"D" Distributor is the way Mr Vincent went,
I still think it's the best for us.
Cheers Bill.

Thats certainly good advice, but out of reach for me. Even a non-refurbished K2F is kind of a rarity here and there are no bargains I know of, not to mention any knowledge about the armature it will provide. So an attempt to collect a bunch of armatures to chose from would be at least a quite expensive enterprise with its own uncertainties. Also stress-testing inevitably requires higher temperatures and for me as a standard user/rider without professional equipment that means "drive it until it fails" (which in my case was kind of fun. I remember pushing the bike home one day and thinking "Man, this thing looks so good its even fun to push it and admire its beauty while doing so"I would use one of those old Lucas armatures (after stress-testing it)
Peter, As for your backfire the other day, Slip the base plate off to check the springs,I think Bill has a good point, but only if you have your battery and charging well sorted out, a couple of years ago I set off on my D Comet, and it started to behave horribly, I turned around about 10 miles from home, and only just made it back, eventually, it was only firing intermittently, and I was seriously concerned what effect it might be having on the entire drive train, and the engine for that matter, as it lurched forward and then wouldn't fire for an age before lurching forward again, made for a very stressful 10 miles, but once home I fitted a new replacement condenser supplied by the Distributor Doctor and normal service was resumed instantly, with a magneto failure I think it would have been a whole lot more complicated.
That characteristic "hot" failure you describe is due to the condenser, not the windings. Again, the reasons are explained in excruciating detail in my thread on Britbike. I realize that magneto thread a lot to read, but it contains actual, verifiable information on the operation of magnetos, not repetition of incorrect information found in various post in this current thread.Most "noteworthy" failures of magnetos I know of are winding-related. ... That characteristic failure is the common "runs until it gets hot, then fails and runs again after cooling down"
Although a distributor and coil is cheaper than a magneto, certainly a wealthy company like Vincent wouldn't have made the switch merely to save money on production costs, and instead an ignition system dependent on a 1950s battery and voltage regulator is superior to a magneto in some way I fail to comprehend."D" Distributor is the way Mr Vincent went,
