Here are the basics of engine cooling as I understand them:
* Be sure engine operation is not producing excessive heat (e.g., timing and air/fuel ratios are correct).
* Coolant is circulating freely through the engine and radiator (e.g., no air bubbles, functioning water pump and thermostat, clean radiator interior).
* Properly sized radiator for engine and conditions (check manufacturers recommendations).
* Adequate air flow through the radiator during all operating conditions (e.g., good fan(s) and shroud, and no obstructions limiting air entering or leaving the radiator).

Given that your engine is new, I suggest you start by looking at its tune. The next thing I'd check is for air in the coolant system. If both of them are right, next look at how air is getting through the radiator. A good shroud can make a lot of difference. When all of those things are right, if it is still running hot, then a higher capacity radiator might be in order.
