Okay, I know the 77/78 hardchromed. Fork tubes for K models from 73-76.
 What + need to know is,  does the F  models tubes fit into K legs...anyone know for sure?

I use cb550k 1978 tube in cb750k 1974 legs.

When you did that, the tubes were shorter.. Correct?  Or same length?

[BPellerine]

they list the 77/78 tubes as being a little longer but work out to much the same height when assembled.bill

Longer than 73-76?

[chewbacca5000]

I used some 1980 cb650 or 1980 cb750 tubes into 341 fork lowers 73 to 76.  Many will interchange.

As a bonus no top pitting at all.

Here is what they look like installed.  Notice no rust!  They are 1" longer too which will be nice if I ever want to switch to clip ons.

I have someone wants a single,I suggested a pair of late style.
I may have a single, but need the tube to check length.
