I have a 04 CRF250,Is there a factory position. Or do I even Have a Thottle Positioning Sensor. I have one electric connection on the carb.is that it. App. any help. Thanks, Pacote

Usualy your TPS position is marked on the Carb with an felt pen from body of carb to the TPS sensor.

If it had to be adjusted you would need a voltage spec. at closed throttle.

I,ve tryed ajusting them use the voltage specs and had it work great on Hondas, kawis and suzukis. Yamha was way off so we use an S.O.P. gauge.
