I have a 2008 with the following mods: block off plates, quickshifter (blue monkey motorsports QSE), Brocks full exhaust, Bazzaz, and servo eliminator. Currently showing a code 64 (Air switching valve malfunction, wiring open or short).
Any suggestions on what to check after making sure that all connections are solid? My brother put it together for me and rode it to make sure that nothing major was wrong, and says that it rides solid except for some slight decel popping at speed. He's a dedicated Suzuki (Busa worshiper more like it), and he had a big ass grin on his face after bringing it back.
