    1982 GS550M running bad(video link)

    I've recently bought a Katana that has been unused since 2001.
    At first startup the carbs flooded and the engine wouldn't run properly. I then dissasembled the carbs and did a thorough clean, set the floats to 22mm and tested the diaphragmes. I also changed the spark plugs and checked the intake boots for leaks. Now I can get it to idle fine but when the throttle is engaged it runs bad. I've uploaded a video on youtube so you can see and hear what the problem is.

    Sounds like muck in the carbs.

    Did you clean them like this?

      What air filter or airbox are you running?

            Put the airbox back on it will run fine.

              This.

              The airbox makes all the difference. You'll have to remove the carbs to put the airbox back in first.

                That's just how CV carbs run with no airbox.

                  You were right. It runs fine now.
