Any updates on how the HPI system is holding up?
It’s been working great! Absolutely no issues.

What spark plug are you using on your 81 YZ125? Looking for the right plug to use? Was told a BR9EIX but want to confirm.

I just installed a HPI ignition system on my 1981 YZ125H and it runs like a bat out of hell!!! I had used my original electrical system following a restoration project and it melted down on the first ride. Following a Ricky Stator install and a 2nd used CDI install, with mixed results, I found and ordered a HPI system. Bingo! It was just what the doctor ordered!!! Runs like a champ now!
I have a PVL on my 81 Maico 490. The issue with the PVL is you have to get the flywheel spinning fast enough to get a good spark. Not easy on the 490. I can bump start it really easy though
