    Trouble shifting when warm -

    Hello all:

    I'm new to the GS world after buying an '85 GS700e a couple of months ago with ~25k miles. Enjoying this bike very much but having a weird shifting problem I can't figure out.

    When the bike warms up to about as hot as its going to run (after 15 minutes give or take), it regularly finds a false neutral shifting up between 3 and 4, and 4 and 5. And downshifting is constantly a challenge and it gets into false neutral frequently when hot. And then, at times, it will shift perfectly fine up and down....but more often than not it finds those false neutrals and I have to double-clutch or just keep kicking the shifter pretty hard to get it in gear.

    When the bike is cold, it doesn't display any of this behavior.

    I've replaced the clutch springs with OEM and that has helped, maybe a little, and I've adjusted the clutch cable per the service manual. I have changed the the oil, and put on a new chain. I've ridden it about 400 miles so I am getting more used to it but maybe I need to make changes to my shifting approach.

    Prior to me digging deep into the transmission I thought I'd reach out, especially considering the temperature consideration.

    All thoughts welcome.

    I moved the gear shift lever down a position just to change the physics of my foot, and took half the free play out of the clutch cable, and the upshift false neutral problem was totally resolved. Including between 4 and 5 which was constantly a problem.

    Down shift false neutrals improved significantly, but are still occasional enough to be normal. Other times I shift down easily and effortlessly.

    Hopefully this means its simply a clutch/shift behavior learning curve rather than a serious problem inside the transmission.

      If the clutch plates are a little warped and dragging that will also cause the symptoms you mention. I struggled with a similar issue and after replacing the friction plates and steel's the transmission shifted like butter.

        I agree with Ed.
        Had a similar shifting issue on an '83 Kat and it was warped/worn clutch plates. Too much time at the dragstrip.
        Some good info in this old thread.
