being closer to 66 now than 65 i have absolutely no idea what "who got the 411" means but hazarding a guess that your hipness is indicating a question?
1-BELT TENSIONER PULLEY all info below that i've provided numerous times. also clink link for instructions and pics.
2-EXHAUST PORT GASKETS same for all late model sportsters...tube frame AND XB frame buells. OEM PART # 65324-83B and available anywhere and everywhere for a few bucks a pair.
correct bearing part # is 6203-2RS-10......dimensions are 5/8" inx40mmx12mm....double sealed....QUANTITY 2.
look at link below for pics on how it's done. easy project with minimal tools and cost efficient.
and be DAMN SURE to mark the spacers "left and right" or you'll regret it later. avoid temptation to pack the new bearings with extra grease.
