Dulcinea wears Polini filters and I´ve cought them with stainless steel stripes > manifolds last a lot longer than on Rocinante with the 350 air box. If you don´t catch the carbs using pot filters, you´ll be in trouble for sure!
I really must try the Pollini elbows/filters again. I still have them somewhere. They required
much smaller main jets than the S&Bs with everything else the same, so my false 'logic' made me think I would get more power with those
Possible to tuck them away better though even on a 350 in a 250. Then I don't usually ride the 2C/375 fast enough for air flow in to the rear pot filter to matter these days - too much vibration

Yes, the Polinis require smaller main jets than the K+N replicas I used before (115 to 130 more or less, both with slides 50 and 268T atomizers). To fit the Polinis I had to add some O-rings on the carbs. Rocinante with the 350 airbox (no matter if there are filters inside or not) needs main jet 130, also with slide 50, 268T, 45-42 idle, X18 needle (at another height than with Polini)
