    i have a 1988 hawk gt. I had it on the center stand and noticed when i
    rev the engine in neutral, the back wheel starts to turn, so I tryed
    adjusting it, but looks like its far as it can go... I've done clutches
    on cars many times, but when I looked at a site to buy ( a clutch ) for
    my bike, there is about 30 parts listed. where as with a car you just do
    pressure plate disc and t/o bearing. what would be typical parts needed
    to do a clutch... it has 12,000 miles on it. Thanks in advance,

  2. There is NOTHING wrong with the clutch. Your motorcycle has a constant
    mesh gearbox. All ten gears are always meshed with their opposite gear
    even when the gearbox is in neutral. There are NO bearings inside the
    free-wheeling gears. The free-wheeling gears spin on the shafts on a
    steel-to-steel mating surface. Fortunately, there is oil on the
    mainshaft and countershaft. But oil has viscous drag. It's a little
    sticky. In your transmission, the oil is sticky enough to make the
    freewheeling gears on the mainshaft turn the pinion gears on the
    countershaft. Viscous oil drag turns gears on the countershaft, even
    though the gearbox is in neutral. The countershaft turns the
    countershaft sprocket. The countershaft sprocket pulls the chain, the
    rear wheel spins when the engine idles. Especially when the oil is
    cold. If you want the rear wheel to stop spinning, put your shoe
    against it, it will stop. Pull your shoe away, the spinning will start
    again.

    DO NOT ATTEMPT TO USE THIS UNINTENTIONAL WHEEL ROTATION TO LUBE YOUR
    CHAIN!!!!

    You'll cut your fingers off...

    Why would his fingers be in danger if he's lubricating the
    chain? They shouldn't be in a position to be in danger.

  4. If somebody knows how to lube a chain properly, they are squirting the
    chain lube onto the edges of the rollers ON THE BOTTOM RUN OF CHAIN,
    not the top run, while turning the rear wheel BACKWARDS, so the chain
    is moving AWAY from the rear sprocket.

    If an idiot was squirting chain lube on the bottom run of chain with
    the engine running, the chain could catch his shirtsleeve or hand and
    drag his fingers into the sharp sprocket teeth...

    A guy I now was doing exactly that when he amputated the first joint of
    his index finger. He wrapped the severed joint in a wet rag and went to
    the emergency room to ask if they could do anything for him. So he went
    around the rest of his life with the first joint of his nose-picking
    finger bent off at an angle...

  6. Oil drag.

    Now adjust your clutch properly before you break it.

  7. Now please explain why the exact same thing happens when the motorbike
    has a DRY clutch...

    If "an idiot" puts his fingers or loose clothing within reach,
    I suppose he gets what he deserves.
    I lubricate my chain by spraying chain oil inside the bottom
    run, using the plastic tube that comes with the chain oil. With the
    engine idling, and the trans in high gear. I know better than to get
    my fingers that close.
