I had a similar problem with my America, except the bike would start one day and not the next. I went out one day and it was backfiring and missing, parked it up had a look round could not find anything. It even went back to the dealer three times with the same fault. Then just before Christmas it gave up, luckily at my mates garage, he put it down to the CDI unit,
Triumph did replace it under warranty even though the bike was months out of warranty. The CDI unit is not cheap over here either at £300.00 ($600.00) +VAT (17.5%) + fitting and it has to be fitted by a trained Triumph mechanic
