if it is original and not the upgraded gold headed bolt , don't adjust until you obtain one. This is a very important update and the
adjustment of the rack damper bolt is very critical. It
should just barely make contact and damp the shake (when
EVERYTHING is running correctly and the engine is WELL
warmed up) then loosen it 'til it shakes - then tighten 'til
it just stops shaking. Then tighten it down. I played with mine over several days
Pretty scientific huh
