At what temperature would you consider your bike overheated and shut it down to avoid damage?

 

If it gets too hot, it'll shut itself down before any damage can be done.

 

if oil pressure dropped ( due to viscosity breakdown)

if the motor started pinging



IF you feel that you have overheated the motor- change your oil as soon as you can.
Oil will breakdown if overheated ( dyno breaks down long before syn)- so change it.

That's a new one on me.

Where are you reading temperature?

My fans don't even come on until the ET is around 250.

 

I have the Power Vision. It tells me the engine temp. It normally runs 250-260 degrees. In bad traffic it jumps up to 340-360. Just want to know how hot is too hot.

 

Sounds about "normal". You likely wont achieve "too hot", just depends what your metrics are, but cooler is always better.

 

I think the PV displays cylinder head temp, which is different and likely higher than oil temp, I wouldnt equate cylinder head temp with oil temp.

 

I don't know which version he is running, but my PV2 reads BOTH head temp and engine temp., but not oil temp.

 

HeadT is not a "real" measured value, there is no rear head temperature sensor. Head T is as an algorithm based on ET and several other parameters, used by the ECM to manipulate spark timing tables, its useless to the user as means to monitor temperature.

 

I hope so if my oil temp was running 340 to 360 in traffic I don't think I could sit on the bike for long.
