STARTING THE ENGINE
Always follow the proper starting procedure
described below.
Y our motorcycle's exhaust contains
poisonous carbon monoxide gas. High
levels of carbon monoxide can collect
rapidly in enclosed areas such as a garage.
Do not run the engine with the garage door
closed. Even with the door open, run the
engine only long enough to move your
motorcycle out of the garage.
To protect the catalytic converter in your
motorcycle's exhaust system, avoid
extending idling and the use of leaded
petrol.

Do not use the electric starter for more than
5 seconds at a time. Release the start button
for approximately 10 seconds before
pressing it again.
