i just purchased an iven tre for the 06 zx10, im an experienced mechanic, when finished we also did my buddies 07 zx10, we went for a ride, everything ran good, but we both noticed that our speedometers dont work! what in sam hill is up w/ this? the directions, or ivans web page didnt say anything about the tre disabling our speedo,s. has anybody else had this problem? or does anybody else have a tre installed?
