Periodic Maintenance
34 Servicing Your Honda
In addition to the regularly scheduled maintenance (page 35) and daily pre-ride inspection
(page 19),
consider performing the periodic checks on the following page at least once a month,
even if you haven’t ridden your motorcycle, or as often as once a week if you ride frequently
or for long distances. It’s a good idea to perform this maintenance any time you clean your
motorcycle.
Check the odometer reading and perform any scheduled maintenance checks that are needed
(page 35). Remember, more frequent checks may be needed for riding in severe conditions.
Tires & Wheels Check the air pressure with a gauge and add air if needed
(page 127).
Examine the tread for wear (page 127).
Look closely for nails, embedded objects, cuts, and other types of
damage (page 127). Roll your motorcycle so you can inspect the
entire surface.
Check the condition of the rims and spokes.
Fluids Check the levels of the engine oil (page 70), coolant (page 72) and
brake fluid (page 123). Add the correct fluid as necessary, and
investigate the cause of any low fluid level.
Lights Make sure the headlight, position lights, brake light, taillight, and turn
signals are working properly.
Freeplay Check the freeplay of the clutch lever (page 81) and throttle grip
(page 79).
Drive Chain Check condition, adjust slack, and lubricate as needed (page 130).
Fuses Make sure you have a full supply of spare fuses.
Nuts & Bolts Check the major fasteners and tighten as needed.
