OK... I've done as much research as I think I can accomplish without spending some money and picking up a wrench... My Hindle exhaust will be here in a few days, and I'm ready to order my jet kit but I'm not sure what I want to order yet. The K&N/Dynojet kits are expen$ive, and I'm not sure I like the idea of using a K&N emulsion tube in place of the OEM one... I can get the "Factory" re-cal kit, along with some UNI foam filters for about the same money that the K&N or dynojet kits cost withOUT the filters... so I'm *hoping* that some of ya'all have used the Factory kits before, and/or dynojet and K&N and can give me some feedback about whether or not the K&N or Dynojet stuff is really worth the extra money. Keep in mind, this is all for an internally-stock street motor that will only occasionally see 1/4 mile madness or track days... I want to end up with a mild increase across the powerband, but throttle response and low and mid-range torque are *not* worth sacrificing just to see 2-5 more HP up top. My bike lives at 5-8K rpms most of the time.
