Engine Oil & Filter
Install a New Engine Oil Filter:
Place shop towels under the oil filter cover because oil will flow out.
1. Remove the seat (page 122) and tank cover assembly (page 124).
2. Remove the oil filter cover (3) and O-rings (4) by removing the
bolts (5). Let the remaining oil drain out. Discard the oil filter (6)
in an approved manner (page 208).
3. Apply engine oil to new O-rings and install them to the oil filter
cover and crankcase cover.
4. Reposition the spring (7) to the crankcase cover and install a new
oil filter with the rubber seal (8) facing out, away from the
engine. You will see the "OUT-SIDE (TOWARDS FILTER COVER)"
mark (9) on the filter body, near the seal. Use only the Honda
Genuine oil filter or a filter of equivalent quality specified for your
model. Using the wrong Honda filter or a non-Honda filter which
is not of equivalent quality may cause engine damage.
NOTICE
Improper installation of the oil filter can cause serious engine
damage.
