Did you try different RAVE valve housings? I was thinking you could swap the whole ones over from the ski you borrowed the carbs from. Both slotted and the early flat ones will run right with the good housings. There was a service bulletin in 97 about the issue you describe it is most commonly found in early 97 GSX's. I ask because it sounds like you may have ordered the blades by themselves. My mistake if I'm reading that wrong.
He has one cylinder at 130 psi and one at 100 psi. Time for a rebuild.Doesn't 130 psi seem low? I know you have installed a new rectifier, but did you rule out your stator before you put in a new stator, since your issues don't seem carb/ fuel dilivery related. Did you rule out the battery with a load test?
