Triumph Workshop Manual for Bonney/Thrux/America/SM, P/n T3859909-1, Issue 4, 10.2004
Checked the cam timing specs for the 790cc America/SM in Chapter1, Page 13 - General Information, states:
IO 19* btdc, IC 43* abdc, duration 228*,
EO 37* bbdc, EC 11* atdc, duration 216*,
Intake duration as listed is wrong, should be 242*
Exhaust duration as listed is wrong, should be 228*
