I've been researching how to determine what is what on these carbs and im getting confused. There are 3 screws located under the carbs facing toward the engine, these have little tabs on them that are able to make contact with the float bowls, rendering them unadjustable with the bowls on. My question is, are these the air/fuel mixture screws? Why would #4 not be there? Also would I be able to richen my fuel mixture by backing off my pilot jets?
I'm running stock air filters with a 4 into 1 exhaust and from what I've gathered, I shouldn't require rejetting. I've tried 107.5s and it doesn't run as good as the stock 102s on the mains.
