I have an 04 that is completely stock as far as I know.I bought it used and it came with two jets and a needle. It pops when it is idiling and when I am deceling. is there a cheap fix for the poping.

What bike?

A leaking exhaust header off of the cylinder head can cause popping too. This can be excessive to the point where jetting can't fix the problem.

If we're talking about a YZ250F, turn the fuel screw out as suggested above as your first check.

:cry: Don't take out bowl plug. Go buy yourself a fuel screw like the ones zipty racing sells. It makes life and carb adjusting alot better.
