As with most things , richening the motor will slow it , unless it was past the maximum lean point and peak power drops off.
But youll find the motor overall will keep power. If anything it was probably just a high idle and when you heat the motor up it makes your low-end leaner which makes it idle high.
Just try simply taking the idle speed down now. That should fix the problem. Another way to tell is after the straight if it keeps rpm up high for too long....
