2006 WR 450

backfires runs rough and stalls

so? fix it.

is the bike stock ?......has it done this since you have owned it ?......do you know what jets are in it ?

atleast start by cleaning out the carb and see what jets you have then compare what you have to the "pinned"

threads in the wr forum.

if your bike still has the AIS, it will cause some back firing on deceleration. this is also covered in the "pinned" threads
