FJ1100 continuous idle stalling

Hoping the wisdom of this forum can once again assist:


I'm having an issue with my bike continuing to stall when not choked.  If i have any gas applied, it runs fine, but coasting or at a rest it stalls.  

What's been done:
- all 4 carbs thoroughly cleaned twice
- carbs synched with a manometer
- fuel tank emptied and thoroughly cleaned.  No rust present
- new fuel filter installed
- spark plugs replaced
- spark plug wires replaced
- engine compression tested on all 4 cylinders - between 120-130 each

The carb jets were upgraded a few years ago with the DynaJet kit,  ignition upgraded to a DynaTek 2000, and the engine was professionally rebored to a 1200.  Speaking with my mechanic, he suggested that we increase the pilot jets, as he thinks the idle is being starved.  My concern about this is that it was working for several years on the current configuration.

Anyone have any ideas on this?  I'm scratching my head.  I'm not opposed to increasing the jets, but they are already significantly larger than the originals, so I just don't want to go down the rabbit hole with this.

Thank you in advance!

Weighing up everything you say, sounds like it's just idling too slow - bump the idle speed up.
