In the process of reverting my '78 R80 back to standard ignition, I've
discovered that the optical pick-up at the camshaft of the aftermarket
electronic ignition came with it's own rotating backplate.

So I'm in need of one of the original backplates, the one that has the
points attached to it, and which is rotated to set the timimg.

Anyone got one of those collecting dust in a drawer?

Try MotorWorks. I'll bet they have them, new and used.

I had a look at their website, which shows used ones at "only" £28.
Which made me wonder if it was made from titanium or one of the rare
earth metals. FFS, to me it looks like a basic, ca 50 mm Ø perforated
iron plate . . . which should be in surplus on the market, considering
how many of those bikes have been converted to electronic ignition.

Simplicity. Originality. To get it running again with minimal effort
when the EI breaks down.

I'm with Olson. Leave it on electronic. It's less likely to break down,
and will run better anyway.

Yebbut, I just don't understand this sort of hankering for something
that "can easily be fixed". My idea of machinery is that it shouldn't go
wrong in the first place, not that it should be easy to mend when it
does.

And by and large, electronic ignitions don't go wrong anywhere near as
often as points systems, require zero maintenance, and make an engine
run better. What's not to like?

Or maybe he wants his classic bike to be authentic.

Plus there's not a lot on the TV at the moment and he might want
something to keep himself occupied! Some people need a mission in
life!

Having had boxers with both points and EI I would want to keep EI,
even if it took me a few weeks extra to save up the money to replace a
broken EI

One coconut to Champ for the correct answer.

The current EI was fitted to replace one that failed in the most
spectacular fashion[1]. Whilst troubleshooting the latter, I came across
plenty of reports of other's EIs that also had failed, or worked not as
good as points, both without and with detailed explanations why.

So I want to see how my R80 runs with points, and if not better than EI,
to keep as a back-up system that will allow me to continue a journey
when EI #2 gives up the ghost.

Back to my parts query; if everyone agrees that EI _is_ better than
points, why is there no surplus of said part, and why can used ones
command prices approaching 1/10 of a SOB?

> >Or he's just eccentric!

I am tempted to take that as a compliment.


[1]Two days before longer journey, after lots of work to improve the
reliability/performance of the bike. But for some reason I let the
aftermarket EI in peace, because "they don't fail" . . . - hah.
