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!

new is not automatically better than original.

" I had used my original electrical system following a restoration project and it melted down on the first ride."
The ignition obviously worked perfectly before you got it, then it mysteriously burns up after you remove it and reinstall it. This obviously suggests that one possible reason for the failure is incorrect re-installation.
like i stated, new is not automatically better than original.
PS - One of edisons light bulbs is still burning after 117 years.
A suggestion is to put the stock ignition on it and put a timing light on it. Not start it, but just to give you a reference point. The reinstall the PVL and compare. Adjust the PVL to match the stocker. That may allow you to kick start the bike.
A bit of work, but should get you where you want to be.
At least an idea.
Good Luck!
my 1980 yz250 runs flawlessly and is easily capable of winning expert level races at ahrma, so i see no reason to switch to something else if it ever fails. if it ain't broke, i ain't gonna "fix" it.
i also holeshot 15 newer 250 and 450 4 stroke bikes (that cost around $9,000.00 a piece when new) with my worn out 38 year old 2 stroke at the last trans world mx at milestone 5 weeks ago and again, this is with a 38 year old stock ignition.
also, as i previously mentioned, without knowing the timing curves, you don't know what you are getting with an aftermarket one compared to an oem one.
