Tom-
On the 32mm, metal slide equipped carbs....non-adjustable, original needles are N52H in lh carb, N52I in rh carb. Are you using these? With what main jets? Frankly, kit tuning components are notoriously "copy-cat" crapshoot, may work, may not. Kit is meant for your year 250? Or a more common later model? Note 32mm metal slide carbs only used in 86-87 models.
Check valve timing/clearances as yet? Truly clean carbs/circuits?
