Wish I could post a pic of my deserving CB750…

Hmmm....I have a 78 750K, but engine is just an E....

Aren’t all the engines marked “E” regardless of F, K models? I completely glossed over the fact they were different years - too much cough syrup LOL

From what I’ve heard and read, you’ll never get matching frame/engine numbers because of Honda’s QC practice of pulling random engines from the assembly line to test.

It looks like a Nighthawk without the side covers

[emoji1318]What they said

Putting them on “straight” - all four at once - sounds logical, but I’ve always done it one at a time. Start by attaching to #1, tighten clamp enough to hold in place, then the same with 2, 3, 4. You will need to wiggle and finess as you go but can fine tune everything into place once all four...

I first thought you were having trouble attaching the airbox to carbs, that’s why I asked Now it sounds as if you’re trying to attach the box and then put the whole assembly on - am I miss reading that?

Are the carbs already on the bike? Are the air side boots in the air box or on back of the carbs?

Good to know!

I get a drip from there if I let it (‘78 CB750K) idle on the side stand - been wondering about this myself.

For now.... I would make sure the carbs are properly synced.

Of course there are always swap meets - $10

I use Dime City Cycles, vintagecb750.com, and Bike Bandit. There's plenty on eBay too.

Machine shop? Just thinking a half decent one could fab up a new one

If the mounts are the same, I don't see why not. You'll have to probably do an a$$ ton of other swaps as well (wiring) but you're running the entire unit not trying to switch internals.

I suppose. Two almost identical "one offs" just seems like something involving conspiracy theories, not chopper gas tanks. LOL

Saw this at Vintage Motorcycle Days today. Owner had zero clue as to the make of the tank - said it was only one he'd ever seen ("...and I've scoured the Internet." [emoji849]) Do you know? They're pretty cool, and I'm curious.

I felt the same way so I always used the center stand. When I tore the bike down recently, I discovered the "bolt tab" on the kickstand was bent. Straightened it in a vise and it stands taller like it should.

Ok - so my "put the old one back" was 1/2 right! Swapped the original electronics (left) for the new (right) in the new key housing - problem solved!

I think what I need to do is put the old switch back on and just ponder the novelty of the key.

The box says "5 prong", but looking into the old one, there are 6. Any suggestions?

I just installed a new ignition switch - could pull the key out with bike still running - is it possible that's where the problem lies?

My 78 CB750K v2.0

Excellent - Thank you!

Having some minor issues with wiring connections that have me (and others) stumped. 1. Oil light stays lit even when wire is disconnected from crankcase oil sensor. 2. Rear light works as brake light and when key is switched to "P", but not as a running light. All solutions lie behind the...

"F" was the Super Sport engine, correct?

Uncle Sam and the IRS bought me H-man's book LOL K vs F = good news
