The RAM Ball C14-07 on the clutch side that replaces one of the bolts on the clutch clamps on the handle bar. Yes the sprocket nuts are just weight reduction, not that the OEM ones weigh that much either. When I was in the Air Force I was in Logistics. Just have an OCD for making things look clean.
