Question about suction sockets

Hello everyone, have several questions that I hope you can answer! So: 1.What is the ASA doing and where is it sitting? 2.Can a too small ASA pull a throttle? 3.Are 13.5mm too small for a 80s? (Seen from different sides sizes from 20mm, never 13,5mm or similar) 4.Could the ASA be narrowed by something in this so that it leads to a throttle? If you now ask yourself how I come to say that the ASA is too small/constricted on my moped The reason for this is that at alphatechnik.de, surprisingly, I found an expert report for my machine which says that it has open 9kw and 110km/h (from 5kW/80km/h to 9kW/110km/h without conversion parts). There, under modified vehicle parts, remove intake reduction, if necessary also outlet reduction. I have already removed the outlet reduction, according to vehicle papers an 18mm disk. 5.Is there an ASS that fits for my (Honda CRM 75)? 6 Could the original of Honda be bigger? (Was for the chain kit like this, before 13 sprocket and 48 sprocket, original chain kit of Honda:15 sprocket 48 sprocket) I thank you very much in advance and hope for your help! byebye
