Not much left.
1. Carbs.
2  Advancer + Points plate (maybe cheapo EBay electronic ign.).
3. New chain (ordered).

Wait...what?  You have a k6 with a chain oiler?  Just checked the sohc4.net model changes and k6 is supposed to be first model to not have chain oiler...?

Very true. I think we went over that earlier in this thread....

Had an excellent 18T sprocket and found a lock tab. The “oiler” is screwed down tight and the jam nut is in Loctite too.

So if you screw down the oiler tighter than Fort Knox it should stop the oiling? Someone mentioned something about them wearing down over time.

Everything is looking so clean. Beautiful to witness

If the seal is still in good condition yes it should shut it off.
My K5 had a bad seal and leaked like a seive.

[BenelliSEI]

Seal is lovely. Cleaned it very well, Added a drop of “goop”, and it’s well “OFF”.

looking amazing! Great work !   When is the first ride going to happen?  Exciting!

Still need to build a set of carbs.

My K6 was delivered with chain oiler, still has it

Interesting, Per. Mine is cb750E-2452000. Close to yours?

The K6 was literally made with whatever leftover parts were available at the time(!), which is why some have [this] and others have [that] part, even in the engines. I find them to be an adventure, myself!

I sometimes wonder if the famous K6 Planet Blue was Honda's "salve" for that? It was an especially-applied paint job, IMHO, and truly beautiful.

My K5 is Planet Blue which I thought was a 1 year color in 75.

The extra key for my K6 arrived today. Ordered Nov. 21, 2023. USPS (First Class International) may have set a new record! Reviewing the scan history, it appears to have spent over two months in a Chicago D.C. Wow!

Spent a few hours diagnosing an interesting problem on my 1976 cb750K6 today. Both front turn signals (the large “pancake” style) contain dual filament bulbs in the correct socket. Solid light blue and solid orange wires are the bright (+) feeds. The light blue with a white band, and orange with a blue band wires feed (+) to the lower intensity running lights. Both lamps are grounded internally and both stalks have a ground wire connected to the square washer under the fixing nut, inside the headlamp housing. Both turn signals work as they should.

The running lights are plugged into the corresponding, matching wires inside the headlamp housing and feed into the main harness. Note that on this model there is no light switch. The headlight and tail light come on with the key switch. The headlamp has the usual Hi-Lo switch on the left bar controls. Regardless of what I did, there is no power being fed to the front running lights.

So I pulled out my Factory Manual and traced the banded wires back from turnsignals. Sure enough, they plug into the main harness (just as I did). Follow those two feeds back through the harness and guess where they lead? NOWHERE. THEY JUST END. HOOKED UP TO NOTHING. WTF? Obviously plans or regulations changed? Complete mystery. Surely there is an explaination?

I made up a solid jumper harness and connected both running lights to the low beam feed. They shut off when running the high beam. They are working now, for the first time in 47 years. Very strange…..

It sucks that Honda did that.

[newday777]

Hmm. They should be working as my K5 has them and work.
Where did you find the dead end at?

Cb759k6 wiring diagram. Look closely. Both white banded wires (light blue and orange) go from the turnsignal housings to the bullet connectors. If you follow them they join almost parallel and then head to the middle of the page and just end. White paper, connected to nothing!

[newday777]

When the turn signal come on, the running light is not powered on that side.
Those wires actually go to the turn switch not a dead end.
I suspect the problem is with the switch as that is where the power is cut off when the turn light is switched on.

Just when you think you've seen everything.....

I have a K4 bars on the bench

Stu…. I stand corrected. You are right. My switch is probably at fault. As the turn signals work just fine, I think I’ll leave my solution in place!

[newday777]

The wires with the 3/barrel go into to the main harness. I don't have an open harness to check where they go unfortunately.
