That's the EMGO Shorty Reverse Megaphone muffler. That's what was supplied by Ryca. And I settled on the same jetting, too! -- 152.5 main, 52.5 pilot, and a little over 2 turns out (I'm at sea level.) Don't know about the needle as I didn't go there. It has good dynamic response, so no need to. That is one loud muffler, even with the crumbcup and fiberglass packing added.
I'm averaging 55 mpg on a 16 year old engine with 22K on it, but then I rarely go over 65mph (bicycle computer calibrated to front wheel).
