How does it idle, and how is off idle response? You may need a 42 pilot depending on temp, elevation etc.
Hard to start on the kicker first start of the day, or consistently after the bike is warm?
Try adjusting the air screw all the way in and then say 4 turns out. If it starts better fully closed you probably need a bigger pilot. If it starts better with it four turns out you would need a leaner pilot, but I think that is unlikely.
