    Great news!
    The bike started up today. I never even thought about that stupi
    sidestand switch until Bryan mentioned it. SO I put it up and had t
    fidget with it to get it to start. Now the bike does start, but jump
    while doing so. Also, the idle is stuck at about 4000 rpms, so mayb
    that is a choke cable. All of that comes later. I still have the sam
    problem with the clutch. It is really hard to pull in (my hand i
    throbbing sore from about a 6 minute ride) and it is still stuck i
    first gear. I cannot shift up or down, the lever is tight. Should I g
    through the same procedures ripping out the clutch and all or shuold
    see if I can fix it while riding? Any suggestions on how to fix thi
    would be great :)

    Thanks alot guys...I'm smiling ear-to-ear

  2. Yes, there is a lot of slop in a motorcycle drive train. There are
    shock absorbing springs in the clutch basket, there is extra room in
    the slots in the gears so the dogs can slide into them, there is slack
    in the chain and there is a rubber damper in the rear wheel. All of
    this slop means the rear wheel will jerk like crazy if you start the
    bike in gear.
    It's possible that the previous owner fooled around with the idle
    mixture screws, thinking that all they do is adjust idle mixture.
    Problem is, if they are opened too far, the idle speed screw has to be
    adjusted further open to compensate, and that uncovers the transition
    ports next to the throttle butterflies. When the engine starts, it
    races at high RPM.
    You might as well remove all the clutch plates and check to see if any
    of them are bent. A sheet of glass is usually flat enough to lay the
    plates on to check for straightness.
    The shifter drum is probably stuck, due to those shifter pawls I
    mentioned, or the shifter forks are jammed. The only thing you can do
    without going removing the clutch is to rock the rear wheel back and
    forth and work the shifter lever until the shifter drum or forks free
    up.

    Once you get the clutch basket out of the way, you'll be able to see
    how the sector gear mesh together to turn the shifter pawl. Make sure
    the sector gears are aligned according to your repair manual.
