An old set of handlebars that you never put away will work in a pinch too. Keep in mind the job of the seal is to keep the oil inside the engine from coming out. If you, as I did, change it with a full complement of oil (550=wet sump...), then all that oil will in fact try to get out, and quite successfully. I panicked, put the seal on, grabbed some old bars I had left lying around and they fit like a charm. Pushed it right into place with minimal spill.
