Who can explain the "popping" on deceleration? I have the AI removed, and 2 stages out of the rear of my stock exhaust, and the snorkel out...but nothing else has been done to the bike..19,000 miles now...Im hearing that its a "lean" mixture, but I always thought that a "rich" mixture would cause this by putting too much gas into the exhaust....confused...I like the "pop", but want to correct if it's not a good thing for the bike...Pops louder after warm...
