Charging Rotors interchangeable?????

[HooliganCycles]

Can you put a rotor from an 81 onto a 77? I know they are different part numbers but didn't know if you could swap them I need one for my 77

yes. The 81 will have a magnet in it to trigger the TCI. You can put ANY rotor on a Non-TCI bike, or if you are already running Pamco/Boyer/Points then it doesn't matter.

But if you are running TCI, you cannot use a NON-TCI rotor on your bike and keep the oem electronic ignition

Awesome thanks Hugh. I'm gonna rob the rotor of my 81 and put it on my 77 for now and order your PMA for my 81, and when I have more money order another one for my 77. Thanks a lot!

Can you put a 80+ stator on a 75 Rotor?

 

[gggGary]

Yes, AFAIK all stators interchange. But the 80 up stators have mounting holes for the ignition pickup.

The later ones have the isolated brush for the later rec/reg, so that would have to be changed, too.

I also have a 77 and want to use 81 rotor. What do I use as timming marks to set the 77's?

 

[gggGary]

timing marks are the same. Not sure if an 81 stator would have the advance mark. Never hurts to confirm that TDC matches the rotor mark.

Edited after twins comment.

The rotor just has one mark on it, a "pointer" so to speak. The timing marks it points to are on the stator.
