I put a shim on my TBS needles today and resynched the carbs. I also did 3 1/4 on the mixture screw. Now my popping is gone, but I have a sputter right at about 1/8 throttle for a little, then if I twist some more, it goes away. Any ideas? Also, does the mixture screw have anything to do with synching the carbs? It seemed very difficult to get the levels right for some reason, wasn't a problem the first time. My setup: Sceptres, TBS needles, K and N in box, no snorkels, 130 mains, stock pilots.
