Ladybird book from 1962 before all of the PC brigade b*llocks. bit of sal-ammoniac gel never did anyone any harm ;D ;D

Guess I’m buying the Velleman kit and some ear plugs…

I can remember trying to make a lemon battery from that very book with my older brother. Managed a whisp of a glow from a bulb from his Lego set! kept us busy all afternoon though if I remember ;D

Electronic Ignition.
I’m intending the replicate the Velleman product, but by buying individual components rather than the ‘kit’. In doing so I’m going to build 2 systems. One for the 500 and one for the 550. The way I see it it’s cheaper than buying OE capacitors and the avoids the concerns over unreliable capacitor copies.
Although the Velleman item is good value in my opinion at about £35 per bike.

How are you going to replicate the PCB Phil? Kit's look pretty good value to me ..It might be worth using a purpose-designed transistor though.... the capacitor value they are using is almost the same value as the one on the standard system, so I would either not include it or disconnect the Honda one. Retaining the Honda one would mean you can easily revert back to the standard system though .looking at the one in the kit, it looks pretty decent BUT I don't know it's voltage spec., so with a bit of ingenuity , and assuming it's a high voltage cap., you could wire the system so that if you revert to standard you could use the on-board capacitor to replicate the function of the Honda one. If you want me to test your Honda OEM condensers just send me them and will fully test with my insulation tester.
I just measured a CB500/4 condenser and it will fit in a large letter with a bit of ingenuity. I will stand you the return postage.
Sesman:
Ok, Ash.
Thanks for the offer; I may take you up on that.
I’m a bit busy at the moment so I’ll be in touch when I’ve decided on the solution. I’m favouring buying the self assembly kits, retaining the original capacitors unconnected if serviceable, but crafting a way of quickly reconnecting them if required.
