Does anyone have experience with Boyer rotors losing magnetism?

Also, does anyone know where I can purchase just the rotor (Boyer pn# ROT00118) ?
 
I installed an old boyer in a 750. It was kicking back trying to start it and took several kicks to get it going. After swapping out the black box and then the stator with no improvement I finally bought a new rotor and all the problems vanished. The bike is running strong a year later. However, the girl who owns it is 140 pounds and regularly bounces off the kickstart lever. I told her she needs to put on 50 pounds. A lot of these boyers are 20 years old or more so it's understandable that the magnets weaken. I bought a new rotor from Steadfast for $50.

Buy 2 magnets and replace the magnets on the rotor.
yup, found that here; March 2022 thread:

"... The magnets and screws are available from Boyer and I think are marked for correct orientation. They are quite easily removed..."

Thanks. That looks like a better deal.
