I mean it's REALLY rich. Leaves black stuff on my lower pipe.

My 2005 victory kingpin runs rich but if you lean them out you get that “HORRIBLE POPPING” sound. I clean my bike after every ride. The back fender gets black on it also. It’s not a big deal to simply wipe off. The backfiring sound isn’t acceptable to me so using a bit more fuel is totally acceptable to me.
