Hi All,
I have just joined. I have bought a CB750F1 this summer.
I haven't ridden it much as the headlight now doesn't work.
I have carried out fault finding and one of the wires between the right hand on/off switch and the headlight is broken.
I fitted new throttle cables athe week before so suspected that I had maybe broken a wire as I had the force the two halves of the switch apart to remove the old cables.
I imagine it will be quite awkward to withdraw/refit the wires through the handlebar.
Any advice will be welcome.
Ride Safe. Mike.

Welcome to the Forum Mike.
From your testing is it definitely a broken wire as a poor contact can be a likely cause?
If you intend to repair the switch threading the wiring back down the bars is not as dirricult as it sounds.
If you attach a piece of string to the end of the wiring making sure its taped in place this can be pulled through when you pull out the wires. I have used the old fashioned spiral curtain wire that you hang net curtains on that is then attached to the string to pull the curtain wire through. Then tape the curtain rail wire to the switch wires to pull it through. It helps if the wires are warm so a couple of hours in my airing cupboard or heated with a hair dryer to make it more pliable helps. Final trick is to use an Aerosol of Silicon Spay it lubes the handle bars & loom making it easier to pull through.

Ted,
Thanks for your reply and advice.
One of the wires is broken, all the contacts are clean and good, I have tried a bridging wire between the contact and bulb and it lights up ok.
I was thinking of tying string to the cables to pull it all back through.
I will definitely try warming and silicon spray.
Mike.

Welcome Mike really nice looking bike has it been recently restored prior to you buying it or is it your own work ?

There is a thread in Tricks & Tips on pulling the wires through.
I can't post a link from my phone it's on the first page.

Thanks for all the comments.
The previous owner restored the bike. He has achieved a very nice rideable bike, which is what I wanted, not so good that I would be scared to ride it. It also has a standard exhaust which are now unobtainable.
I haven't the time, patience or skills required to carry out a resto although I think I can maintain and carry out a few improvements.

Mike,
welcome to the forum.
Your bike looks good and perhaps falls into the same category as mine, 'not so good that I would be scared to ride it' .
Anyhow I know what you mean, because I have two other fully restored bikes that I'm scared to turn my back on when parked up for a cuppa during a ride out.
Hope your F1 gives as much pleasure and carefree fun than mine does.

Welcome to the forum Mike. That's a tidy looking example of the F1, always a nice looking bike especially in the maroon colour.

Hey Mike, what is the alloy trianguar part attached to the front footrest for is it so the rear footrest isn't attached to the swing arm?
