    Seized engine?

    I drove my 77 gs750B last fall. On the highway the bike gave out, was acting like it was about to sputter and die, then made a high pitched sound like "fzzzzzzzzzzzzzzzzzz" and completely died. The kickstart doesen't want to move when in nuetral, but when I pop off the point cover I can move the shaft with a wrench up to a certain point. Any ideas what could be happening? Can I provide any other details?

    What happens when you pull the clutch in, and try to rotate the crank? Might be something seized in the transmission.

      Moves freely in nuetral with clutch pulled in, but won't crank. Kickstart seems to move a little to easy, like there's not a lot of resistance. Makes a "thunk" sounds when I try to turn her over

          Kick starter will always move w/ very little resistance with clutch in.

                  Cam chain adjuster stopped working and your chain jumped

                  Pull the valve cover, see if you have a chain, check the cam timing

                    Is this the same bike that you ran out of oil?

                      apparently it still had oil in it.

                            Drain your oil and and open up your oil filter and see if you find any metal pieces in it. Take the valve cover off as mentioned and see what the cam chain is like.

                              I'd start with the valve cover
