    Major Starting issues 81 GS650GLX

    Hello GS Pro's. I just bought an 81 GS650GLX that hadn't been started in a little over a year. I did the basic fluid drain/change that would be normal for a neglected bike. I also cleaned up the carbs and replaced the intake pipes (the originals had some leaks) I've been attempting to fire up the engine and have had very little luck. Today I disengaged the throttle cable from the carb and the engine started right up. (short cable, maybe?) however, the engine ran great for about 10-15 seconds, then it started climbing RPM's until I had to kill it. It jumped quick too.

    This confuses me as the throttle wasn't even hooked up. Any advice? What should I be looking for?

    Thanks. More to come.

      Get the o-rings and also order a new cable.There only about 15 bucks.Make sure your choke is working properly and you have set the idle adjustment when warmed up.

        What they said, and did you completely disassemble the carbs and dip them, or just spray some cleaner into them?

          Got the O-rings

          Yep, I definitely put new o-rings behind the intake pipes. The choke cable is busted. I've been pulling the choke by hand. Probably a good place to start. I'll fix that problem and see how it goes, although I don't anticipate the choke will be the problem since I've been engaging it by hand. I didn't dip the carb. I simply fixed the inherent problems, i.e. the intake pipes and the #1 bowl missing a plug bolt. It's air tight now, but I'm thinking the problem has to be in the carb/fuel. The bowls fill up great. I've goosed the cylinders w/some starting fluid to check er out after I checked for compression (no meter, just feeling for pressure) I'll replace the choke though, we'll see how that goes.

          I'm hellbent on getting this beast running. Wish me luck.

              Get a new choke cable too.Are you sure your letting it warm up first?With my choke half on the bike will stay at about 2000 rpm and then start climbing when it starts to warm up.When it starts to climb try adjusting your idle screw down till you get to 1000 or 1000 rpm's and see if it holds.I think you problem is no choke cable.these bikes are cold blooded and take at least 2 minutes to warm up in the summer.I really depend on my choke.I dont even touch the throttle till it warms up and idles without the choke,(about 2 minutes after starting).

                Clymer repair manual

                So yesterday my Clymer repair manual showed up at my door. I unwrapped the packaging, set it next to my bike and attempted to start er' up. Presto, fired right up. Those Clymer manual's are magic.

                Actually, I think it may have been the fact that I had charged the battery for a bit, and removed the throttle cable. The bike ran okay for about a minute and then died out. After monkeying with the throttle cable (letting it out as far as possible), I re-attached it and started it again. Started right up. After I let it run for about a minute, I tried to throttle it a bit and it died out and wouldn't start again.

                Very small victory's, but I think I'm on my way.

                No choke ever used during this process.

                  You need the choke and also do you have the air box lid on and filter in? If not, dont expect it to stay running.You have to have the airbox and filter in or it will die as soon as you try to give it gas.Your almost there! at least it starts,that's progress in the right direction!
