I don't know about that...but, Thanks!
There's nothing going through the grommets on my bike. I specifically asked the previous owner...the
original owner....about anything he had changed on the bike or that deviated from stock. He never said anything about the signals being off, forks being out, etc.
I'm told the wires should run through the grommets. I have a '78 550K and it doesn't have the grommets. The wires just snake down between the fork ears and fork leg. I believe that, if I were in your position, I'd run the wires through the stalk and then out the grommet. It'll at least offer a little protection against chafing.
