Working backwards

After about 2hrs of trying to fathom the intricacies of the board. I gave up. I've started to work to the board from the destinations and see where we go from here.

Regards

Wiring

Thanks Bruce, It certainly seems the most logical. As you suggest I'll just accept the loom as series of wires that I use rather than a prescribed configuration. I could have probably saved myself the money and made up the wiring. Yes, the board does seem to be set up for battery ignition. Once agai...

R12 wiring HELP!

Hi all, I've bought a new ignition board, a new wiring loom and I've downloaded every wiring diagram that there is for R12's. Problem is that '61' is identified as pole on the ignition board on some diagrams, and no. '51' on others. Am I right to assume that this is a typo and should be '51' instead...

Thanks

Thanks Darryl, I found and old diagram which had the parts in some sort of order. As you would expect with R12's the ignition barrel and key weren't the original BMW type, so I thought I'd check on my other R12 to see how it looked. Surprise surprise it too isn't an original barrel/key! My tan R12 h...

Hello all,

I'm replacing the ignition switch and key barrel on my R12. I have the repair kit and new ignition 'board', does anyone have a diagram or picture of how it goes together?

Regards

R12 prices

Very difficult question to answer. Depends on a number of factors: 1. What country you buy from 2. Condition 3. Originality of bike and parts 4. History of bike I live in the UK. My R12 has had and engine rebuild, it is in good condition, the gearbox could do with a rebuild, the magneto/dynamo has b...

Thanks

Thanks Darryl,

I'm hoping it will be the same solution for both bikes.

Now I can ride them I suppose I'll find out what else needs repairing/rebuilding!

Regards,

John

PS thanks to all the help I've had from all on this forum on my previous posts.

R12 Timing Tool

I am not in the employment of Mark Huggett nor am I being paid any commission but he is now stocking the R12 timing tool. If you search for part number 92 35 3291051 on the extended search page you'll find it.
