    Carbs..running fast!

    Decided to clean my carbs on my GS550 1979 (CV style)

    I have cleaned as per the guides on here - broken down every bit.

    I thought the bike was running a tad rich, so I drop the needle, now on the last notce. Bike is jetted with pods, 4 into 1

    Performance of the bike is amazing. Very quick. But I can't get the bike to idle, after a while it settles down if the undo the throttle cable, i rev, then the bike returns to 4000 rpm.

    I have checked for air leaks.

    Could this be because the bike is running to rich? I just can't reach the screws.

    any ideas????

    Had this set up perfectly before :-(

    Undo throttle? Maybe a slide or cable is sticking.

          Several threads and numerous posts here on the "hanging" idle issue. Search the forum with "hanging idle" and you should get some ideas on what to check. Some kind of a vacuum leak seems to be the most common suspect. Good luck.

            Did you change the intake boot O-rings?
