| Standard SS pump has proved OK and is what I'm using on the Class B bike I'm building. Even the Vacuum operated pump on the Monster 600s works OK, although a couple of people have replaced them with pumps from other carb'd bikes like Yam R6, CBR600 (mid 90s models) and ZXR400s.
Never measured the pressure on these as its quite low as they only substitue a gravity feed
on the injected class A bikes a 3-Bar bump is used
