This is my first post so if I miss anything I apologize. My son received a Jakk's Pacific Mario Kart from Toys R Us a couple of winters ago and loves the thing. The problem is that its kind of a dud being that's it's 6v stock and only has one rear motor. So I swapped out the 6v battery and dropped in a 12v which was great except we have now smoked the gear box. Since I am looking at having to replace the gear box I am thinking of doing a transplant from something like a Power Wheels Jeep. I will require extensive modifications to the mounting but I don't see anything too tricky about it. For anybody that has added a second motor to a Power Wheels what were the major challenges? Any other ideas? Here are pics of the damage.
