Okay I am getting the HPI MT2 in today from Fedex. The temperature outside is 24 degrees. I have read that the engine needs to get to a high enough temperature to break it in correctly. I've also read about using aluminum foil around the engine to keep it warm. I don't have a heat gun to check the temperatures so is there any other test I can do. I'm really anxious to get this engine broken in so I can ride it around the streeet some in the snow so any advice would be greatly appreciated.
