Back of the oil bag

Chase this hole with pipe thread tap.


Smoke these fittings down.


Looking good, but we are still short a plug for the last hole.


Now to plan our all-thread studs for the back of the oil bag.


Center punch...

Center drill...

Drill...

This one doesn't line up, but other side did. We had to put the hole in the frame in this location, so something is not quite even, either the frame or oil bag, no surprise either way.

Make a new hole for it.

Now we can put the nuts on the mounts and cut the all-thread to length. I love my right angle attachment and EZ Lock cut off wheels for my Dremel.

We'll need more nuts, washers, and red loctite , but otherwise we're good to go. Plumbing the oil lines and running the wires will be next.

Mounting the oil bag and coils

Now to figure out this front oil bag mount.


Here's the strap for the crosspiece.


Tick marks for our knotch cuts.


Make a cardboard piece to the same size and shape to check fit our plans.

Looks good.

Wow, check this out. The bike traveled cross country in a trailer just fine, but the I-40 crosstown knocked it over in the trailer and bashed the points cover.

Luckily, the points still look okay.

Bierkan hammered the dent back out., mostly.

We need a bend in these to fit the headlight right.

Fastfoward a day or two, and Beirkan took the oil bag front support to a band saw and cut the knotches.

Set it in.

Bierkan studies the welder's set-up charts, then set every to MAX. I think.

Time to get to it.

Try to tackt it in place.

That didn't work well because of all the paint still on the frame. D'oh.

Now it seems to work.

Tacked in place.

The little seatpost support piece won't fit, but we don't really need it. Mark the spot for the tank.

Center punch the center of the mark.

Center drill the center punch mark.

Drill it.

Hey, let's cover those carbs and the alternator area so we don't get more chips in them.

Now let's finish the hole.

Perfect.

Bierkan pulled the tank and finished the full welds for the bracket.

Now to the back supports. The plan is to use all-thread to support the back end. Two five inch sections should do it. This is how I cut all-thread to length. Double-nut both sides of the cut line.


Then cut it. I used angle grinder, but I have used a hacksaw to do it before. Taking the nuts off helps to clean up the threads at the cut, too.

Two nice 5 inch studs. We'll see if this works out later.

Mount the new coils and dump the old ones.

hhmmm...

I believe this is under the stock mounting bracket, but the spade style terminals were interferring with the stock bracket and this way seems to fit, okay.

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.
