G'day members,

Have a 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*, this duration is wrong, should be 242*
EO 37* bbdc, EC 11* atdc, duration 216*, this duration is wrong, should be 228*

Does anyone have the earlier versions of the Workshop Manuals, that shows this cam timing spec??

Is there a later version of this Workshop Manual, with these specs??

Anyone with the Haynes Manual, please post the specs for the 790cc America/SM

Thanks..............agro
