Tri-Spark bites the dust two years in

[Schwany]

Nice to hear that some have many troublefree years with a Trispark,
but how many km/miles?
1000, 10 000, 100 000 ?

I would like to hear if someone has done more than, say, 20 000 miles or more on a Trispark.

I'd also like to hear the high milage success stories and at what location on the globe with this ignition.

I’ll never go near Tri-Spark ignition.

You and other guys have convinced me it doesn’t have the reliability of cheaper systems such as Boyer Mk4 and Wassell.

My seat of the pants meter regarding this issue that is not supposed to ever happen says it will eventually not recover when cooled down if it is an 0005B and ridden in the heat a couple more times. That's based on my experience not BS.

I'd be curious about this. I've stood off the points cover maybe 1/4" so plenty of cooling air should go through and over the unit; I should think the points cover itself (which is a finned Dunstall style) would stay cooler too given only points of physical contact now are the mounting screws and the nuts I put between cover and case to achieve the stand-off. Water another issue, of course....

But should I be worried that the prior two heatsoaks/failures have permanently damaged the stator plate (which I installed in 2012, I think even prior to the 0005 - there is no numbering on it (and no test button)?

Thanks all - BK

12 years is a long run. I'm going to be lucky if I know where I'm standing in 12 more years.

My response is going to be skewed off the end of the negative scale. Would be better if somebody else gave an opinion on when to start the worrying.

I can say it is not normal for any ignition system to stop working in a properly installed electrical system.

12 years, but probably no more than 7000 miles (which is unfortunate on any number of levels!)

I like what comes in the Vape Wassell box. Plenty of wire to get the job done and connectors on the wires out of the control box to make the install simpler for people that get confused by wiring. If one has the room for those connectors that is. Looks like a better design and possibly newer tech components on the stator plate than Boyer and Pazon.

I have a Boyer MkIV and I was seriously thinking about reinstalling it, but one of the magnets on the rotor is weaker than the other. I had a MkIII and need to see if I can find the rotor that came with it. Anyway, more first world problems to ponder.

It is possible to buy replacement magnets from Boyer if you email them.
Personally I think Boyer get a bum rap. They have probably sold more ignition systems than any other aftermarket provider, and many folks report they are still working after decades of service.
The real Achilles heel (on the Commando anyway) is the tails on the stator shaking about causing the wires strands to shear within the cable insulator. I modify them with a surface mount screw connector (like the early Boyers had and Pazon still have).

You can see one here (which is still available )

I saw that Boyer stator mod post when you made it. I could do that easy peasy, but I have some other stuff that would prevent the shearing without breaking out the solder sucker.

Turns out the Boyer MkIII version rotor magnets are just like the magnets on the MkIV rotor. Either of them would probably work. I have to talk myself into doing the rewiring to install it. Kind of low on the priority list right now.
