Puch and Tomos bikes is mostly all what I tune, I never retune my bikes for winter or summer jetting ever and none have stock airboxs all aftermarket metal type or k&n (one has a polini space filter on it though) I run the same jetting year round on every bike I own, none ever spew gas on my leg, I can (and did) ride almost any one of my bikes with dress clothes on and pant legs and dress shoes stay clean.
Notice very little difference (except wet and sometimes ice on outside on of carb on very humid days) from season to season running wise, all start easy and all idle for days, (A bike that starts easy and idles good usually is indicator of a good running bike)
A55 box is ok (and great for use with stock exhaust) but a large mesh filter just gives that little bit more power and speed when used with aftermarket exhaust no matter how you modify the (rectangular turbulence causing) stock airbox so if you want a few more mph and bit more power the large mesh filter with bigger jet, middle clip on needle in the easy to tune phva 14 carb is what you want,
The phva 17.5 carb Will give a few more mph and even a bit more power even though the stock intake is barely over 15 mm stock, (I like to bore dremel them a bit bigger to just over 16mm), I wish they would make aftermarket ones exact fit that are 17.5 MM because I like running side covers
