250cc 4-Stroke Engine Operating Temp

I just installed a Trail Tech computer on my Honda CRF250X (249cc, aluminum) and am looking for suggestions as to where to set the "High" and "Danger" setpoints (an amber warning LED illuminates when the high temp is reached and a red LED when the danger temp is reached). I'm thinking 230 for high and 250 for danger. The 50/50 prestone I put in it protects up to 265, so 250 seems like a good danger temp with a high temp of 20 degrees less. No clue if these temps are acceptable for an aluminum single cylinder motorcycle engine though.

Think I'll start with 210 and 230 and see how things go. If I'm constantly hitting 210 and not burping coolant, then I'll adjust accordingly.
