Nope I'm not sure if that really was the cause. Just another guess in an ocean of useless guesses.So you gonna change the thread title to "I Made My Tri-Spark bite the dust two years in" ?

I remember a little about your situation.Speaking of Useless Guesses, I had similar symptoms on my Mark III, which nearly drove me and a mechanic to drink, but eventually were traced to a faulty kill switch. You mentioned a rewire, and simplified wiring, but is there a kill switch lurking someplace?
Did you consider "elekronik saches "I remember a little about your situation.
No kill switch. It was a magneto flat track bike before I got it in crates. I did have a kill button on it then. I did the simplest wiring possible to get it running originally, and only made minor changes when removing the magneto and initially points, later EI.
This is a done deal for me. It's dead non-functional and parts are ordered.
I'm not the first person this has happened to. I'm lucky it lasted as long as it did, and very fortunate it finally died close to home.
I am getting the newer version Tri-Spark ignition, which is not my normal. I'm usually once bit twice shy and would get something else, but I like the ease of installation and LED timing set up feature.
I've never heard of them, or millions of other things.Did you consider "elekronik saches "
Virtually the same spec as trispark

I'd have to make space for the external box and all that wiring.
I think I can get more life out of the TriSpark second time around. Plus installing another one will be a piece of cake. The only work will be making a bracket to mount the larger coil to. I'm getting the same spec coil Matt uses with high success, so I might as well give it another go.

Very nice arrangement across the board. I really like seeing clean work.I forgot I’d put this in the media !
Here’s the 3 very high output coils fitted to the Beeza triple, made possible by the single spark Tri Spark firebox. Worked well:
I was thinking of at least making a bigger drain hole at the bottom of the points cover.I know a lot of folk don’t like having the EI brain in the points housing coz of heat etc.
I’m not convinced it’s an issue. Modern electronics are made for it, coils are built into plug caps and buried DEEP in DOHC cylinder heads for example.
Mine has done LOTS of track time, and it’s come back from some sessions VERY hot. I did think about taking the pints cover off to aid cooling, but I basically left it on as a test !
There is one deviation of Schwany's bike to most other Nortons: His is an all-alloy engine. The aluminum barrel is an excellent heat conductor, and I expect the bottom end to become hotter because of this. Additionally, running a prolonged time at low speed will necessarily channel even more heat into the crankcase and timing chest.I’ve never measured either, but I don’t believe a Norton points housing gets hotter than the spark plug area of a modern cylinder head. But I’m only guessing.
Stay at home is my first thought on avoiding engine heat.There is one deviation of Schwany's bike to most other Nortons: His is an all-alloy engine.

A few steps may be taken to avoid this likely problem. Schwany probably knows which, so I won't make any suggestions.

Is that something that’s available to the great unwashed? Or are they reserved for cNw owner aristocracy ??I bought one of Matt's slotted points covers - to be sure, to be sure!!

How about putting a washer on each of the screws between the cover and the case? No permanent change made then.I bought Matt's but a bit of careful drilling (3mm) fore & aft would suffice admirably
I don't mind grinding some slots into the cover and putting fine mesh stainless screen on the inside to keep the small bugs and sand out. I don't ride in the wet. I'll add another cover to my AN cart.How about putting a washer on each of the screws between the cover and the case? No permanent change made then.
I seem to remember it being suggested to run an additional ground wire to the Tri-Spark.
