Gooday Noel,
Solution is possibly at hand. I still have not found all of what you are looking for since the failure of your CZ ignition system at the DT NATS. I will express mail this to you tomorrow. You should have it on Tuesday. Hopefully that will allow you enough time to have it fitted in time for racing at Lakes next weekend.
When I find what you are originally looking for, you can return this. I will find the rest soon.
Noel I removed this from a running machine that I was the last to ride.
A HISTORY OF THIS MACHINE AND ITS IGNITION WOES.
This machine was purchased new by Ken S------D long time employee of FRASERS NEWCASTLE. Ken campaigned this CZ400 extensively in short circuit and motocross at venues like Salty Creek, Mulbring, and Cameron Park etc. etc. Ken had fitted additional shock mounting points on the swinging arm.
One position for was for MX shocks and the other for SC shocks. We bought the bike of Ken at Christmas 81. Ken had re-ringed it, but amazingly it was still on the original engine and on the original bore. Kens best improvement=Mikuni carburettor.
An Old Mate and I shared a hundred acres with its own MX/GRASS tracks, adjacent to Stockton Beach Dunes near Newcastle. We flogged this machine hard for the next twenty months. A lost of spark led us to a failed condenser. The Ignition failed again after bathing it one day. After a week and five flagons of green ginger wine, the machine started again. We discovered that the twin secondary coils underneath the tank had hair line fractures in the Bakelite caps and they were frightened of moisture. We replaced the twin secondary car style coils with a single coil from a Honda CD90. We then continued our near daily routine of flogging this machine until its first piston cried “no more”.
CONCLUSSION; this CZ400 that I still own, is the most DURABLE and pleasurable motor cycle that I have EVER owned.
I will post that EXPRESS first thing in the morning Noel, Mick.
