The usual solution seems to be to replace the bumpers--they harden over time and tend to make that sound when the stop hits the bumper.

Did you have a look at the rotor bumpers, too?

Don't forget to check out the linkages. I often get clacking when the grease dries out of the old ball joints. Are you running the rotors in plenty of oil? When I first got my rotary valve Yamaha the horn players in orchestra advised me to have them "swim in oil".

How did you decide the alignment is off? And did oil/grease fix the clacking?

That's amazing -- I had no idea MC Escher was a brass player!

On my horn, there's a line that should line up if it's in alignment.

And yes it did after a while of playing.
