I have been reading through the posts but I'm just as confused as when I started!
I have an arrow exhaust to fit to a regular 1050 Sport, no mods. I plan to open up the second airbox hole as well.
My bike currently runs sweet as a nut, no snatching whatsoever so I am very happy with it. The exhaust is for weight reduction really. I want to keep the low-speed smooth running so what tune do you knowledgeable folks reckon I should start with?
