Hearing on that, I have Elsinore's and YZs
My Elsinore's over 35 years and multiple bikes, I have had one source coil fail and that was must likely water damaged prior to me buying the bottom end and running with the stator
also had a issue with advance curve on one, tried all new electrical components which didn't fix it, plugged in a early 80's Suzuki RM cdi ( some stator manufacture ) and presto advance and retard curve for my big bore & stroker not a 125M. "sweet now"
YZ's on my thrid cdi failure, YZ B models with the CDI at the steering head are a issue for sure.
Pulsar coils on the DT360, MX400b to YZ400C so hard to find.
but with all that we keep doing it and coming back for more.
I have often thought, the 70s was a great era in regards to parts available today, dealers posted orders for parts and ordered parts that come in bags of ten.
The 80's saw a charge in logistics, fax machines and dealer stock levels.
The 90's saw a charge where you paid a deposit on the parts awaited for it to come from ex east.
how there's no dealer stock you pay in full, and in WA " Wait Awhile " is very true.
my Elsinore's still have a good supply of parts today 47 years on thank you to the internet, trying buying water pump parts and rear shockie and or fork parts, and power valves in 17 years time for early 90's bikes.
Buy up now and keep what you have but " Ride them don't hide them" and keep living the dream
