All tests needs to be done with
airbox installed and connected to carbs. It does very important function of smoothing and providing laminar flow of air into carbs. If you search on here for "pod filters", you'll find every case of pod-filters having mid-range problems are resolved with re-installing factory airbox and jets. Simple enough to tighten hose-clamps on carbs to rubber manifolds. Then slide airbox onto carbs once they're firmly held in place.
I started racing these bikes 5-yrs ago at tail-end of 35-years of trial & error development between millions of 250 racers. Those who've come before me have compiled extensive list of upgrade-mods for these bikes. Even though rules allow it,
not a single racer amongst MILLIONS used pod-filters because they provide zero gains in performance and introduces too many problems. Stumbling and surging mid-range is biggest issue, not to mention instability in cross-winds. Racers are lying cheating bastards who'll do anything and everything to gain an unfair advantage over their competitors. They only use what works, pod filters don't.
Need to test these with airbox installed:
1. Do clearing test outlined above. Then start bike with no choke. Does it start and run better?
2. Do same clearing test again. Start bike with full-choke. Does it start & run better?
3. what procedure did you use to clean carbs?
4. which one of these needles looks closest to one you have in bike?
