I love that bike. Sold my right side shift Bonnie (year model before this one) to a bud that still rides it today. Yeah, he has a Goldwing for two-up with the wife to the Eastern Shore, etc. But for pure riding fun, the Triumph wins hands down
They handle well and they'll pick the front end up any time you want if you know how to ride
You did tickle the carbs right? If not, it won't start.
Do you know that it has spark?
You have been through all the wiring ground locations, all clean and tight, and no wires are broken?
Headlight bright?
The thing about "attention" is way overblown. You can convert to pointless ignition, but why ... Points work fine and the amount of miles you put on a year means doing one big good winter service each year and just riding.
Unlike a computer controlled motor, this can actually be fixed with hand tools. And there are "Trumpet" owners in every decent town in the USA that will give you a hand if you need it. Every Indy bike shop knows who they are and has their phone numbers.
Join the local Brit Bike Club, you'll have that thing singing in no time
If it has compression (resistance when kicking), has spark and it's timed close, all it can be is fuel. Push the tickler buttons down until it drools just a bit from the carbs, kick it over
If it won't light first or second kick, it's not happy. Find out why ...
It's a good investment and the value is only going up, unlike recent bikes ...
