Interesting to see the elongated shape of an early Boyer brain box. The only examples I have ever seen were the smaller squarer examples that came later. This article was from 1973.
Anybody out there still running an original brain box like the one in the article?
 
That was for a Triple. The first Boyers my house mate and I got in about 1974 were Mk 2s. These had the electronics in the points cavity. There was an aluminum ring that extended the points cover out about 1". These would go haywire when it got hot so we sent them back to England not long after getting them. We were sent Mk1As which were just like the Mk3s now. I used the Mk1a for about 35 years and went to Pazon Altair, then Trispark.
The electronics box for the Mk1A and Mk3 was the same small one.

Missing a few bits like the standoff alloy casting spacer ring to give air slots for cooling of the heat failure prone electrics.

Wow, N-V supplied Boyer kits ? I didn't know that. I know there is mention of them in the manuals. Were they ever fitted from the factory?

No idea, got the pics off an ebay listing a few years ago and I have an original setup off a 72 Combat with cooling ring but that would not be factory fit. Possibly available as a Norvil option which I thought I saw a reference to once but not got a hard copy of. Note the slot in the bottom of the cooling ring to let the water out ;) .

I don't know what model my Boyer is but it is very reliable. My midrange jetting is very lean, so a stable spark is critical. I don't have hear problems because I use methanol fuel. Petrol can cook your motor. When you come back in from racing when using petrol you can often hear your motor clicking as it cools-off. If I could not use methanol, I probably would not race. The Commando engine seems to love it. In Australia, we are lucky - there are still a coup[le of classes in which it is permitted.

I have a Mk IV Boyer in my Commando 850 (converted to 750) racing sidecar engine. Absolutely brilliant and so easy to set up (and alter if needs be).
Service and support top notch as well. Price (in comparison with other products) is pretty good...
