[brettster26]

The petcock that came on my bike has 2 nipples and a union nut but is more square like this one http://cgi.ebay.com/ebaymotors/1975-1976-Honda-CB-550K-550F-550-F-K-CB550-petcock-/170703286008?pt=Motorcycles_Parts_Accessories&hash=item27beb56ef8#ht_500wt_749

and according to honda is unavailable  so i have been looking for a replacement.  Does anyone know if this one will work?
