    Without knowing what your current shims are, it would be pretty hard to predict what shims you might want to buy. Hence the idea of purchasing the entire hotcams shim kit.

    Valve clearances typically lessen over time, so if it was recorded what shims were used on your last valve adjustment, you could make sure you had the 2 .050 increments below your current shims and you almost certainly would be good. (though often you won't need any adjustment, and can reuse current shims on different valves as needed)

    DEZRACER - Ive done my valves and know what the shim sizes are. I bought the "whole 8" next sizes, 0.025mm down so that next check Im ready to go. Might need them - might not. But for the cost vs convenience measure they were a bargain and will keep the 9fiddy hummin through the 30km service, so that takes me to 40km before I have to worry about it again.:clap

    I bought the Hot Cams box of 84 shims yesterday. $69.95 plus $7.95 shipping. Many thanks to this thread for turning me on to that alternative. Our local Harley dealer parts guy was very helpful, but he said that he could only order the V-rod shims priced at about $3 each, in packs of 5, so the Hot Cams box seems like the best way to go. Will be much easier to re-do, if I find I've goofed on sizing after reassembly.

    Got an 8mm, 1.25 thread-pitch bolt, 100 mm long at Ace Hardware to use as the TDC crank lock for $.98.

    Hope to do my valve adjustment in the next month or so.

    Along with other people on this forum i`ve been using the 9.48mm hotcam shims in my 950,at the time the 10mm kit didnt exist.
    I doubt wether i will buy the new kit to replace my current hotcam shim set.cheers

    The KTM shims should be measured they are often not exactly what is stamped. Look at the positive side there are partial steps.:clap

    People have used them, just read a few posts before yours. But the DRZ uses 9.48 mm the KTM 950 uses 10.0 mm. So can you? Yes. Would I use them in my bike? No. I don't like the idea of using the wrong sized part in, to me something that is very important. Call it piece of mind. A new Hotcams kit is only $70.

    How do you decide when using a feeler gauge how tight is right for a good measurement?

    It's all relative.:D

    My preference is to get some resistance on the feeler gauge when withdrawing it. About 1/6 of a turn is about the difference between shim sizes. Going from memory . . . Anyone correct me on anything. A lil pui!:lol3
