You use the adaptor that fits on the 6V engines to fit a 12V flywheel on the 6V crank taper. The 12V stator will bolt right up to 6V engine cases if you modify the engine case for the pulse trigger on the stator plate. You can also use a 12V inner rotor kit, or pick one of the 6V CDI stators and still use the 6V flywheel, no adaptor needed with that, nor do you need to modify the engine case.

I have the pitster pro stator. It required I use this bushing. I read some stators don't require the use of a bushing (link below). Which are those?

I need 12v.

Links?

The adaptor is for the flywheel to seat properly on the smaller-tapered 6V crank end, it has nothing to do with the stator plate directly. The PitsterPro flywheel has a bigger taper than a 6V Honda flywheel from a '69-'87 Z50, the '69-'82 CT70, and all the other 6V Honda engines, and requires use of the adaptor on a 6V crank. You also need the adaptor if you use a 12V Inner rotor kit, but you do not need it if you use the 6V CDI stator sold HERE. That conversion uses the stock 6V flywheel that came with the engine.

Thank you for a detailed post. :) It's a 1972 CT70. So, if I want 12v, I am stuck with the bushing?

I have this at a buddies who is doing it for me. I went by there, after install, no spark to plug. We removed all wires and tested off stator and I tried to start it to see if we got juice, and nothing on all wires with volt meter. I assume, its a bad one. Is there better out there? Or return and get another?

Thanks for your quick replies.
 
Yes, if you want to use a 12v CDI-type ignition, you have to use the adaptor.

All things being equal, with the 12V stator plugged into a 12V CDI harness and 12V ignition coil properly grounded, you should have a good spark at the plug, grounding it to the engine while hand kicking.

Ya, we got nothing. :(

The reason for asking about bushing, is we notice, we only get 4-5 full turns on the nut for flywheel(?) when we put it on. Friend was concerned maybe not enough. Thought maybe if we could find one without needing a bushing.

So, safe to assume, no spark plugged into harness or nothing plugged in, its DOA. Need another?

Is there better out there? I heard the watts are low on these stators?
 
Double check to make sure the little tab on the outer edge of the flywheel passes directly over the center of the pulse pickup tab, to trip the pulse trigger.

As far as pronouncing it DOA, that's hard for me to say, there could be other reasons why it won't spark for you. Hard to diagnose when you don't have the bike in front of you, especially when it comes to electricals.

Is there better out there? That's hard to say, as well. I've never personally had a bad stator out of the box, or ever had one go bad on me.

Thank you for this great information. I am trying to upgrade my '73 Honda CT70 engine to 12v cdi, using the rotor and stator off of a chinese clone engine. I definitely need an adapter to make the rotor fit on the Honda crankshaft, and am having no luck finding one. The ebay seller in the above link appears to be inactive, so can anybody help me find the adapter, please?

If I have to get the whole kit, then I will, but I don't even see any that come with the adapter at this point.


Thank you in advance!

Geoff
