boggy running between 3-5k at 1/4 throttle

Hi all
Finally got the KR-1 back together after a crank rebuild. The carb problem that was there before the rebuild is still present, so I need to have a go at that now.
The bike runs ultra smooth from 1-3K RPM, boggy between 3 and 5.5K RPM, then back to smooth from 6-9K RPM. I've noticed that in the boggy range, if I turn it from about quarter throttle to half, it starts to rev a bit nicer and then pulls up to 6k+ where it's far happier. Unfortunately 4-5K seems to be the rev-range it wants to sit at on most legal road speeds (my RGV generally sits around 5-6K).
Presently there are new #38 pilot jets, the main jets (#135) are old, the N68A needles are new. The needle clip sitting is currently in the middle, I'm thinking I need to try adjusting this as a start. The bike itself has 49,000km on it, most of which by the previous owner, so I've never really had a good baseline to go by.
Thanks for any help
