My Only Dyno Run

This is the only dyno chart I ever got for my bike so far. This was done about 4 years into ownership and twiddling around on my SeatOfPants Dyno. I think I have it dialed in assuming I am  running drilled out stock mufflers.

Before and After

When I bought my 2004 HD Sportster 883XL Police Edition it looked like a blank slate, which is one of the reasons I liked it. Second picture is what it looks like now minus the slash cut "Scripted" HD mufflers. I now run stock mufflers drilled out 7/16".
