Sesman:
Thanks guys. I’m about to delve into the mysterious rabbit hole of e lec tronics.

Back then, the product I wanted, was not around. This because it was my desire to preserve the breakerpoints, so I could return to stock in case of failure. In those years I traveled adventurously in far away parts of Europe. I realised that my experience with that Velleman kit under the hood of my car had been good, so why not make a double one for the CB500. I now had the list of components and the scheme and I thought it would be a nice challenge for a noob like me.
Buying components separately and solder them to experimentboard like I did, is ofcourse the cheapest way, but to arrange it (the experiment board) is a bit of a puzzle and then squeeze them (it's two ofcourse) into the right box, also was. I've managed, but now that I will make another, I have chosen the next level in cost and have honoured Velleman by buying two sets of the K2543 kit. Then you have the prints and soldering the components is a piece of cake. So far I have never read something negative about the K2543. It's a very popular mod and the kit is much praised. The graphs I showed above were the resuts of a test a Dutch engineer has carried out with a MG sportscar. He is a member of a MG club.
Then you only need the appropiate box. I suggest aluminium, so you can use bottom and lid for the power transistors to dissipate heat, in stead of those exaggerated cooling fins.
For an initial test I had the box under the rubber strap that holds the battery in place. Once I had noticed that the unit still had not moved a mm, I decided to leave it there permanently.
Again cost wise, Hondamans is a good alternative for a reasonable price.

If anyone has a design they want to make up ... I can do a proper glass PCB

Forgive me my ignorance, but what is a glass PCB? :-[ Can it break?
