hey guys just stripped down a longtail I recently got my hands on. It leaked grease from lower, and upper bushing seals and grease fitting when we first ran it, come to find out that when I took the seals off to replace that both brass bushings were in needing of replacing, so now I'm debating whether to go back with new brass bushings or convert over to sealed bearings. I don't have very much knowledge of these longtails (other than what I've read on here!!) and just looking for suggestions.
