how to improve stock 82' 750 light?

Just got my bike and the headlights are terrible. What is the largest H4 bulb I can run on this bike? is it likely the wiring is bad causing the light to be weak? thanks

 

I've heard two good tips on this. You're talking about the square light, yes?
Unfortunately, that limits the options, as they don't make a modern reflector for square headlights, but..

I've heard you can bypass the computer by running a headlight relay straight from the battery to the headlight, search around for that, you will get a headlight warning on the atari, however unless you do some kind of work around. Also, you can just put a Sylvania Silverstar bulb in there, that is the easiest improvement you can do.

Also, you could always get rid of the square housing and get a modern modular round headlight, losing the silly auxiallary light, that does nothing as far as I'm concerned, anyway. What you cannot do is simply put a giant wattage light or lights on these things, they just don't provide enough power from the alternator, as I understand it.

 

Start with a thorough cleaning of all the connections, then make sure the up/down adjustment is good. Make sure the wiring is up to task first, then work on the bulbs. jmho

 

I just combined these two. I haven't set up relays yet, just re-wired so that the wires from the headlight switch go directly to the light instead of through the computer (it's the way the 650's and '83 750's are wired), and also swapped in a round headlight lens and bucket. The difference is literally night and day, and I fully expect it to improve even more once I get the relays hooked up.

I didn't have to worry about the computer warnings, because I swapped in a set of gauges from a 650 at the same time. No more fishfinder + round headlight with modern lens = a bike that looks much better and is much less scary to ride at night.

Whatever you do, don't simply put in a higher wattage bulb into your current setup. Best case scenario: You burn out the computer in the Atari. Worst case: You set your bike on fire.

 

thanks whats the larges size stock headlight and bulb I can run without straining the charging system? i also wanted to hardwire a gps. What are you running?

 

Headlight relays are the way to go, mine went from candles to floodlights just by fitting relays. Run one nice heavy wire from the battery to the relays and you use the existing wireing to turn the relays on/off. Plenty of room behind a square llight. Just fitting a bigger bulb won't solve the problem.

 

Don't go above the standard 60/55 without relays. The charging system on these bikes was pretty much at its limit in the stock setup - and that was when the bike was new, and the wiring and connections weren't 30 years old.
