CB750K6 Headlight Mainbeam Button Spring
« on: July 07, 2026, 10:46:54 AM »
Hi all. My K6 is still going strong after much work and re-furb 3 years ago.

I had a failure of the horn button, on the left side handlebar switchgear. A soldered terminal had dried up, which I fixed. However, when putting it back together, the tiny spring on the headlight flasher button flew off, never to be seen again.

I have cobbled something together using a spring from a ballpoint pen, but it is too large (diameter) and doesn't stay put. By any chance, does anyone have a spare? If not, could anyone recommend a source for a suitable replacement?

Many thanks,
Martin

There was a seperate part number for the spring on the starter button on earlier bikes, look at a 72 500. That might fit and last time i looked was still available

Thanks Bryan. I have searched on that part #. In Google and David Silver, both come up with a rotary blade.
