4-2 NOTE:
Pre-operation checks should be made each time the motorcycle is used. Such an inspection can be thoroughly accomplished
in a very short time; and the added safety it assures is more than worth the time involved. If any maintenance service or
adjustment is needed, consult the chart above to refer to the pages in which the service or adjustment is described.
1. The engine, exhaust pipe, and muffler will be very hot after the engine has been run.
Be careful not to touch them or to allow any clothing item to contact them during inspection or repair.
2. If any item is not working properly, have it inspected and repaired before operating the motorcycle.
