To be honest, I understand and comprehend the explanation from the video much better than my mechanical school, once again thank you, I have subscribed and not skipped the ads that appear to support the channel
I just wish Keihin made the PWK in larger bore diameters, because then I wouldn't be buying racks of 4 Lectrons when building PM Suzukis.
