I added these in the last couple of days and thought some of you might want the results.
Setup: '03 KDX220 - No airbox lid, low tension carbon fiber reeds, FMF torque (-35) pipe, stock silencer, RB carb mod, 13/52 sprockets.
1st: FRP Torque ring - Significant low end boost. Shortened the "Dead Zone" between "Idle" and "Power". Good power comes on much earlier.
2nd: Replaced CEK with DEK needle. - Slight improvement in bottom end response.
3rd: Moose Reed Spacer - Seemed to further improve snappy response across the whole RPM range.
Before making these 3 changes, I could not get a 4th gear power wheelie with the Torque pipe (only with the Rev pipe), But Now I Can!!! These 3 mods seem to work very well with the torque pipe. Granted the FRP Torque ring seemed to make the largest improvement, which may simply be because I did that one first!!! Anyway, all 3 only costed about $60 total, so why not!!!
