I'm in the middle of my valve job right now. I tried to call a Harley dealer the other day to get individual shims and their parts department convinced me that valve shims did not exist, and I had to be thinking of valve guides.
After that conversation I went ahead and bought the Hot Cams shim set. All of the ones I will need measured within .015mm of their spec'd size, most were less than .005mm off. Not bad for $60, especially considering their size divisions are .05mm and now I have enough of these things to take care of both of my KTMs.
