Fair enough; thanks for the replies. [2010 w/ABS, blue
] The bolt and nut I actually specified and ordered were 92153-1877 (8 x 50mm flanged bolt) and 92210-0325 (8mm nut). There are two of them, and they hold the upper cowling bracket to the frame. If you look on any body else's Upper Cowling fiche (other than Ron Ayers) it shows that the bolt has now been supersceded by part 92154-1348, which is a 53mm flanged bolt (which they sent). all fiches I've seen still show the 92210-0325 nut. When I emailed Ron Ayers they had sent the wrong part they replied:
" The substitution parts are done by Kawasaki as a service replacement. Part number 92210-0325 is no longer available. The new nut (92015-1432 ) also included a new matching bolt part number 92154-1296."
They also sent the 48mm bolts. So what I have now is two 48mm bolts, one 50mm bolt (OEM), one 53mm bolt, and two 8mm nuts. Again, my concern is I don't see anything from Kawasaki that these nuts go with any of the bolts (even though they're all 8mm with the right thread pattern). Are there any service bulletins available to the public to show this?
Thanks.
