Figuring out the 750 wiring and oil plumbing

Looks like we need a brake light switch that will fit that.


Let's roll the bars foward so we can get at the wires that are already in the bars.


Ohm check to see what is what. A manual might make this easier, but we have no idea where these handlebars came from.


Trying to figure out the left side is completely fruitless, so...


We'll take a peak to see if can figure out the colors from the back of the switches.

Now we're making progress, so I'll take some notes and make some labels.

Okay, two things are kind of wierd. This on-off switch on the right grip. We're guessing headlights, but we can't find a 750 wiring diagrams on-line with this switch even the earliest ones. The other wierd thing is wires going to the clutch lever. I have seen safety switches on clutch levers, but again not in any 750 wiring diagrams on-line.

Labeled and ready to go. Now we need to plan the rest of the wiring and built the harness.

Now to the oil bag. It has four threaded bungs. Two with snorkel tubes and two at the bottom of the tank.

The holes in the bottom are the gravity feeds to the engine. Not sure why there are two, we will only use one. One snorkel should be longer that the other. The short snorkel is the feed back to the tank and the long snorkel is a vent. We tried to use a mirror to find the long snorkel, but...

we couldn't see them, so will filled the tank with water. The short snorkel should flow first. Amazingly both of the snorkels appeared to be the same length. So I guess either fitting could be either oil line.
