I wouldn't let those guys work on a rock. The same bike was on ebay recently. Canuck750 has a pristine one and at the opposite end of the spectrum, I have a crusty one. But, it was free (thanks to Ron Komoroski).

I know nothing of their mechanical skills, I only watch select episodes for entertainment. Some of their episodes are kind of like the cable shows top gear and American pickers, both of which I have only seen when staying in a hotel room.
