If the exhaust is stock, no re-jetting was needed on my Cb550F models.
I did the UNI Nu-4055 for economy. Stock paper filter was $50 and needs replacement yearly.
The uni is cleaned and reused. One lasted 15 years before the foam began to crumble. Which is why you should use the UNI filter recharger kit. Both the cleaner and the oil in the kit is compatible with the foam so it will last a good long while. Some oil additives and cleaners can attack the foam an lead to earlier replacement.
Cheers,
