              Just one question , do all xtz pop on a closed throttle (to many two strokes mean I have a habit of blipping the throttle) the bike is in standard trim.

         Yep, they all do that. It is just an emissions device that bleeds air into the exhuast on a closed throttle called "AIS" (air injection system). It can easily be blocked to prevent the popping with no ill effects on reliability, performance or economy.
