when installing a spark plug, a good

Engine oil

The engine oil level should be chec-
ked before each ride. In addition, the
oil must be changed at the intervals
specified in the periodic maintenance
and lubrication chart and when the oil
change indicator display comes on.
To check the engine oil level
1. Place the scooter on the centers-
tand. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
3. Wait a few minutes until the oil
settles, remove the oil filler cap,
wipe the dipstick clean, insert it
back into the oil filler hole (wit-
hout screwing it in), and then
remove it again to check the oil
level.
