    With Earl's history of parachute drops, let's hope he doesn't develop a jet stream :twisted:


    If the luncheon chiles have not yet worn off, this is the season, at least in my area, for Highland festivals.....perhaps we could put you in a Scottish Caber dance.....but stay away from the Highland fling.

    Oh' yes, the vibes.....have you considered a jazz group??

    Alternatively, I would pull the carbs off and look at the butterflies ...no not the tummy ones, the carb ones (but bee really careful, especially after those chiles). I've had a similar problem and finally pulled them off a couple of days ago....#3 was out of synch and pulling too hard no matter what I did with the adjuster screws and synch tool.

    Thought for sure it was a needle valve not setting properly, but with the carb bank sitting on the pad in front of me I could see #3 butterfly valve was just a bit off. I considered replacing the butterfly (I have a spare set of carbs) but instead opened all the screws. Backed off the idle screw until it was free from contact, then adjusted # 4 screw until 3 butterfly was closed.

    Vibration is gone, and engine purrs nicely, but I have lost most of the power. Adjusting the choke setting at mid-range makes it pull better, but there simply is no top end at all. Definitely a mixture problem.

    I just pulled out the air filter and its partly gone, so I have too much air. An OEM part was on back order for months, and a mechanic made one for me, a few months ago, but it has partly disentegrated.

    Off to get the stuff right now. and will fake my own.

    Good luck with yours.

      Follow-up
      The new filter material worked. (Not what I wanted, but it is better than nothing) Mixture now turned back to lean and got all the rpm's back. Smmooooth as kitten's purr at the low end, growwls at the upper.

      No white horses nearby, but I heard there was a diesel Chevette that's new in town...also a shaft drive and about the same vintage as my GS. Gonna search it out and have me some serious competition.....

      Earl: Hope you have the same luck.

        Alright guys, I give! I bought a 5 gal gas can tonight and I'm gonna' pull the tank and drain it on Monday. Will any small inline fuel filter work for my purposes, or is there a specific one that I should get? Hopefully there's no rust in the tank and everything is just gunked up from the bike being 25 years old. Anyway, I'll do everything that you told me, including cleaning up the fuel valve.

        About the carbs, I'm a little leery of tearing them apart, will a cleaning spray solve the problem or should I take it all apart and dip them? I have the Clymer manual for the bike, but I haven't had time to read through the carb section yet.

        Thanks again for all of your help!

          So, you're a little Leery, are ye? Apologies to ye, lad. How could I have missed the Irish brogue??


          First....the tank.....get a large clean container, such as a plastic tub, and have it ready for when you swish the tank. I do understand the confusion you face, but you don't have to look swish in the Irish manner, you only need to swirl a pint of gas around the tank before you dump it in the container.


          If the dumped gas has a lot of rust, you may have your problem fully identified.
          If it is rust-free (and who charges for rust anyway?? I am sure it is free in most areas) then you have a petcock problem.

            Well Ron, oddly, I did. Spent the day retuning the carbs to a little richer setup. (I seem to get a bit more power, its smoother, and it revs nicer) Anyway, was out for a test ride on the interstate, checking out the "roll on" at 85 mph or so and had noticed the unusual vibration was still there around 60. Well, turns out it was a baffle in the right muffler that had worked loose and at a particular rpm and resonance, it vibrated. 85 mph apparently was enough to blow it completely loose and heh heh heh...no more vibration. Oh yeah, I'm happy with the carbs now. Priscilla thinks she's an 1150 now instead of a 750. :-) I figure my gas milage will drop about 5 mpg, but I dont care. She runs faster and cooler now.

              Scot-Irish and German actually.

              A pint, eh? Aye, seems I have a measure of a pint 'round here somewhere

              I'll let you know how it turns out, thanks!

                My apology...forgot to address that part of your query in a previous post.

                You can use whichever in-line filter fits in the space you have on your bike. It does not need to be big or expensive. (probably $2 to $3) Just be careful to get one with the right diameter inlet/outlet. The inside diameter should be the same as your gas line tubing size. Also..look at the outside of the filter before installing it. Some are directional and are marked in - out or have arrows. Still others are non-directional and can be mounted/used either way.

                Change the filter at the beginning of every season.

                  About the filter. Try to find one that will filter at 40 microns. Thats will keep everything but the smallest junk out of the carbs.
