RMZ 05 Bogging ?

[pj151]

Just picked up a Rmz250 05 it has that bogging problem when you crack the throttle after it is warmed up , and popping when decelerates. It sounds to like time for jetting change. Temp is still in the mid 30's to 40's. Any suggestions.

check that your inlet rubbers on the carbs are all real tight this can sometimes cause popping..

Popping on deceleration can also be caused by a leak in the exhaust.

Change your pilot jet to a 42 and your air screw 2.5 turns out. Worked for me at an elevation of 500ft.

Hey Thanks, All that is just what the doctor order 42 pilot 2 1/4 turns good. Also changed exhaust to FMF everything is sweet for now.
