    I have got my GS 850 running now but when she;s just stood with rev's at between 1000/1500 she's making a popping sound from the exhaust is this something to do with the mixer screw for air/fuel. Cheers Paul

    So it makes this popping sound at high idle and then goes away as revs increase? likely running too lean,so could be the idle mixture setting.

      Ok thanks for the reply so quick, what do you mean by lean is that not enough fuel or to much fuel

          Yes on the gaskets..if theres a leak or pinholes in the pipes they suck in fresh oxygenated air and the residual fuel gasses then exploded in the pipes and make popping sounds.

          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.

            This is pretty funny, each response has been made by someone with their name as their Avatar, even the original post....I guess I'm bored.

              What carbs have you got on there Paul - CVs or VMs? I seem to remember you did a carb rebuild - if so did you follow the appropriate tutorial to the letter and make sure everything was 100% cleaned?

                What year is your 850?

                The '79s had different carbs than later years and would require different adjustments.
