1970-71, /5 fork mod

This floating damper modification is to greatly reduce stiction in the “US” models as well as the /5 series in 1970-71.  The last two years of /2 production, 1968-69, offered a new telescopic fork.  It was fraught with many issues.  Those forks also need this modification.  All of these models required fork alignment in order to work correctly.
