'79 special with stock pipes and uni foam air filters. I went up 1 size on my pilot and main and dropped the needle one clip (leaner). Bench synced the carbs. Bike starts up right away but idle is rough. RPMs climb even after putting a set of OEM Yamaha advance springs on. When setting the air/fuel mix screws, it runs the best with them COMPLETELY in. That is what doesn't make sense to me. I figured they would be somewhere around the recommended 2.25 turns out. Am I overlooking something? Maybe I missed an air leak somewhere?
