Just get the 07 YZ needle.

It may not be the same one, but it WILL be an improvement over the stock POS needle and it'll have multiple clip positions too. Bear in mind that once you put that sucker in their it will no longer be legal on public trails because it is a closed course modifcation :ride:

Like anybody listens to the EPA anyways :ride: :ride:
