My experience fitting electronic ignition to my B40

[highboy_coupe]

My points were never quite right, I expect there was a lot of wear, I couldn't get it idling right and although I was spot on with the static timing it would wander at idle and cough and stall randomly even when warmed up. That often caused annoying junction kickstart sessions (the kickstart also chose this exact time to lock up at the top to add to the fun).

Of the various choices I decided to purchase the Vape kit sold by Wassel, my reasoning was that the components are encapsulated in resin and there aren't any exposed dry joints on the board. I felt this gave it the best chance of surviving the vibrations.

Fitting was very easy, my old points plate fell out of the taper with a slight wiggle, the cable wasn't quite long enough to be easily routed through the inner case (and I didn't wasn't to breach a perfectly oil tight seal either to be honest). If I'd been more professional, or the owner of a had a shinier bike I would have extended the cables and done it properly , but as I am neither I Dremmeled a little notch in the case under the points cover.

Wiring was also easy, I made a point of giving the coil a nice big positive cable all of it's very own direct from the battery, as although the nest of wiring that exists on my bike provides several questionable earths, they are akin to oily old string at this point.

After spending an hour or two and a beer or two deciding where to mount the tiny little box I was done, and the only other thing I decided to do was open the plug gap up a bit  to .40 and index the plug to give it the best chance of making bangs.

I am really happy with the static timing, I can get the idle really low (for no reason other than to prove to myself that the cost was justified). I need to time it with a strobe at some point, but here we go, a good start:
