04 stock needle is very good! It was the 03 needle that stunk and 05/06 is not adjustable! :thumbsup:

The stock needle works great... No need to replace it unless it's damaged.

The YZ needle works real nice... I'm sure that the YZ needle is close to an 04 WR needle, both work just fine.. The tapers might be a little different but not anything to drastic to make a performance gain.. (IMO) :thumbsup:

GDDUS needle came stock with my bike, as did the YZ throttle stop.
I think this is out of the AIS kit, as we don't have AIS on our bikes either.

This needle works good, but JD needle slight improvement.

I did the jetting with the GDDUS needle. The bike runs just fine, starting is a bit of a problem still. Going to install a 72 starter jet.
Check for it under jetting...
