Brake lever for 1990
Thanks to everyone for the information so far. Let me respond to some of the points raised before this gets even more confusing!
My bike is a 1990 Kawasaki Vulcan 750.
According to the many Kawasaki OEM parts fiche sites, the part number for the front brake lever for this year is (in the fiche diagram) 46092. The fiche display shows only a rectangular master cylinder. If you look at the same OEM fiche for a 1991 Vulcan, the part number changes to 46092/A. The 1991 display also shows a circular master cylinder.
When you compare the two levers as they appear in the fiche, they are clearly different. I think I have successfully added an image to this post which shows the levers side-by-side as they appear in the OEM fiches (PartShark.com in this case). The one on the left is for 1990; the one on the right is for 1991.
I mean no disrespect to anyone when I make the following comments. Indeed, I may once again be only demonstrating my (sometimes appalling) ignorance:
Wolfie: I am confused by your post advising my lever must be from an 85/86. The fiche for 1986 does seem to show the same lever shape and design as for 1990. Perhaps there is a difference that is not obvious in the fiche? I do appreciate your offer to see if you have one. If you do have one in good shape, please let me know.
Knifemaker: Your post advising that the lever style changed only after 1993 seems unsupported by the OEM fiche material I have seen. The 1994 fiche, by the way, shows the same style lever as in 1991 although the part number next to the lever changes back to the 1990 number of 46092 and not 46092/A. Your suggested search at Ebay does turn up multiple levers of both styles. This is a big part of the reason for my confusion and hesitation to order a replacement. However, now that I have taken the time to carefully look at the fiche diagrams and create the attachment to this email, I have a graphic which should help me sort through the Ebay items and pick out the correct lever if Wolfie does not have one. Frankly, I should have done this before seeking help from the forum members.
Chucklesmii: See my comment for Knifemaker.
Again, I mean absolutely no offense to anyone who has been kind enough to respond to my original post. I certainly do not have the experience and knowledge that so many of the members of this forum possess, and I always appreciate any help I can get.
