Clubman Bars and the CB750

Ok, I have searched the forum, but did not find what I need to know. What size bars do I need for a CB750? How do you run the wires inside them?
 
cb750 are 7/8, as far as the wires i ran mine on the outside of the bars, just notched the controls. it would be a pain to get the wires around the bends, dont think i have ever seen anyone do it.
 
All bikes except Harleys and those trying to be Harleys have 7/8" bars. The wiring all depends on what kind of bars you have. Mine are crimped (cheap) so I can't run full length internal wires. I just put them basicly in and out:

As stated before, the bars for cb750s are 7/8.

I have a '76 CB750, and I just finished running the wires through Clubman bars. You are correct in thinking that the bend in the bar is the problem. It was a total pain the a$$.

I got the right hand control wires through all at once (in the shrink tubing). I tied a shoelace around the wires, fed the string through, and the pulled and pushed the wires through. There was silicone spray involved, as well as a lot of swearing.

The left hand controls are a bigger hassle because there are more wires (11 I tihnk) to get through. I could not get the wires to feed though all at once, so I had to cut the shrink tube and do the wire individually. I tried a lot of variations to get all the wires through (very frustrating), and the best solution that I found is as follows:

  • Cut the shrink tube so all of the wires are lose. You can play with how high up you want to cut, but I found that sleeve got in that way so I cut it pretty high
  • Next run a string through the bars. Something thin, but strong enough to hold up to a lot of pulling and rubbing inside the bars.
  • Tie the end of the string to the first wire that you want to pull through. Then tie a second string to the same wire so that once the wire is all the way through the bars you will have a string in the bars to pull the next wire through with. (The first time you do this, it may save you some time to pull multiple wires through, as there will be lots of room in the empty bars. As you repeat the steps it will be harder to run the wires through and you will need to pull the wires through one at a time)
  • Repeat this until you have all of the wires through

I would recommend silicone spray to help get the wire to run smoothly through the bars. BUT keep in mind that the silicone spray does bad things to any masking tape labels that you may have used to identified your wires with before disconnecting them. That part was the cherry on top.

Good luck,
Matt
