Robert_Brazil Posted December 15, 2004 Can anyone tell me what the stock needle for the YZ450F 2004 is? The part number is 5TA-14916- with seven combinations for different needles (YR, YS, JN, JP, J1, JR and JS) I am inquiring this as I own a WR450 and just bought the YZ exhaust cam to spice things up, but want to know if the needle change is also recommended, and if so which Yamaha needle is most appropriate for me (other than the JD kit) Share this post Link to post Share on other sites
