Finding indisputable facts for a go kart track may be hard to find. Location is the first rule of real estate, the question in some buyer' s mind will be does this hurt or help. I think that if the track is run till late at night, with music or loud noises, it would eliminate some buyers looking for peace & quiet. On the other hand, if there is a bowling alley and mini golf already there, it may be tough to overcome. The next buyer of your home may find the close by amusement a benefit, but no one can say how many buyers may be looking for this feature versus a quiet place.
