Title: Route of the loom
Post by: PHILIP2908 on January 23, 2021, 08:21:17 PM

No not jeans. This is a head scratcher for me as my DK Special from the USA has been thrown down the road numerous times and suffered less than perfect rebuilds after its many accidents.
One example of this I the way the loom passes beneath the tank. Currently it is squeezed though the triangular gusset just behind the coils. This interferes with the operation of the push-pull throttle cables to the extent that the throttle will not shut on it own as the cables are kinked. There is just not enough room in there.
One of my lockdown projects was to change the handlebar from the horrible USA aftermarket ‘cowhorn’ bars into a more European and flatter spec; I’ll do another post on that as that is proving to be a right giggle as well. This necessitates the disconnection of all the wires in the headlamp shell and I thought I’d re-route the loom at the same time as everything was undone.
The question I have, is, should the loom that runs from the battery area to the headlamp, be routed:
   -  Strapped to the thick top tube that supports the top of the headstock
Or
   -   Strapped to the thinner lower left hand tube that runs under the tank

As always, all answers gratefully received.
Thanks in advance
Phil

This is mine on strip down, I bought the bike new in 1976 so it was as per Honda apart from the piece of inner tube to stop chaffing, its a 76 750F1 may be different to K's

Here’s a couple of pictures taken from my CB750F2/K7 workshop manual showing cable and wire harness routing, I hope that it helps.(https://uploads.tapatalk-cdn.com/20210124/76728f26af00c87ee05d8e9d11e49fa7.jpg)

Hello,
Dennis & Leadnaval: Thank you both; really helpful. I know what I have to do today - extract the loom from beneath the coils (which will have to come out as that's what's jamming the throttle cables and everything else in that triangular gusset) and lay the wiring as shown in your photos/diagram.
Thanks for taking the time.
Stay safe.
Phil.

Hopefully these images are a bit clearer than my previous post.
