FORK DAMPER VALVE, SPEC A

ORIGINALLY THREE SIZES OR TOLERANCES OF DAMPER VALVES WERE PRODUCED, IDENTIFIED BY A LETTER AFTER THE PART NUMBER.  

THE EXAMPLE HERE IS ONE WE HAVE HAD MADE AND IS A CLOSE TOLERANCE VERSION ORIGINALLY GIVEN PART NUMBER 14118A.  ITS OUTSIDE DIAMETER WOULD BE .678" - .680" (17.2MM - 17.25MM).  WE KEEP THE SIZE TO TOP TOLERANCE AND THIS HAS BEEN OUR STANDARD SIZE FOR A LONG TIME AND THE SIZE WE USE ON OUR DAMPERS AND COMPLETE FORKS.

WE ALSO STOCK 067633B (14118B) WHICH IS NOT AS WELL OR CLOSELY FINISHED AND IS A LITTLE SMALLER .671" - .674" (17MM - 17.1MM).  THIS WOULD BE STANDARD ISSUE FOR BASIC ROAD BIKES, FEATHERBEDS, COMMANDO, ELECTRA AND NAVIGATOR BUT REMEMBER THESE VALVES PRE DATE FORK OIL AS WE KNOW IT TODAY AND THE OIL USED THEN WOULD TEND TO BE THICKER.

WE ALSO HAVE 067633C (14118C) WHICH IS THE LARGEST VALVE USED WITH A CLOSE TOLERANCE DIAMETER OF .684" - .685" (17.36MM - 17.38MM).  

THE CHOICE ALLOWS FOR A LITTLE EXPERIMENTATION SHOULD YOU BE SO INCLINED.
