Hello and welcome

You can purchase them from any skidoo dealer or an online parts dealer like     
partspitstop.com
Cheapcycleparts.com

There is a valve shim calculator under the tools and tips  area on this site, where you enter what shim size you have, what the clearance is at with that shim, and what clearance you're shooting for. It'll spit out what size you need

There's a chance you might have less than zero valve clearance if it's starting real hard so make sure you check on that

It may take some trial and error to find which shims will work best for each valve. If you have ATV workshops or powersports stores, they usually have a big box of shims they can sell you if they're nice. I have one around me that sells them for about $4 each.

step 1 measure your valve clearance on all four valves, write the numbers down do not remove shims at this time

step 2 clearance should be .004 to .006     if you have .002 clearance you need a shim .003 smaller to get you .
          .005 clearance take shim out and measure it with a micrometer you need to remove cams measure 
          all four shims.   write  the numbers down  you may be able to reuse a shim in a different location

          if you have no clearance start with a shim .006-.007 smaller  install cams  and measure again

         this should get you close
