1982 CB750F brought back from the death

Got bored yesterday so decided to make a chain cover from some leftover aluminum I had laying around. Pretty happy with the result.

Also started on putting on an hydraulic clutch. Curious about how well it will work. Make myself a bracket to mount the slave cylinder so i didn't have to cut into the airbox and in case it sucks is easily reversible. Still have to route the hydraulic line and bleed the system, but will do that when I take out the wiring loom bacause I need to remove the headlight to do so.

So I got a bit busy last weekend, I hooked up the hydraulic clutch but the master cilinder had a pinhole in the casting, leaking oil everywhere and unable to build pressure. At this point i had it with this cheap sh*t and decided to just bin it.

Since I had to take it out I wanted to do an upgrade and make the adjustable handle I had laying around work on this bike anyway.
The handle is of an cb600F but when fitted to the CB750F housing it sticks way to much forward, so picked up a honda NT650V handle, gave it some paint and put it on together with the original cable. Feels good at least having matching handles!

Also took the wiring harness out and stripped it down, found out why I had some bad connections towards the taillight...

Some old twist & tape hackjob / bodge was revealed and fixed it with new wires, solder and heatshrink.

All taped in and ready to go back on. Connectors cleaned with contact spray

On the 750F I just rebuilt i had some issues with the multipin connectors being corroded, particularly the red one to the cdi units which made it run on 2 cyls for a while!

they’re neater than the mass of bullet connectors on the ‘70s bikes but getting old now

you can pull the pins out, clean and dielectric grease and re-assemble to get rid of the corrosion in those.
 
Far, far from OEM but really good connectors, especially for people like me who are significantly challenged when it comes to wiring -

Wago lever nuts. You trim the wires you want to connect, flip up the orange lever, insert a wire into each of the three holes, and snap back the lever. Rock solid - I used them on the taillight and rear indicator wiring on my 750. The best part is, if you mess up, which I do - a lot - then you just flip up the orange lever and start over. Cheap too.

Wago's do not belong in anything automotive, period!:rolleyes:;)
Solder or crimping is the only way to go in my opinion...
 
I don't think I'd trust those either. I've had issues with even cheap crimp connectors. I use solder and shrink if permanent and the good old vintage connectors crimp bullets or multi spade and socket for things that need to come apart.

Solid opinion my man. No argument there. Just saying that these have served me well.

I think if they are mounted secure and out of weather you should be fine. I just don't like spring loaded electrical connections, or even open ones, reminds me too much of a merrett which has no place on a bike or car but folks use them too.

For sure. Apologies jungalist for wading in with my size 11's. Enjoying the build mate.

Me too, nothing like hijacking a thread eh? I do it way too much. Lets just say the cleaned up harness looks great!

Glad we got the 'right way of making electrical connectons' issue sorted ;)
Not much progress, got cold outside and tackled a few jobs inside the house to keep the missus happy...

In my spare time looking into deleting the fuse box on the steering wheel, trying to source some regular handlebar top clamps. Anyone an idea where to get some for cheap that might fit? As well as a 'closed' center nut on the top triple...
 
I have some GL1000 clamps I could measure. Also I think my CM400T had exactly the same clamp tops. Knowing Honda the same clamps probably are on 20 models and 30 years
 
If they do work Mike let me know - I may have a spare set. Happy to donate them jungalist

If shipping doens't break the bank i'd be happy to, going to measure them up next weekend. Can get hold on a set of a cb400T from the wreckers, looks like i can also scavenge the top triple nut of these ones as the cb750F's aren't capped off.
