    Vacuum leak possibly at reed block or intake boot, could also be blocked pilot circuit but too lean for sure. Does the air screw have an affect?

    Video004 - 2,5 turn air screw
    Video005 - 2 turn air screw
    I tried 1 turn air screw, but I had same problem. When he was cold he works better than hot.
    Maybe the problem with float level? I began to watch this problem when I lowered float level.

    Sounds too lean. Seems like an air leak. Make sure your pilot jet and circuit passageways are all clean, then use a high temp RTV on the reed intake boot joining surface.

    If this problem began when you lowered the float level, that could be your problem. If they are too low it will be lean.

    There is no reason to adjust the floats. If they are at stock setting leave them alone! Put them back where they were from the factory. Like everone else said check pilot jet/circuit and check for air leaks.

    Bit of background....have you pulled apart the carb? Have you changed the jetting?
    That hanging idle/fast idle indicates what the guys are saying...either a vacuum leak, block pilot jet or float level is too low or possibly stuck. Also, check you're throttle cable for any snags.

    You cannot problem solve without riding the bike...just starting on the stand only indicates the idle at cold conditions...what is the bike like at running temp and through the gears?
