The "Periodic Maintenance / Lubrication Intervals" schedule is taken directly from a 1987 edition Honda SA50/50P and Elite 50LX/SR Factory Service Manual, which covers the '88-'93 Models (other models should be similar). Before starting any work, always consult the manual for your scooter's model and year, and be sure you know what you're doing.
