Oil level measurement
1. Place the scooter on the center-
stand. Warm up the engine for
several minutes.
NOTE:
8 Be sure the scooter is positioned
straight up when checking the oil
level. A slight tilt toward the side
can result in false readings.
8 When adding oil, be careful not
to overfill the engine; the oil level
rises faster starting from the half
level portion on the dipstick.
