Just a heads up. I went to three shops today to buy one valve shim for my RX. Two of the shops use the "Hot Cams" shims.
If you want the adjustment to stay in place for the longest period of time...DO NOT use the Hot Cams shims, as they lack the proper heat treatment to make them hard enough to last.
If you can remove surface metal with a file or sand paper...they are NOT hard enough.
Back when I was driving my 1125CR every day, at one adjustment period, all eight shims needed to be replaced. I bought a Hot Cams kit. One particular valve needed an in-between size. Out of frustration, I got out a fresh piece of 600 grit sand paper...NOT expecting anything to happen. What do I see...material coming off the shim..! I was able to remove .002" without problem.
I took one of the Rotax (branded) shims, 600 grit paper did nothing. 400 grit sand paper did nothing... I tried a couple more Hot Cams shims thinking maybe someone made a mistake in the heat treatment. Nope, three different thickness shims I was able to remove material.
I ended up at a Harley buying a V-Rod shim today. I checked...it's nice and hard.
Your money, your engine, this is just a heads-up if you want your adjustment to last more than a coupla thousand miles.
