I removed the secondary flies, I did it while doing other stuff to the bike. In my opinion they are just another restriction I didn't need. They were not there on the original back in 99. I think they are somehow tied into the mode selector for A B C power ranges. Since I removed them I don't see a difference in power. I did not use a power commander, we have a local speed shop that tunes the factory computer. He charges $ 75.00 for a tune allot cheaper than a power commander and you don't have something that can break this way. I don't drag my bike just ride it like I stole sometimes
But I can tell you this that there is no comparison to this bike now and stock. My buddy has an 08 that is bone stock and I can walk him in any gear badly up to 155ish. We have gone no faster than that so don't know about the upper level but I am so far ahead of him at 150 I couldn't see him making it up before I run out of gear or road
I am going to get a dyno on it in the fall to see what it puts down. Visit my website to see my mods. They are the standard mods I think that most do.
