Re: The Ray - 2001 R6 Rebuild Log
There isn't a "base tune" aside from having OEM jets, af mix at factory spec, good vacuum, clear passages, working fuel pump and floats working right. If those things are present a mechanically correct engine will operate normally and be a candidate for adjustment with jets, AF tweaks and so on.
Your fuel pump sounds pretty reasonable, so that is probably about right. Over the spring that cb750 I did needed new float valves and bowl seals- have you had the bowls off etc? A few years ago I had dirt in my Bandit's fuel line which jammed up the float valves, caused all kinds of mayhem.
