been busy,camera went missing,running on the backup shop camera {-_-}.
doin a  stem swap kz650 to zx636.
had to machine the weld off and then remove the stem.then decided the slickest way to lock it all together was,with a custom machined stepped bushing that i would tig weld to the stem.so that i can bore out the zx triples and machine a step that the step on the new bushing will lock up against.

hopefully these pics tell the story.
