Bob Hancock had a similar setup with a stock muffler. I think he was using the Booster Plug or something similar. I don't know if his set up eliminated the O2 sensors or not but someone knowledgeable advised him to do it. I can't remember who that someone was as that conversation was over 6 years ago. Hell maybe I dreamed it all.

I'm just saying make sure you are good to go.

Couple of stories of burnt / broken valves from running lean r1200s on this board.
