I called DynoJet directly and talked to one of their techs. Of note, there are two things to be aware of:
#1) The DynoJet "kit" is "tuned" for a stock configuration (carb/motor(manifold/cam,etc.)/exhaust). DynoJet specifically said that their kit is "tuned" to a stock configuration and that their claims are only supported for stock configurations. For this "tuning", aka expertise, they beget an $85 sticker. DynoJet said if you, for example, removed your airbox, then their "tuned" kit might not apply to your bike. This is to say that the more mods you've done, the further their "tuning" goes out the window.
#2) You can buy everything in the kit by the piece from DynoJet, except for the needles: To get the titanium needles, you have to buy the whole kit. DynoJet did not know how Keihin/Mikuni jets (part numbers) cross-referenced their own jets (part numbers). So, if you wanted to use their kit (needles), and you knew what jets you were running, and you wanted to match them up with their jets, DynoJet does not know what jets to substitute for them.
As for me, I'd really like to try out their needles, but not for $85. In the end, the only thing I bought from DynoJet was their springs. I'm thinking maybe their springs are a little lighter than stock and I'd really like to get a wee bit more throttle response from my drilled slide.
