That thread was a blast. There is some good stuff buried in there but mostly the blind leading the blind. All well intentioned and people trying to helpful to be sure.
OK let's try a DIY approach. It's been re-jetted but needs to be adjusted. What jest were fitted and how is it set up? How is it running and what areas of throttle are good and what is bad? is idle and off idle OK but jerky on over run or choke at half throttle or dies at high revs or is it just a general question of how do you know when it's right, type of question?
Those bikes have a reputation for hard/cracked rubber manifolds/insulators. I'd check those first, then I'd get idle and off idle right. Then I'd run it flat out and do a plug chop to get the top end (100% WOT) and then finesse the midrange. The trick on P2 of that thread is right that the way to check part throttle is to start by marking the positions on the grip, so you can tell where you are.
You could also buy an Air: Fuel monitor but they cost more than a dyno session.
