i have 04 450 that i removed the grey wire under the tank as well as the throttle stop Mod as discussed in this forums. i also installed a JD jetting kit and the bike lost its off idle bog. my question is about my 2000 wr 400. i cut the throttle stop on the carb but never removed the grey wire under the seat. why?? becuase i couldnt find a grey wire. does the earlier model wr 400 have a wire for the tps that needs to be removed like the 04 WR? if so what color is it and where is it located. i couldnt find anything in the threads on the older wr 400 nad the only grey wire under the tank is to the kill switch.
