Quick dumb KZ1000 fork question

Sorry in advance. My bike is a half hour drive away and my factory manual doesn't list fork tube diameter that I see...

Can anyone tell me real quick what the diameter of the fork tubes are for a 79 KZ1000-E1 (st)?

Thanks!!!

Just double checking what I need for a set of clip-ons.

Never mind, I finally found a reference to fork size in the archives.

Sorry about pulling the trigger too quick on this post.

Thanks!
