Ignition coils

[Dizerens5]

Hello folks, I am wondering if anybody recognises the ignition coil on the photo attached....it's one of the 6v pair off my 1979 R65. I had a mysterious misfire but it seems to have been fixed by replacing the coils with Bosch ones. The pattern pair are painted black end to end and have no indication of manufacturer, country of origin or anything else except "09-205 6 volt standard". They do seem to have caused the misfire but a test meter shows resistance of primary and secondary on both must be about right (I don't have correct figures but they are surely "in the ballpark"). Anyone know where these coils come from and if they are any good?

I seem to remember this coil coming up on the forum once before so maybe a search would find a thread. Here is a what I think is the UK distributor which lists the bosch equivalents.

Probably make niffty fishing weights!

Have heard of phony, cheap-o, counterfeit coils being sold to the unsuspecting. My '83 R65 arrived with two 6V coils attached to the backbone with a single huge hose clamp. Dyna brown done come to town... do dah

Thanks Barry. Based on your weblink an internet search suggests these coils may possibly be made by Lighten Point, a small aftermarket electrics company I've never heard of,  in Leeds (UK), set up in 1977 and now part of Ring PLC, which is pretty well known here, if a bit downmarket I suspect.
Lighten Point claims to make high quality products. If so, why don't they put their name on them?

You might also want to consider replacing your wires and caps.  

If you still have the original BMW caps with the metal shroud, I would definitely replace them with some nice, water resistant NGK caps.

Also, if you have the original wires/caps, remove the wire tip that goes into the coil.  It will be soldered on, so you need to heat up the solder to remove them.  They are far superior to the clamp on type.

Or you can give them a good hard tug and similtaneously remove all that pesky skin from your knuckles like I did.

It's really not a worthy project unless there's a wee bit o' blood to show.

That's the stuff that previously owned bikes are made of!
