Linkert M53A1

3 Line, 2-418, 1954 – 1956 KH MODELS.  There quite a few different models during the years 1952 and 1956 when the K models used brass Linkert, and many were in racing and hill climbing configuration. The M53A1 like all the M53 series came with a double or duel venturi often referred to as a Bombsite verturi. And the M53A1 was assembled with H-D production K series models.
