Thinking about a new project

Fucking do it. A cafe racer build is my next project, and the CB is a great platform. If that is a CB, it probably won't take much to get it running- those things were over-engineered tanks.

Does the engine spin? With that exhaust, if the previous owner didn't rejet the carbs it might have been running lean. It looks like a well sorted bike so I would think that was taken care of, but the color of those headpipes may indicate otherwise.

I can't tell, but if it is a CB engine I would think parts would be cheap. There are a number of CB750 motors on ebay for $200 or less. The difficult part (bodywork) looks done. Whatever is wrong with it shouldn't take a lot of money, just time. That is kind of the idea for a winter project though.

It's actually a CB550

im pretty sure the problem either has to do with the starter or the transmission. when i try to start it electrically, it just clicks and when i try to kick start it, i get about 3/4 of the way down before the kick start just stops. i know it's not the battery because ive fully charged it

Does the engine actually turn for that 3/4 of kick lever movement? I'm not familiar with that bike so this is just my gut feeling, but it sounds like it may have a seized engine. I would still look in to parts and mods (big bore kit?) to see what can be done if the bike is the right price. Buy it with the assumption it has a seized motor. If it doesn't it is a bonus.

Yep.

Sounds locked up to me.

Looks like a 750 swap in the making.

I played wuth a 77 CB750F a few years ago that the Mid 70s bike have difficulty with intake valves still is it short money the single cams are cool bikes. DO you know if it started as a F or a K Bike? It would tepmpt the hell out of me. I have to go pick up a 74 Cb750 K next weekend (someone is giving it to me) Know any one who is willing to tell my wife I am getting 5th bike?
