Don't listen to keyboard warriors on what your jet should be, most of these people have hella air leaks. Aside from a starting point I really hate to even say. You can always plug chop too, as a sanity check, shas are notorious for running 'pretty ok' even when they are way off, and they are super touchy about air filter.
This is kinda why is hard to just jump into performance stuff, there is a certain feeling... I've heard it called 'la patate' ... Maybe 'the potato', although that is pomme de terre au francais. A guy on here used to say 'harmonious' like the engine is singing in harmony. When you've got it everything is just happy jamming along, like bob ross style. when you are off you won't see your full potential, gotta figure out why.
On the internet I have no idea what your bikes doing, I just know top speed. 8.5 is good c.r. your head is awesome, you might be able to futz with the shimming to get port timing better but I'm guessing your not getting everything out of your tune. I've hacked together way sloppier builds than that and had them in the high 40s.
