hello lilhonda, I’m mike from vancouver canada , past years I’ve been working on this bike that now starts on a single kick , drives like butter. I discovered this forum & looking for an idea to upgrade the headlight from its current sealed beam to an LED, the current headlight is burnt out & seems to be a pain , any ideas on what’s the best way to upgrade?, greatly appreciated.

LEDs really need DC to operate properly, efficiently and last. Most of the LED options out there are available in 12v flavor only. Converting the electrical system to full-wave rectified DC is a fairly complex project.

Easiest/cheapest way to go is with an aftermarket reflector assembly, for your K1-later headlight shell. That'll allow you to replace the stupid-expensive sealed beam with a $3 bulb...that'll probably put out more light anyway. You can experiment with varying bulb wattages, as that will trade brightness for longevity...or vice-versa.

If you're dedicated to trying an LED and can find a 6V version that fits your HL reflector, then you could experiment by adding a second rectifier, to the yellow HL lead...which normally feeds raw AC from the stator, while the engine is running.

BTW, that' looks like a really clean `76.(y) Don't see many of those.
