High Idle even with Pilot Screw all the way in.

[rider_al]

Hi All,
After my bike has warmed up the idle is still very high even with the pilot screw all the way in. I was hoping that the engine would cut off when idle but it still revs high.
I have checked for vacuum leaks ( sprayed cab cleaner around the boot) and it doesn't rev up. So I don't think this is a problem.
Could it be there is a leak with the pilot screw ? Mind you I have replace the pilot screw from a new rebuild kit and it still idle high when it's screwed all the way in.
Would appreciate it if anyone has any ideas.
