Is it better to be lucky than good ? If you were on Normandy Beach, 6 June 1944, it sure was.
I read the instructions, and they talked about disconnecting the clutch cable and pulling it out of the cable retainer on the forks.
I read posts on here where it was said a 1½" longer cable would take care of that, so I proactively ordered that from Barnett.
And I hoped for the best with the rest.
In my case, I have a number of items I've added, such as the Koso tachometer, and the GI Pro gear indicator, and powered mount for my navigator, and control for my heated grips, and the powered Rivco mirrors, and HEL brake lines.
In general, when I install things, particularly around the handlebars, I leave extra wire.
So in short, after adding the longer clutch cable, nothing had to be rerouted.
