When starting up my XRV 750 - RD07a the temperature gauge goes straight up and past the high mark.
It doesn’t seem to be running hot as almost happens straight away
Can any one advise if had same issue and what may be causing it ?
Is it a thermostat issue or and issue with the gauge what do I need to check first !

From what I can see on page 3-4 (page 4 of section 3: Cooling) of the Haynes manual that the temperature sender is on the thermostat housing, on the left side of the bike.

This is from the Factory manual. Hope it helps and I've not broken any rules posting it.
The gauges do tend to run on the cold side ( not mid way like you'd expect).
I'd be looking at the sender as mentioned above.
If you fit a new one, ptfe tape will seal the threads.

Hello Juberg,
According to the Haynes manual the sensor is connected to the temp gauge with a green-blue stripe cable. Since the sensor is a NTC resistor you might have a short circuit to ground. This would result in a infinite high temperature. From my memos when I tested my sensor when making the custom lcd dashboard I have 1076 ohms at 8 C and 32 ohms at 97 C. Maybe you can measure it's resistance. At 22 degrees C you should get 600-ish ohms. I doubt the sensor could be damaged. Maybe the cable is the problem.
Hope this helps!

Bardley, I couldn't find any rules mentioning it's not allowed...
