Carb problem

[brko]

Hi
My 650 is juddery and low on power below 4000rpm. It had new cables, both throttle and choke, new plugs and syncronisation. Only thing left to think about is plugged small jet?
I tried resseting the mixture screw today while the bike was running.
on one side of the carb it cut off as I turned the screw all the way in. on the other side it kept working? slower but properly working.
small jet plugged or something else?
Any thoughts appreciated.

may be diaphragm 16 in the above.. check that the throttle bodies move smoothly.. with the air filter off lift then fully open with you finger and ensure that they return smoothly, they should be easy to lift and smooth too..

no harm in cleaning all your jets but I would check the diaphragms first..
