Evening all,
So my thoughts, when the carbs were off and cleaned, have the tiny little springs been refitted and relocated in the right place? I visited a chap in Norfolk who was experiencing similar issues and I found that springs were missing for the needles. Hsi bike had also been worked on and his carbs done by a local garage.
Not the diaphragm springs, but the tiny ones on the top of the needles! It caused all kinds of low down throttle issues that were almost impossible to find.
Also, the air cut off valves could cause issues although less likely unless they have been damaged when removed or not cleaned thoroughly.
I have air cut off valves available if you do want to try them but id first be looking at the needles so see if they have that spring in them.
