    sc question

    what is the point behind shimming the washers? when they wear do you run out of thread for the nut to supply sufficient pressure

    You don't run out of nut, but this piece bottoms out. To put more tension on the clutch pack you need shims.

    They will have an initial break in then you will loose a couple hundred rpms.
    2-6 hours depending on setup and how hard you ride. The 25mph wind chop speeds up the process. Then we are trying to setup around 12 ft lbs. They will go longer the 2nd round. Then turn them over on the third run.

    stan... is this with Les' metal washers you are finding this, or consistently across the board with any metal washer?

    TennesseeRXP had 50 + hours on a test set of metal washers before they needed shimming. Stan runs closed course. Big difference between that and rec riding.

    I ran my metal washers for like 4 hours and gradually lost rpms over 30 mins and then down to 6100 rpm Had to bring machine in and since then over 15 hours no slippage and I've been running HARD.
