Thanks Gary. I am actually planning on that and some other stuff to the carbs too. I am going to rejet it for pod's and open exhaust, I have 132.5 mains and 42.5 pilots. Thought about going up to 145 mains and 45 pilots. I want to get new needles that are adjustable as well, have to do some research there. Going with new o-rings on the float valves, and new diaphragms too, they have small pin holes and one has a small tear in it. What would cause the dark carbon like stains near the butterflies?
