50mm O.D. on the air filter end of the carburetors.
Jim sells a K&N ham can filter for the kit separately. I would imagine the ham can is not as good at higher RPM as velocity stacks or short cone style filters, but the carburetors could be tuned well enough to make a street bike rider happy with a ham can.
As far as getting clean air into the engine, none of the oil soaked gauze filters are really worth a damn in my experience. An ugly foam UNI filter does a better job. The stock box probably better yet, if it uses a paper filter.
Unless Jim has the CRS carburetors stock piled, there aren't any available from Keihin until late November 2020. Source for that information is Sudco USA.
