    For those that do your own valve adjustment

    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.

    Interesting. I've been using the Hot Cams kit for years now. I do probably 4 valve adjustments a year (2 race bikes), and I've never noticed wear beyond what the factory shims also show -- the bit of polishing that happens in the center. I also re-use shims since you only get a few of each size -- so I'll bet a couple of these shims have seen service duty on both intake and exhaust, over quite a period of high-rpm use.

    I wonder if you got one of a bad run of kits or something.

    Same here, did 4 valve adjustment/checks on my 1125, never really had any issues with the Hot Cams kit.

    Similarly, although use Hot Cams - no problems.
    Moreover - from V-Rod also sell kits Hot Cams:

    If you can sand them thinner with sand paper, they are too soft...period.
    I like my adjustments to last a while longer than a few months..! I drive my bike daily, 22,000 to 24,000 a year. I need it to last as it was designed without working on it all the time..!

    Here we go again, details. Best to pay attention to the details.

    As I said, your money your engine..!

    Me, I'll follow Rotax's (Buell/EBR's, even Harley's) lead, and not buy the cheapest parts available.

    I also travel a lot on my EBR - this is my only bike. And this is my everyday bike. My average mileage - 3000 km per month.
    Can you give a link to the correct shims?
    Or you are using the original EBR shims (F2200.1B6 etc)?

    So the V-Rod shims are the same as the 1125 & 1190?
