My question is simply what Triumph is doing as far as a warranty for the labor and parts? Are they allowing an extended warranty on the engine to cover workmanship or is it an 'out the door and forgetaboutit deal?
Finally, maybe your loss in mileage could be attributed to, in part, a tight engine or maybe the new tune which I'm sure was loaded in your ECM.
Baxters probably waved goodbye and silently wished you not to come back...............
