I don't recommend having more than the one key. I use those plastic coiled up key rings in different colors to help identify what key goes to what. Lowes has them in about 10 different colors. I have a key holder (a strip of wood with a row of hooks) on my bedroom wall where I keep all my keys, a separate one for each vehicle. Having a number of different keys on the same ring will not only damage the lock, it will scratch up the whole area. I carry my house key/gate key/garage door opener on a separate ring, which does not have a vehicle key on it. I carry it, and whatever vehicle key I am using.
I have an '02, and just a few weeks after buying it new, the right side emblem started coming loose. One day I got on it, my pants leg caught on the emblem and ripped it halfway off. I removed both of them, and thats the way it still is. I thought about having some vinyl decals made by www.edecals.com
, which would be flush with the surface and not come loose, but never did. That is an option though, and would almost certainly be better than the stock ones that just won't seem to stay.
Those are another thing that got cheesier throughout the production run. My '93 had chrome sidecovers, and the emblems never came loose on those. Also, the first few years had Kawasaki emblems on the brake calipers, and stickers on the steering head covers and the coolant overflow tank cover. The blank spots are still there, but no emblems. I still think that the reason there are so many '85 and '86 models still around is that they were made much better than later models. They may have even lubed the splines on those models. I especially like the paint on the '86, I never did like the two tone tank with different color sides.
