Hey everyone I just added the speedster longs to my 2004 X and now I'm experiencing backfiring. Can anyone suggest how to adjust the air/fuel mixture? Location of screw to adjust and which direction to turn? Thanks in advance. By the way they sound amazing!

Does the bike still have the PAIR system still on it??...If so, do that mod before messing with the A/F screw...Also aftermarket exhaust systems have thinner flanges than stock, so the acorn nuts bottom out before sealing the pipes in the ports, creating an exhaust leak that will also give you decel popping...Add a washer (or two) under the acorn nuts to fix that...
