Understanding the design and function of the electrical charging system of your vintage Honda two-cylinder motorcycle is a key system to keeping your bike running reliably. The two-cylinder motorcycles produced by Honda from 1965 to 1977 all use a permanent magnet single phase charging system to keep the battery charged when the bike is running. While the stator and permanent magnet rotor are generally rock solid, it is important to know how to test them and verify your charging system is working.

fantastic videos. Wish these were around when I first started wrenching.
U r doing a gr8 service to old school bikez Many thanks
Great video. Thanks for doing and sharing!
Good information!!!
Thank you!
Good one.
At 12:13, you state if one or more of the magnets are weak, the rotor needs to be replaced. However, it appears the magnets are set in via press pins on the top. I think one can argue that a rotor can be remanufactured by removing these pins, replacing the magnets with fresh neodymiums, and then grind then down via machine lathe...like I'm sure Honda did originally. The labor in shaping the magnets would be the biggest cost, of course. But, it would save these rotors from being scrapped to the junkyard! Just my .02c.

I don’t think those watching this have access to a lathe, myself included, but I’m all for reusing parts
thank u excellant
1972 CL350 measured 38V AC between white and pink wires while running. 16V AC between yellow and pink wires. Ohm test checked out OK. 12V DC drops to 12.2V DC running and 12.4V DC with the key off. The battery is new, but a crappy lead acid one. Why did the AC voltage measure high?
Now my 360 runs good up until I turn the headlight on, then dies. Turn headlight off and fire right up. I get home and check the battery, and is fully charged. Would this be stator or rectifier?

I’m having the same issue on my cb125
Anyone know if this is applicable to the 1973-1974 Honda xl175 stator?
I have some questions, I'm in the middle of restoring my honda GL100, will the magnet stator affect the quality spark?

I know this is a bit late to respond to, but from my knowledge if the charging system is inoperative or too weak to keep the battery charged, it will affect spark at higher rpms
