You should never tune an engine to any certain temperature but tune it for performance and as long as the temperatures are between 220 to 280 it is OK. If I made a guess I would be guessing you are running pretty rich and not getting all the performance out of it!
i think i might be running kinda rich as a tank of fuel only last me a good 7 minutes or so
then again that sounds about right for a 75 cc?
