Series 2, episode 3 - Honda Z50A mini bike
James is known for "doing things properly", but I'm afraid this was quite the bodge.
Torquing the wheel assembly with a medium "ugh"? Not torquing anything properly to spec?!
Fitting the front mudguard backwards?
On the latter, it's magically the right way around when we see the engine mounted (~ 17:30). Obviously he found the mudguard would foul the top of the barrel unless it was reversed...
Still, I love the show.
