Thanks for the responses! I was going up a hill, not super steep but sustained. The top end in Colorado is lacking and the main reason I wanted to open this bike up. I was planning on swapping plug 1 with 4 and seeing if the color remains. I'm assuming your thoughts are the injectors are delivering equally and the power commander delivers to all cylinders/injectors equally as well? I'd love it to be the simplest and maybe the reason the bike seemed like a dog in stock form. The bike has always idled and sounded smooth, never ran or sounded like it was missing. I pulled the opposite outer plug before I did the mods to see how it was running, so I don't know if the rich cylinder has always been rich or only after adding the pipe/PCV. Thanks again for all responses and I'll report back what I find with the plug swap.
