When I am riding, sometimes when I throttle down to change gears, the exhaust will give off one pop, pretty loudly. I was wondering if screwing out the mixture screw would help. Also, power down low is a little lame below 1/4 throttle. Could the two things be related? My setup: 2005 America, Sceptres, 130 mains, stock pilots, TBS needles, 3 1/2 turns out, no snorkel, in box K&N.
