Topic: 1978 CB750K Project

I had a 1975 K model in the seventies, and loved that machine.  It was my ticket into manhood.

Fast forward.....looking for a bike to buy, a friend from another forum offered to just give me his.  I took him up on the offer, and had it shipped to me from Arizona.  Upon inspection, I wa pretty impressed by the condition.  Thank you, BlueSkyJaunte.  Thank you very much.

Here she is, pre-bath:

She was a dirty girl.  I like dirty girls.  I like hosing them:

Oops.  Forgot to post pics.

The PO said the front brake needs attention.  I wanted to also check out the chain and sprockets.  I believe the front sprocket cover cannot be removed without first removing the shift linkage cover (according to the manual.  This has the 630 chain).  Throttle action felt very stiff.  So anyhoo.......by the time I got too drunk to continue, I had removed most of the parts:

The battery tray was not beautiful, having been moistened by battery acid at some point.

So I removed it, bead blasted it and shot it with some paint.

The carbs seemed pretty clean, so I will not re-do the PO's carb rebuild job.  The jets are stock size (105).  I sourced a stock air box from a '77 F.  The bike came with three spare banks of carbs.

My ticket to man hood was a girl named Rosemary but there was a Triumph 250 involved............wonder where she is now ( the Triumph i mean).
Good score on the bike and it looks great! are the pipes in good shape?

[Rosinante]

That's where she sits today.  Getting the air box on, with those rubber thingies and clamps that go on the carbs, was not easy.  The chain they sold me at the dealership is WAY WAY too long (96 instead of 88).  Someone needs to tell the parts guy that they're not "all standard" like he said.  That'll be me.  Waiting for a few other parts too.  (gasket for linkage cover, caliper seal, battery strap, etc.)

The caliper piston is terribly pitted.  That part is NLA.  But.....somebody in St Louis is fabbing pistons out of 304 stainless.  The good news is that this piston will never need to be replaced.  The bad new is that, with shipping, it was nearly $90!  I will need new tires, I think.  Tires are important, in my humble view.

I still have not heard this bike run.  When the rest of the stuff comes in, I will finish putting her back together and we'll see if she runs.  Compression feels firm, using the kickstart.

Ahhh.....  I remember someone named Jeannie.  Wonderful memories.  But.....ahem, this is a motorcycle forum.

Yeah, the pipes are in pretty good shape.  As I inspected them, they do seem to be succumbing to some rust, and there are a couple of very small holes, but they seem good for now.

I have the same year and model as you.  I have some stuff left over from when I restored mine, shoot me a PM with your needs.
