    Boyer ignition

    I was going to install a Boyer electronic ignition on my 78 r80/7 today but noticed that the instructions recommended to install 5k ohm spark plug caps with copper leads. I am looking for advise on where to buy these. I found a set on euro motoelectric site but they indicated they are for later models. Any help will be greatly appreciated thanks

    The /7 machines came stock with 5K ohm spark plug caps. I don't know what is meant by copper leads...I suspect they're thinking of the earlier 70's airheads which had 1K ohm caps. The stock 5K ohm caps are blocky...you can get a sense of it in this photo:

    Read here. I think this will answer your questions about different types of spark plug wire. http://www.magnecor.com/magnecor1/truth.htm

    I have a Boyer on my R80/7 also. Love it! I would recommend you buy your leads directly from Rick Jones at Motored Electric. Scroll down and you'll see he has plug wires specifically for airheads in various colors, with 5 ohm NGK caps for $35. I bought a set to match my /7 in blue. They're high quality and made with copper core wire leads. They work great with the Boyer. www.motoelekt.com/ignition.htm

    Unless I am mistaken, the stock BMW caps are also copper core leads with 5 ohm caps, but are styled as you see in Kurt's photo in post #2. It's just a matter of preference and cost... you can get those from Ted Porter's Beemer Shop (www.beemershop.com) or MAX BMW (www.maxbmwmotorcycles.com).

    I use the Boyer Electronic Ignition on my /7 (a 77 R100RS). This Boyer system came from Rocky Point Cycle.
    I am using spark plug cable from Re-Psycle BMW and also have a spare set from MotorRadElektrik. The plug
    caps are NGK and have the 5k ohm resistance, these were from Re-Psycle. MotorRadElektrik also has them.

    Thumbs up +1 on Boyer Bransden

    A Boyer micro digital ignition along with a new Dyna coil, NGK caps & wires from Rocky Point Cycle were installed on this '76 R90/6 10 months ago. 5 out of 5 stars!

    The heads were rebuilt by Ted Porter, and Siebenrock 1000cc barrels & pistons installed less than 400 miles ago. Still on the break in , but from the seat of the pants. me thinks it's x 5!
