    Shifter Locked Up, Transmission Problems?

    I was hooking up the wiring on my 78 750 rebuild. The bike is in neutral and the shifter is frozen, will not shift up or down. I took off the cover to see if something was binding it up and I don't see anything. I have had the motor out to clean and paint it.

    The rear wheel turns fine and the bike turns over fine with the kickstarter. Also, I had the clutch hooked up and the cable is a problem since it is not really long enough, but the clutch pulled in okay, seemed to engage and disengage. Any ideas?

    A little more info is needed,
    #1 when you try to shift the transmission does the shifter move at all? and if it does , does it feel like it has spring tension on it to return the shifter to center?
    #2 Did it work before you tore it down, was the bike up and running before hand?
    #3 Do you have a chain on it and have you tried rocking it as you try shifting it? also try starting or turning the motor over,on the bike then try and shift it .

      1. Feels like it is welded on the bike, no movement at all. Didn't want to force anything.
      2. The bike ran and shifted before I tore it down.
      3. It does have a chain and the rear wheel turns freely and the kickstarter will turn over the motor without any noise, grinding, or extra effort. It is stuck in neutral right now. I put pressure on the shifter as I pushed on the kickstarter and still stuck. The starter is not hooked up, still have a wiring issue there. It did work before.

        Try loosening the sprocket cover. If it's not perfectly square to the engine it will cause the gear change shaft to bind - hence no gears.

          I took it off, thought about that. I was praying that was the problem.

            When you had the motor out did you by chance bend the shifter shaft or drop the motor accidentally?If that happened it may have jarred something in the transmission. You could also pull the clutch cover and the clutch basket , behind it you will see where the shaft comes through from the left side , make sure that nothing is wedging it there and that the detente spring and plunger are still working.

              My mind is going to the prospect of pulling out the clutch. Several new things (for me at least) come up. If I tear down the clutch, will I want to replace anything, what and how do I inspect. Then the expense of new oil and possibly a new cover gasket. This is sounding like my lucky day.

              I didn't drop or jar the motor while it was out. Did turn it on its' side to take it out of the frame, but not the shifter side.

                This is not a biggie. Chances are you would want to do this eventually for routine maintenance. Clutch springs are likely out of spec.

                You can re-use the oil and if you're careful the gasket.

                Yank it all off and find out what's going on in there. Post some snaps and someone will know what to do next. It's got to be simple......

                    Now With Pictures

                    I have finally taken off the clutch case and I really don't see anything that is apparent to me why the shifter does not move. remember that the shifter is stuck in neutral, motor turns over fine with the kickstand and the rear wheel turns fine.

                    Here are a couple of pictures of inside the case.






                    Anyone have an idea?

                      the problem you have is seen in the second pic. you see the fork part on the end of the shift shaft with the teeth at the end. there is a spring in behind it. the 2 legs of the spring should sit either side of the little stub shaft, just visible above the top leg of the spring.
                      hope that is clear enough!

                        We did the same thing to my bike. You have to pull the hub to fix it IIRC.

                          yep, you do have to pull the clutch, to line up the teeth on the 2 quadrants and locate the spring properly in behind
