARNING
EWA10201
Always blee d b oth fork le gs, other-
wise poor han dlin g an d loss of sta-

To bleed the front fork legs
1. Remove the protector.
2. Place the motorcycle on a suitable
stand. (See page 7-27.)
3. Make sure the front wheel is off the ground and the area near the
bleed screws is clean.
4. Remove the bleed screws.

make this adjustment.
The spring preload setting is
determined by measuring
distance A, shown in the illus-
