After a crash-tastic lesson in flat-track racing, Zach's on a quest to convert an ancient Harley Sportster into a flat-track race bike. This challenging build leans heavily on Jim, the tater tot–loving lead fabricator. Normally low-key, Jim starts going off the deep end when his beloved tape measure goes missing. If that isn't enough, Zach turns up the pressure by adding a high-profile project to the mix — customizing a Victory for a premium Red Bull event with BMX bike champ Corey Martinez.
