Here is the port side. We couldn't find a K-1100 exhaust that wasn't already cracked, so my tech friend came up with a way to mount the original exhaust to the later K-100RS/16V foot peg plates. It requires additional rubber mounts and an additional mounting plate behind the foot peg plate. I have since replaced the natural finish spark plug cover with the original black one and I have replaced the brake hoses depicted with shorter ones that rise straight up from the caliper.
This bike gets down the road smartly.
