I've had 5 igniters on my bike in about 1 1/2 years. One lasted a month, one lasted a year and one lasted a day. We adjusted the pickup coil to 0.8mm, cleaned all the grounds and added a few grounds during this time and nothing seemed to help. Triumph provided everything, no cost to me, up to the last one I got. They said "this is the last free one but you have to pay for , a new pickup coil, new coils and wires and new turn signal switch. I agreed cause it cost me a couple hundred bucks but still less than an igniter. Now my bike, an 04 America, came with an igniter part # 1291100 and that’s what was replaced each time except the last one. The last one was a Speedmaster igniter part # 1292370, I don't know what year that one is for. My igniter problems started in May of 08 and lasted till October of 09 when I paid for the pickup coil, coils, and turn signal switch.
Now for the good part. I don't know what fixed it cause we changed everything at one time, hey it was Triumph's dime so I wasn't about to argue about anything. It has run great to this day, hope I didn't jinx myself.
I wrote this as food for thought so it may help someone with igniter problems.
