Marcel when tuning the carby’s, what is the process in basic ?

I have tried to bench sync the carby’s the best I could, but the bike really bogs down while riding at 7+ RPM in any gear above 2nd on acceleration. I adjusted the fuel screw while stopping the bike on a ride.  But this what I thought was over fueling on acceleration and screwed in to about 1 full turn from seated in, it ran a bit better, better rev’s higher and smoother. It must have been very lean. Its still not rev’ing right up.

I have just made the fuel mixture screw 2 1/2 turns out for now,

What other adjustments can I make?
