Topic: IDK Numero Dos - 1975 Honda CB400F

Deconstruction by crash is far more spectacular, except for the rider involved or the bike sponsor in the case of a race bike.

So again, lacking the guts to try and get the engine turned over as other areas of the bike seem more interesting to me...


I don't know. IDK.
It should be obvious to maybe some of you that I LOVE Home Depot and I seriously walk around there sometimes just to get ideas and the start on some concepts, but this... Flexible conduit? Well, I'm gonna give it a shot. This is actually a nod to some Australians, Salty Speed Co and their delicious rebuild of the same bike.

It is more a stylistic approach than a functional one, for sure. I do have both left/right control wire routed inside the clip-ons but for what it's worth... I'd be surprised to see if my headlight bucket is going to fit against the flex conduit, which I have bent to its max radius - I may need longer reaching brackets to make a decent fit of the headlight assembly.

Also had to fabricate a simple 3-way joint mounting bracket. I think I don't have the right 3-way joint but I think what I have will work. The mounting plate mounts to one of the lower triple clamp bolts and is pretty well hidden.

While I've come this far, I think I'm going to continue working on the front brake and then maybe call the front-end done; before I find some other distractions.

To me that looks like a common automotive store electrical wiring loom, not an electrical flexible conduit.  FWIW

Right, RAF. I was aware of that from the start. I didn't want to totally bite them on that. Besides, to me, their black housing looks like it's kinda just jammed into the ends of those bars. At least mine are somewhat more secure FWIW 🤡

But we shall see. I may have to resort to some of the electrical wiring loom like they used because the flex conduit is maybe too beefy and makes installing the headlight bucket and the speedo a little challenging. But then again, I'm up for the challenge!

A few auto stereo shops or McMaster Carr would have a larger selection of options. If you machined a sleeve that would slide into the bar ends and redirect the wires down. It could be machined in two halves to make it a curved part.  It would take a bit of CNC work y,to make a pair.  It would be custom and unique. You could form the part so the conduit could be slipped inside it with a rubber gasket to provide a water resistant seal.  A butile o ring cord could be used to seal the halves when bolted together. With the clamping holes on the bottom for a socket head screw it would be less noticeable.  Make it from aluminum and anodize it or powder coat it and your conduit for a clean finish, but the powder may cause it to be more difficult to form, in that case it would be needed to be formed and held in the needed shape with a heavy wire when powder coated 
Just some thoughts if you wish to go that route or explore other options...

Try this approach:

Nice 👍🏻

Thanks for the tips, RAF.

I like that, calj. Looks like a fancy Nintendo joystick of some sort.

The throttle side has the "fire" button, and the twist for fun throttle.

Feeling like such a newb, for the life of me I cannot figure out how I ever got the ramekin-looking rubber cup to fit into the master cylinder. It's like trying to fit a square peg into a circle!
I polished, cleaned and lubed the cylinder but the darn cup keeps flipping. It is cup opening on the spring-side, right? Certainly makes a better fit with cup opening up on he lever side...
any tricks here or keep fidgeting?

the "cup" goes the same vay as the one on the shaft...they both push fluid forvard

[minimo]

Right, and that is the cup's opened end in toward the spring... well, I guess I was maybe a little too rough with the figment and the cup now has a tear in it :-( I'm gonna step back from this m/c rebuild a bit

Had to take a long break and now I'm back to blow off some steam (and some sparks).



No going back.

The passenger pegs mounted on the swingarm -- is that stock?

Good question. That's how the bike came to me so IDK

I just Google imaged it and, yes, that's a stock thing.  Bizarre!  I wonder why you'd want the passenger's legs moving around so much, especially when you could mount up the pegs to those loops aft of the rider's pegs.

[minimo]

Agreed, SOHC4 Cafe Racer Fan. Might make for a fun and jumpy ride though, no?

[MoMo]

The loop is only on the right side and serves as a bracket for the muffler.  Swing arm is only place for rider footpegs and whoever riders a 400f with a passenger anyway

Not the smartest design.  FYI - in markets other than the US, people ride two-up on even smaller displacement bikes.

I've ridden two up on a 360. Fun times until you try going uphill on a fast moving freeway

its the erly 400 ..later modells(1976) have a frame mounted pegs.(.so it is in Europa)..mine is the erly too

Like southeast Asia where they ride the entire family up

Those videos with 4 or so people riding look funny, but in some parts of the world, that's the primary mode of transportation for 1-2 people.

in the 70" aut at the farm..the only transport vas a germen Express moped and a bolinder munktell traktor..the Express took the most..3 kids and the forth throving behind on the sled..dad never got a car licens..no need ..living on a small iland 4#5 kilometers

My 400 has been under covers while I've been helping a friend with her 1975 CB360. The kickstart snapped off and I had to pull the engine and split the case... and then put it all back together again; replacing a bunch of parts along the way like the steering to tapered bearings, gaskets, cleaning up oil pump and o-rings, etc. also slapped on a new set of Dunlop D404 - front and rear.
This rebuild went quick. I think I'm getting into the swing of things with these Honda classics😎
