    Shift rod(shaft) is loose. Will it hurt anything?

    I have a 79 gs550 and Ive had a clanking noise for awhile now when i hit bumps whilst decelerating. Ive tightened every bolt twice and checked everything that moves. It is an internal sound though.

    Id all but given up looking since it had not caused any ill effects,until i pulled the front sprocket off to check the sprocket nut. I noticed the shift shaft would pull out about 1/8 inch or so. It will also travel front to back but not up and down. Before i pull the clutch cover on the other side,does anyone have suggestiond for what is wrong? Could this be the cause of my noise? Ive had a few problems with the bike shifting but nothing the wrong shoe couldnt cause. Is it held in on the clutch side the same way as the sprocket side using a clip of some sort? Thanks in advance for any help.

    is there any slack in the shaft going with the rotation of shifting? It should be centered and resist rotation. In/out play can't really be good, but it isn't necessarily bad. Any side/side play is bad and typically indicates a worn shaft, seal, channel or a combination there of. Any slack in the shifter can cause it to rattle the gear should you hit a bump or something.

      There should be a clip on that side keeping the shaft from sliding in and out. Maybe the clip came off the notch or gone?

        Agreed on both of the responses. You may, if you have a clutch side gasket to replace it with, check the shifter fork/cam, whatever you want to call it, to see that its not coming to far out of alignment. I have never noticed play in any of mine, so its something you'll want to attend to eventually, if not sooner.

          mine (an 850) goes in an out about that much too (2mm or so)
          when i had the engine apart i couldnt see anything worn that would be causing it so atributed it to the design
          given that that rod is a well lubricated part and if the in/out movement you're describing is all there is to it, i dont really see how it would give you a "rattle" that you hear
