Valve Shim

Who here knows about valve shims, how to make changes and what purpose they serve on our scooters.

I found this http://cgi.ebay.com/ebaymotors/HONDA-FSC600-SILVERWING-HOTCAMS-HOT-CAMS-VALVE-SHIM-KIT-/320707858371

I have no idea because I am a new rider and I am not mechanically inclined so I am trying to learn about everything and do as much as I can at home with my own tools.

Does shim replacement or adjustment do anything for performance and increased hp and tq?

I am interested in doing any kind of performance mods for the silverwing including cams if someone makes performance cams for us. Thanks for looking and I can't wait to hear from any of you.

Well I understand that my bike has over 26,000 miles and needs a valve adjustment more than likely so I was wondering if I need something like the product I showed in the link above to provide to my mechanic when the time comes to adjust the valves. Is it needed?

And if so, is there any performance gains with this maintenance priority?

I am not trying to do this all myself but I am trying to learn why certain things are needed and make sure that I don't leave any stone un-turned in my quest for more power and keeping my machine running in the best possible condition for many many miles to come.

When I adjusted my valves, I simply brought the shim with me to the mechanic's shop and he pulled out a generic set of shims for that diameter. The process was an exchange, not purchasing something new. The shims don't wear down. I believe it is the valve stem that stretches over time, or the valves themselves that wear to cause the need for an adjustment.
