In the second of a two-part special Henry Cole is at the Isle of Man TT where the legendary Norton are attempting to make a return after 20 years. They last tried in 2009 but failed to qualify. We return to the workshop of bike restorer Pete Thorne to see how the 1981 Yamaha is coming along. And whatever happened to those legendary Californian style choppers? And with the numbers of people taking a motorcycle test plummeting, Henry persuades restorer Pete and Chris 'The Stalker' Walker to take the new Compulsory Basic Training test.
