125-200cc WRE Temp Sensor

So, finally making progress on my bike....

Found out its a WRE not a WR, fixed most of the dodgy wiring and ignition issues and hopefully well on the way to resolving the power valve problem....

I'm after a bit of clarification regarding some sensors....what do the TPS (Throttle Position Sensor) and Temp Sender (in the top of head) actually do?

TPS - does this have anything to do with ignition or just oil mix?

Temp - this is broken, is it needed for ECU or did it just send value to dash (which I don't have)

Thanks
Chris
