'81 kz550 LTD mirror MM size

Hey, anyone know what MM size threads are on a 1981 KZ550 LTD? I was thinking they are 8mm, but I can't remember. Need to buy some aftermarket mirrors and that's kinda important to know.

Thanks!

Nevermind. Just found my notes I lost, it's a 10mm.

But some have left hand threads, while all KZ mirrors are right hand threads.

But of course I can't remember if it was Honda or Yamaha that used left hand :dry:

And I think it might have been only on the left side.

Yamaha on the right hand side.ask me how I know.bj

I'll bite....how do you know?

And the right hand I remembered, just couldn't remember 8 or 10mm. Glad to have ya'll confirm it for me though.

You'd think that left hand crap would be British. They used to do alot of stuff like that on the early bikes.
