Black Sporty was owned and built by Barry Cooney of B.C. Choppers back in the mid 70s. Barry was a pretty well recognized builder back then and a good friend of Arlens..
OOOPs.... I stand corrected .. I believe that may be Jeff McCann rather than Cooney... Like that's the first time I've ever been wrong..Hahahahaha..However .. that is definitely the style bikes that Barry built back then..
