This is going to be my first motorcycle and first build, I'm very excited. Bought some parts along with a cb550 frame with a clean title and will be working on this throughout the winter, hopefully have it done by summer. The lot of parts I bought came with a Kawasaki KZ400 engine, so I'm actually in the process of selling it to buy a CB550 engine. I've cleaned the frame up & I'm ion the process of attaching forks and swing arm. I'll post pics on my next update. Look forward to meeting the community. Also, if anyone in the north New Jersey area wants to give a hand with this project, shoot me a message. I can offer beers and comradeship. :D

Buy a cb650 engine. Fits. Lots (20%) more power.
Electronics are a little different, so get 650 ignition setup.

sorry to hi-jack your thread, but does the cb650 engine fit the cb400 frame? t1 or t2, 1978-1979 or w/e the year that extended from 1978 was...

No. First off we are talking inline fours here and you are talking about a hawk para twin.

there is a fair bit of interchange between models of a common era, but in order for you to know that you need to know which bikes were an evolution and which were a clean sheet design. The cb400T hawk is a clean sheet except for the cb450T which came later. Also some years shared suspension bits with the cb360 and 350 it replaced.
generally as a rule if it came with comstars it won't really interchange with spoke wheel bikes.
Also parallel twin engines will not interchange with inline four cylinders unless you have a welder and a lot of gumption.

so whos got a 650 ready to bolt in. will the 550 exhaust work? or does it need a 650 exhaust? or some abortion of both?

Get early 650. 550 headers fit, so do cb750 carbs.

Anyone need a KZ400 engine?

Off the top of your head, do you guys know if you can put a CX500 gas tank on the CB550 frame??
