Named for Indian's legendary 1000cc side-valve V-twin of 1916, this Powerplus was intended to silence critics-like us-who dismissed the earlier Chief twin as an obstinate amalgamation of cloned H-D parts. It didn't work. Marked by a chronic inattention to detail, many Chiefs were apparently assembled in the dark. The 1638cc twin powering the last of the Gilroy Indians was reasonably smooth for a solid-mount 45-degree V-twin without any internal vibration-canceling apparatus. Pages snipped from Harley's Evolution Big Twin playbook meant the basic design was sound. Implementation, however, was not. Let's just say quality wasn't exactly job one. Oil leaks come with the territory, along with loose bolts that contribute to an ingenious weight-loss program by allowing various bits to fall off at random intervals.
