took my 74 honda cl450 out for a ride and when i got to the end of my street started holding the front brake to slow down, then it all stated heading south, bike felt like it was chugging or something but it was all up in my front end. pulled over to look at it and my brake hub (drum brake) rotated and tore out my front brake cable and really messed up my speedometer gauge cable, under further investigation found that one of the bolts that holds the hub still was missing. has this happened to anyone else? is it common? i found the brake cable and have already purchased that but i cannot seem to find the speedometer cable anywhere in the usa anyone know where i can find one so i can get back out and on the open road??
