STARTING AND OPERATION
STARTING AND OPERATION
CAUTION:
Prior to operating the machine, perform
steps listed in pre-operation check list.
WARNING
Never start your engine or let it run for any
length of time in a closed area. The exhaust
fumes are poisonous and can cause loss of
consciousness and death within a short
time. Always operate your machine in an
area with adequate ventilation.
STARTING A COLD ENGINE
WARNING
Before starting the engine, be sure to shift
the transmission into neutral.
NOTE:
 This model is equipped with an ignition cir-
cuit cut-off system. In case of electric start-
ing, the engine can be started only when the
transmission is in neutral.
 If the engine fails to start by pushing the start
switch, release the switch, wait a few sec-
onds, and then try again. Each starting
attempt should be as short as possible to
preserve the battery. Do not crank the
engine more than 10 seconds on any one
attempt.
1. Turn the fuel cock to “ON ”.
2. Turn the main switch to “ON ”.
3. Shift the transmission into neutral.
4. Operate the starter (choke) and completely close the throttle grip.
5. Slide the “engine stop ” switch to the “”.
6. Start the engine by pushing the start switch.
7. After the engine starts, warm up for one or
two minutes. Make sure the stater (choke) is
returned to the original position before riding. STARTING A WARM ENGINE
To start a warm engine, refer to the
“START-
ING A COLD ENGINE ” section. The starter
(choke) should not be used. The throttle
should be opened slightly.
CAUTION:
See “Engine break-in Section ” prior to
operating engine for the first time.
WARMING UP
To get maximum engine life, always “warm-up ”
the engine before starting off. Never accelerate
hard with a cold engine! To see whether or not
the engine is warm, see if it responds to throttle
normally with the stater (choke) turned off.
WARNING
Before starting off, be sure to turn up or
remove the side stand.
Failure to retract the side stand completely
can result in a serious accident when you
try to turn a corner.
ENGINE BREAK-IN
Break-in is important to better fit the moving
and sliding parts as well as the installed parts.
It is also important to accustom the rider to the
machine better.
Avoid full-throttle run on a new machine for the
first 5 hours.
After the trial run, check for loose parts, oil
leakage and other problems.
Make full inspection and adjustment especially of
slack cables and drive chain and loose spokes.
CAUTION:
After the break-in period, check every fit-
ting and fastener for looseness.
If any loose is found, retighten it securely.

crankcase.
(Except for USA and CDN)
CAUTION:
 Do not add any chemical additives or use
oils with a grade of CD a or higher.
 Do not use oils labeled “ENERGY CON-
SERVING II ” b or higher. Engine oil also
lubricates the clutch and additives could
cause clutch slippage.
 Do not allow foreign materials to enter the
crankcase.
