Got some 9 spoke wheels to put on my 88 fxr but I'm not sure what bearings I need for the rear wheel. One side seems to use a timken bearing and the other side has a larger opening for I don't know what. Any help is well appreciated

 

I'm not sure what you have there, unless perhaps it's a saidecar wheel (that's a guess!). Call over in the Evo section and ask again - they're a knowledgeable bunch over there.

 

Adding to my post above, early sidecar wheels had a drum brake mounted on the inside, with the inner bearing set in the drum, and a tapered bearing on the outside of the wheel. I can't find anywhere to confirm that, but we also have a sidecar section, where they may be able to help. Worth a try!
