Just grabbed some 99 forks from a 400 to use on my 03 wr450. I was hoping for a stock set of springs but judging by the race tech sticker I don't know what I got. I pulled one and here is what I came up with. Wire diameter .192" Coil OD. 1.61" Coil count 27-28?? Rate is .45 @ 28 .46 @ 27 Here is a pic I don't know if what count is right.
