ATTENTION: Select (19-20) model year ZX-10Rs are subject to a Kawasaki recall concerning a faulty ECU and suction valve (PAIR). Failure to perform this recall could lead to exhaust system damages/failure. Brock's Performance will not warranty any damages created from an improperly blocked PAIR and/or failure to perform the recall. The PAIR valve on the ZX-10R is blocked via the use of the supplied black cap.
