From Grind Hard Plumbing Co:

This is our Power Wheels Barbie Jeep off-road go kart with a CRF 450 dirt bike engine. This week we take the custom off road go kart to a mudding event in Canada! And she rips!

This is turning out to be one of those when mechanics looses their minds or insane engine swap type builds. Can we really even call it a go kart any more? or is it more of a front engined four wheeler. Maybe a custom tube frame off-roader.
