The "Periodic Maintenance / Lubrication Intervals" schedule is taken directly from a 1986 edition Honda CH150 Factory Service Manual, and the 1984 edition Honda CH125 Factory Service Manual.  Before starting any work, always consult the manual for your scooter's model & year and be sure you know what you're doing.
