What DaveO430 just said.
I also note you said "reach the red", and that is NOT overheating.
It is just approaching the point where the fans should turn on and pull the temperature back down.
But, if in a parade as Dave mentions, between 15-20 mph, the fans as OEM installed, blow forwards against the incoming air... the result is a stagnant "dear air" space and overheating can actually occur.
What you need to do, if you have not already, is:
.... Reverse the power leads to the Fan motors so they will blow towards the rear of the bike.
.... Reverse the Impellers on the Fan motors so that the curvature is again properly positioned to PUSH AIR. If you don't they will not be as efficient as they should be.
You might wish to just skip the 2nd step IF the reversed polarity to the motors gets the job done.
