Boyer ignition?

[equipo5]

Does this look like the pre 79 BMW Boyer ignition to you?

Removed link.

These are probally 30 - 40 yrs old but seem to working ok.
Anyone know any good sites on how to adjust timing and measure dwell with these?

Thanks and cheers

Can't see them as a scam for a fake Windows repair comes up. Now I have to scan my computer to be sure.

Removed link. Just googled "photobucket Virus" and there are lots of warnings which I was not aware of before. Sorry about that.
My computer scan came up virus free.
Hope yours is OK.
Cheers

Boyer ignitions should be timed on the F mark. Don't worry about the actual revs, just set the Boyer on the F mark when the Boyer stops advancing. Ignore the S mark, especially if your Boyer is a Microdigital.

Older Boyers like a healthy battery, they revert to full advance if the voltage drops below about 9-10 volts, later models have fixed this.

Hope this helps

What, the F..... and forget about the S. Thanks for the tip Charles.

Just saw your post Steve, would have been a welcome break from gardening duties today.

Damn.

Well, we fiddled with it a wee bit today, but not the timing. Flushed the tank, added Karcoma taps and new fuel lines then reset the float heights. Both needed a tweak, the left more than the right.

That seemed to help as the bike started and ran better after re tuning the carbs. Then we went for a ride to a local brewery. The bike ran fine and didn't get any more tweaks!

And it was a nice warm day with blue skies an' all!
