rb21, would you please check the hardness of one of those shims, as Mike and others have found soft shims in other manufacturers' kits, and report back to us your findings. Thanks.

Sure can - I also have a kit of hot cam shims from an old dirt bike that I can use to compare. I'll see if I can do this tonight - if not I'll do it this weekend.

I would say that my non scientific test results should be considered Inconclusive. I used a set of hobby files, because thats all i have, on the edge of each shim with a fair amount of pressure and don't really see a difference between the two. I'll try to get a good picture later once i find our good camera - cell phone camera is not doing it. I am assuming that jewellers files as mentioned by Mike earlier may have a bit more bite and be a better tool for the test. Probably still a bit vague - a rockwell hardness test would most likely be something that would give us the real usable info. I don't have access to that kind of equipment.
Any basic machine shop should. Engine rebuilder etc... Is there one near you?
That is of course, if you're willing to spend that kind of time on it. Sorry for assuming
Let me look around - if its not expensive and somewhat convenient I'll do it just for kicks and let you all know.

rb21, sounds like they are the real deal if they didn't mar on you unscientific scratch test! I had read the Hot Cams shims kit were softer than OEM & H-D shims, and shouldn't be used in the EBR.
Turns out a friend of mine has the proper equipment to test hardness where he works. Should be able to post results next week.
The results are in. I randomly pulled one shim from each kit and sent it to the a lab at my buddies office. The pic below has the results. Looks to me that they are very similar. They did three spots on each shim using the Rockwell A and C test methods. I don't know the details of each test method- just have the results.

And that concludes our show, have a good night
Thank you rb21! Concrete evidence is so rare these days:) I'll be getting a shim kit for my upcoming adjustment (1000 more miles won't take long).
