Desnorkeled, unifiltered, drilled the slide, shimmed the needle (thanks xr650L Dave), and I LOVE IT! It is now wheelie time... I tried to remove welds that hold the stock tip into my exhaust and destroyed the part of the muffler that the tip bolts into. So, now I'm looking into an aftermarket exhaust (then I'll rejet.) Anyone use, like, dislike, etc...the Supertrapp IDS2? I've read the various opinions of the other pipes and don't recall anything on the Supertrapp. You guys rock!
