    1979 CB750k - Valve Clearance Clarification

    Hmm yeah this ones got about 18.5k miles. But had a refresh at 17.5k with new redone bottom end. Aside from new cam bearings and valve stem seals no other work to the heads though. I had a day this fall where the engine flooded with fuel due to bad float needle. Ran for about 30sec before I...

    1979 CB750k - Valve Clearance Clarification

    Mostly that loose after adjustment using the combo of shims i had to bump the clearances up a bit, that's what i ended up with. I haven't run the motor yet but i did check cold compression (carbs off so no throttle) as part of my winter work and im getting pretty low compression on the...

    1979 CB750k - Valve Clearance Clarification

    Did i pick the correct jets? (1980 cb750k)

    Hey all, I decided to get rid of my stock exhaust and changed it for a Delkevic 4-1 megaphone exhaust last summer.

    1980 CB750k Battery

    It's less about the money (to some extent) and more about dimensions. I can pay 100+ if i can get it within my sizing parameters. Long story short I had a electrical box designed and its a tad bit small for my current 12V-14AH battery (damnit). I can't really get it redesigned anytime soon and...

    Hmm, well it already comes wrapped with some of delkevic's packing, do you think the 4 stroke muffler packing would do a better job? Or is it all the same? It comes with http://www.delkevic.us/index.php?route=product/product&product_id=29501&search=packing.

    1980 CB750k Stock Airbox. What connects to this knob?

    Hey guys, as i was taking apart my cb750k carbs, i realized that the stock airbox has this knob sticking out of the back. It seems as if something should connect here but I have no idea what? Can you guys offer some help? My guess is that one of the breather box hoses connects to it? But i am...

    1980 CB750k Weird Jetting & Idle issue

    Hey Amc, thanks for the response. Also thanks for the correction; we all have to learn somehow. I'll definitely not ride it until this gets figured out. I guess it turns out I've a lot to check up on. I've got a compression guage coming in this week, so I'll check that as soon as I can. I'll...
