So what parts have you guys/gals found to be interchangable between the different years?
Well...
Differences:(CV(most '80 and all '81 and '82's) bikes Vs. Mechanical carb bikes('79 and some '80 cb650's)
The '79 kickstand has the spring on the inside of the frame, '80-'82 on the outside
Sidecovers, obvious difference visually, mount points do not match up.
Seats do not swap
Tanks do not swap
Tripple trees are different spacing, but forks are same diameter.
rear rim swap is straightforward.
Swingarm swap is not, soemewhat involved with this one.
CDI units are same all years.(can use DOHC750/900/1100 units as well)
engines swap all years
heads swap all years
turn signals swap '80-'82, '79's are unique among the cb650's
exhausts are not a straightforward swap.
a '79 4-2 exhaust fits the '80-'82 frame ok. the 4-4 fits the '79, but interferes with the
kickstand spring post on the frame.
headlight mounts are different.
neck bearings are the same
Tripple trees swap easily.
coils are swappable
air cleaners are not swappable.
Inner plastic fender off a '80-'82 frame will fit a '79 frame if using pods, and you want to eliminate the airbox(not a perfect fit, but it works)
And thats just , besides the obvious frame differences.
And that list is just off the top of me head for 650 to 650 swaps i've tried....
Not to mention the non cb650 parts onto a cb650 i have failed at or succeeded at.

Don't forget, thats only for the US version.
As for non US "Z" models, I have no idea. Have YET to get one.
