Can anyone tell me the difference in stator parts for the two different flywheels on a 1971 CT70H? Thanks

I dunno exactly what you mean. There aren't any specs, other than impedence values and those are the same for all 6v stators.

Suffice it to say that no Hitachi parts interchange with Mitsubishi.

I have always wondered too. I'd like to see them side by side. I do have a S65,CTH and a CT but I hate to take them apart :D

I think every single thing is different except for the points.
Mitsubishi parts, OR, Hitachi parts. It's one or the other, nothing interchanges except points.

I have a lot of used parts. allenp42 is really good at repairing them, and he may have parts too. What exactly do you need?? What exactly do you have right now.

I have one of each and will post some pics in the next few days. X2 on previous posts; other than points, o-rings for the stator plate, mounting screws, nothing is the same or interchangeable. Even the mounting mounting holes for primary and lighting coils are not the same as a Hitachi. By this, I mean you can't even mount Hitachi coils on a Mitsu stator plate and vice versa. The ID of the Hitachi Flywheel is 84.75mm vs, 82mm for the Mitsubishi.

However, both work just fine when paired with their respective flywheel.

To throw another wrench in the works an S65 setup will work on an H too I believe but they are Denso. I'll have to dig one out

I have parts just got to figure out which parts are bad. Had bike running and just lost spark. What’s best way to check stator parts? Thanks

The biggest hurdle is the flywheel ID and how that impacts the coil armatures, including positioning, relative the stator plats, to fit the flywheel.

There are a few interesting tradeoffs. The Mitsubishi advance assembly is better built and easier to clean/restore. One saving grace is the fact that the coils can be rewound, if the windings are seriously damaged. The lighting coil is relatively easy, once you have the proper gauge of wire; there's some latitude, so you only need to get fairly close with the total amount of wire. Breaks requiring removal of only a short length of wire, near the end of a pigtail can simply be clipped, back to reach unbroken wire. Rewinding a primary ignition coil could be trickier; thus far, I know of no one who's attempted this. These alternators are pretty simple, about as basic as it gets...so there's a very good chance that it would be sufficiently DIY-friendly to be possible. And, there's always Ricky Stator; they may be able to take care of the rewinding chores for you. There's also converting to CDI...
