Idle mixture screw caps have been removed already. I tightened the closest idle mixture screw (left side) down then backed out 3 turns. Far (right) idle mixture screw seems to be at the same position (I assume you must reach this screw from the left side? Trying to go in from right side there is a lot of hardware blocking).

Another scenario: Idle when bike is on side stand is ~1300RPM, when I raise it off the side stand it goes up to 2000 then back down when I put it back on side stand. In the video you can also hear the 'CLICK' and drop in RPM below 1000

Also when I'm at 2000 RPM, and I close the throttle by pushing it further, it seems to drop down. However when I look at the carbs throttle cable, there already seems to be slack just releasing the throttle. Continuing to close the throttle manually just looks like its giving it more slack. Could this be a cable problem?
