What will cause my engine to start to lose power and pop when I close the throttle while riding. See the picture of my plug.

Im not to sure but when a plug is really white like that i think it means its lean..is thier any cracks in the intake..did u take off the air box cover recently or add a pipe or port/polish without rejetting? Correct me if im wrong but i'd say your running lean.
You may be running lean...or the timing could be off a little

Well in another post I posted that pic of the plug and everyone said it looked perfect. I dont know. Is it lean? Or, is it rich?

is it dieing whn you let off the throttel or poping at high rpms?
check to se if your choke is one before you ride it then check to see if its on when you get doen rideing it.
i'd say it's running lean
