    79 CB750 - Starting issues, carburettor?

    Hi guys, I bought a 79 cb750 (think it’s a k) about 5 years ago. It was completely disassembled when I got it so it’s been a bit of a puzzle to put back together. I re wired the bike with an M unit, I’ve checked all the sparks and everything seems to be working. I’ve sprayed some starter...

    CB750KZ 1979 and CB750F 1979 Engine Differences

    I’m trying to understand, what if any, difference there is between the engines on the 1979 CB750K DOHC bike and the 1979 CB750F DOHC bike (called the CB750F-A in some markets). I was sure that I had read somewhere that the CB750F DOHC bike had different cam profiles and larger valves than the...

    Issue with Oil

    Wanted - Tool bag for CB750K 10th Anniversary Limited Edition

    I recently acquired a beautiful original CB750K (DOHC) 10th Anniversary Limited Edition, unfortunately the original leather tool bag was not included (most likely lost over the years). Would anyone have one to sell me? I'd love to make this bike super original.

    1981 CB750K CR Special 31mm Carb Setup - Help Needed

    Hi guys, I bought a 1981 CB750K years ago, and I've spent a lot of time rebuilding and customizing it. From the beginning, the carbs never quite worked well no matter the setup. Eventually two different people told me they were messed with too much and I needed a better set. I found a great set...

    Oil tank help needed

    I bought myself a 1979 cb750k. This is my first bike and am in the process of figuring out everything to get the engine running well before getting it ready for the road. It appears that the previous owner removed the oil tank and just ran a steel tube to loop the oil. I would like to...

    1979 CB750K

    I recently bought a project Cb750k and I was wondering what parts will bolt up to it. It is a 79 and I was wondering if parts from an 82 will bolt up. Thanks, CincyKid
