The upper valve is an original Trac 14×1 side mount, made in Korea.
All their inner seal disks have decomposed.
But there is a replacement inner seal disk D2 for $8 see below.

The lower one is a modern Honda substitute, made in China. It is a 14×1 vertical mount spigot left mounted sideways. The cover panel must be removed, or a large hole cut, to allow access to the substitute valve. There is no reserve capacity on the substitute, since the reserve tube is horizontal.

Many of the original valves had poorly made cast nuts. The nuts were too big and also weak. When fully tightened they would strip. Some have good nuts, but after 35 years the rubber seal disk inside is brittle and deformed. All of the mopeds listed that came with a spigot-back gas valve, can take a less expensive spigot down or spigot left valve.

The A28a valve has a 7.7 mm spigot, for 1/4″ (6.3mm) fuel hose.

Honda Design: Note that the little arrow on the handle points opposite to the handle. So off is arrow left (handle right), on is arrow up (handle down), reserve is arrow down (handle up).

Honda Design: Note that the little arrow on the handle points opposite to the handle. So off is arrow left (handle right), on is arrow up (handle down), reserve is arrow down (handle up).
