    Also, anyone know what thread the grease nipple is? I need to put a 45 in.

    My grease nipple is at the bottom front of the rear shock. It might have a black cap over it... Mine doesn't. Sorry no pics. Check your manual as it should show it.

    Look at the bottom of your shock.There should be a round adjustment knob there.

    You mean the very bottom? I've looked at shocks on eBay and can't see it either

    It has the little grooves in it so you can grip it and turn it.
    If you visualize looking up as if you were laying under the bike, turning it clockwise closes it and stiffens rebound resisting the spring from returning the bike up from compression.
    If you turn it counterclockwise you are opening it or softening the resistance to the spring to return the bike up from compression.

    Rebound on the bottom, compression on the top, the nipple is on the pivot, not the shock, sometimes takes grease hard, warm it GENTLY with a heat gun, hair dryer....

    The book settings for suspension are nonsense.

    Count the clicks or turns and set it in the middle.
    Then ride the bike and start adjusting harder or softer till its how you want it.
    If you can't get it where you want it, then it needs to be revalved internally.
    Before anything though make sure your spring preload is correct by checking your sag numbers.

    It's stealthy.
    The only way I can adjust it is to lay on my back on the ground and look up at it(when it's on the mc.

    As for setting the sag, another PIA to do with the shock on the machine.
    Easier to remove it, the axle wrench has a spanner built in for the spring adjuster collar.
