If it is idling at 11k or 25k - book it in to the Guinness Book of World Records
the "k" denotes thousands
but your problem sounds typical of the stuck float valve - that is not shutting off when the carb is full, then dumpng out the overflow tube/s....
see if you can locate which tube it is coming from when the bike is running and on the centrestand- then you can have a good look to determine where the problem may be... if on one carb only - try tapping gently the float bowl with the plastic head of a screwcriver - this might help just shake the valve a bit...
