    I had the same problem on two of my then new bikes,74 GT 750 and 78 GS 1000. On both I found a place on the carb rack to put a small bracket and hardware store spring configured to open the throttle. I sized the spring so It would assist opening and counter some of the factory stiffness. A couple of adjustments to spring length were necessary to get it right but when I did the spring pressure was cut drastically and made them very comfortable to ride. There was still enough so the throttle would close completly when I let off.My current 83 gs 1100e does'nt really bother me so it's ok as is.

      I feel your pain. My 77 GS750 had a tough throttle. I used a cramp buster. It helped. Some people hate them, but it made the bike ridable for me. You can pick them up for like $10. So it's a pretty cheap experiment.

      I don't seem to have this issue on my newer bikes.

        Same here. '79 GS1000. There is no perfect spring.
        And on the seventh day,after resting from all that he had done,God went for a ride on his GS!
        Upon seeing that it was good, he went out again on his ZX14! But just a little bit faster!

          METAL COAT HANGER. Make an "S" hook with one end closed to hook the spring to and an open end that goes over the stud on the rack. Experiment to be sure the throttle linkage returns reliably. Less stretch means less pull at the grip.

          Ive done this and have had no issues....

          NEVER SNEAK UP ON A SLEEPING DOG..NOT EVEN YOUR OWN.


          I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.
