Rotary Valve Noise

I have a Yamaha 641 (4 rotary valves). I love the horn, so please no bashing.

The first valve (and somewhat less noticably on the second valve) there is noise at the "end" of the valve "stroke." I mean when the valve is all the way in either direction and it hits the rubber stops. This did not occur when the horn was new (just less than a year now) and doesn't occur on the 3rd and 4th valves (maybe because they are less used?).

Any suggestions, advise or information would be appreciated.
