    stuck clutch

    for lack of a better term, as I never much understand clutches.
    Sadly, my XS sits in the garage. Always on the ST. Every now and then I'll start it for a couple minutes just to get things moving a bit. Doesn't usually occur to me to go through the gears however.
    Anyway, I was gonna ride the XS down the street today before a winter in the garage. Started pretty well (in neutral) engine gradually smoothed out to an ok idle and sounded fine. Went to shift and it immediately conks out. Lurches when trying to start with the clutch pulled in, so can only start it in neutral.
    I should know the answer to this, but, what is my clutch doing, or, not doing?

    stuck clutch

    I have had similar issues with misc. machines.
    The clutch plates will "stick"together after sitting for a while .
    I think the oil drains out of them.
    I sometimes will get the bike rolling and ease into gear,
    Then pull the clutch in a time or two while rolling and they free up .
    Another way is to rock the bike back and forth (not running)
    while pulling the clutch..in and out.
    Hope that info helps

      Roll it up against something solid. Put it in neutral. Pull the clutch handle. Hit the starter.

        Best remedy I found was with the bike not running, put it into gear and pull the clutch in and rock the bike back and forward a few times. Sit on the bike while trying this so you dont drop it. It should only take a few rocks to free up the plates. Why challenge the starter/battery any more than you have eh?

          Put the bike up on the centerstand, start it in second gear. Then give it some throttle, pull in the clutch, and stab the rear brake. Repeat until the clutch frees up. Then ride it at least ten miles, getting the bike to full operating temp to get the oil back into the clutch....

          Much easier on the starter this way.

            Just an FYI Dean........since you don't ride it much, add couple ounces of the blueStarTron fuel treatment to the gas. Do NOT use Stabil! Even the new blue Stabil is not near as good as what I first mentioned. (Gonna put a new thread as to what Scott(3Phase) and I just went thru on my Venturer with the never expected gas here on the western slope of Colo. Was some ugly stuff that tottally plugged carbs solid.).

                I use the blue StarTron fuel treatment for my snowmobile and have had good success with it. It does mention that it is not a stabilizer but an ethanol treatment which is apparently different from each other. Not sure it matters because it keeps the ethanol from separating which causes more problems than stale gas.

                  Haven't had a chance to 'unstick' the clutch yet. Will give each suggestion a try shortly. Thanks guys.

                  Regarding storage. I've been draining the tank (after running Seafoam usually, or Startron or Stabil) and just bringing it in the house for a number of winters now. Motor is run till it conks out. I don't think I've ever needed to drain the bowls.
                  My lawn mower has had a pretty steady diet of drained gas!

                    +1, On my 56 XS650s the clutches were always stuck to some degree, they had kick starters so before starting I would but them in gear and kick until the clutch came free. Then start and warm in neutral when idling/reving well, pop it in gear and go. Very little crunch when put into gear, the clutch was already free.
                    The 11 has no kicker ( except my 79 I bought new, added a 750 kicker to it )
                    since my 81s don't have ability to add kickers I start in neutral, warm and shut down, put in gear and grab the front brake, start and go.

                      Mine did the same, even with brand new clutch plates and springs. I found that putting the bike into neutral and running the engine for five minutes, pulling in the clutch lever and letting it out repeatedly, usually did the trick.I think that it's possibly a partial vacuum on the plates, rather than them drying out, actually. They sit squashed together for a while and drive out most of the oil that's on the friction plates but there's enough oil left around the contact points to keep them stuck together. Well, that's my theory, based on taking the plates the first time the clutch locked up. After that, I just ran it as per the above......bit of a clunk after engaging first gear and that was it sorted, every time.

                        All unstuck and moving down the road nicely. Thanks for all the suggestions. Still a beast and not bad lookin' either.
