    I am trying to find out if the friction plate 22u-16321-00-00 are the same as the 4h7-16321-00-00. Hoping someone here can help me.

    No, they are not. If they were they'd have the same part number.

    I was informed the 22u number was an updated number for the 4h7, I recieved the 22u number when I ordered the friction plates for the 81 xj650. I know the 22u number is for my 85. That is why I am trying to find out. My local stealer could not help me.

    Don't believe so. The stock discs are about 3.05mm thick, check what the 22U's are. The 22U plate is used on a lot of late model stuff, and early Virago models........

    The part you need is: 4H7-16321-02-00. It's the replacement for 4H7-16321-00-00. The 22U-16321-00-00 is for the 81 750 Virago.

    Truth be told, the 22U-16231-xx-xx is used in about 60 Yamaha bikes from the early '80s until present day, every one of them a V-twin. From Viragoes (?) to V-Stars, '81 thru at least 2012, and every one of them is a V-twin.

    Carl is correct on the supersede, something minor changed. Those last two sets of digits usually reference finish or color which would not be applicable here.
