XR 250 - what is too hot

Hi i just got a thermometer dipstick from xrs only and just wondered what temperature is too hot. My bike reaches fairly quick 200 after warming up then takes a fair while to reach 250, that is the highest it has got. Is this too hot?

I don't like to see it that high, or at least no higher. Do you get a hot oil smell when it's that high?

I've done a few things to keep mine down to 220-230 at its hottest. Make sure jetting isn't running lean, run a good full synth oil, I run the Two2Cool additive and I've wrapped my header. But mine is a 440 and it takes a little more to keep it cool.
