Why do 2 cycle engines run hotter than 4 cycle?

A two stroke engine fires (an explosion in the motor) twice as often as a four stroke. A stroke is every time the piston in the engine changes direction. (From up to down) A two stroke engine fires every time the piston comes to the top where a four stroke will fire every other time. So if two single cylinder engines are running at 1,000 RPMs a two stroke will fire 1,000 times a four stroke will fire only 500 times. With twice as many explosions it will be hotter.
