Pretty much any dealer that sells and repairs motocross bikes should have these on their shelves.I did buy a complete kit from hotcams for same reasons mentioned above...so i have them and i don't have to make a few trips.

 

that retarded dealer that had my bike for a long time didnt carry valve shims in stock... that pissed me off... thats why i bought the shim kit.. so i can do it my self and have everything i need to do it and get it done.

 

When I asked my dealer what they did for bikes they were working on he said they had a selection of shims in the back but he said they don't sell from their own mechanic's supply and order yours from Kawasaki. I thought that was pretty lame, to say the least.
