H..E..L..P…. MY STOCK 2008 R3T, 17000 miles. 4000 miles ago while hot, I've had a miss only at steady cruising speeds, causing a stall twice, (started back up after 5 minutes). Seems almost like 1 cylinder is missing when hot while maintaining a steady cruising speed, or when backing off the throttle while cruising she will seem to miss and start bucking and jerking. Over 65-70mph is fine.Upon accelerating there are no issues, she goes…. Does not happen every ride. My mechanic is not Triumph guy but did the following;
Replaced the fuel filter and clamps, checked the fuel pump pressure at 42lbs, checked plugs/wires, and did a cleaning on the injectors and road tested it 40 miles. The problem was occurring when I brought it in to him, but was running fine for me for about 2 tanks of fuel. In neutral, if I throttle it up a bit and hold it, she will NOT hold constant steady RPMs, but go up and down as if there was a bad wire or plug. Acceleration is fine. Any help would be appreciated. PS I went looking to trade it in for another bike, but there is nothing out there like this! I can’t see myself riding anything but my R3T!

Had the same issue and took to dealer several times, they finally replaced the TPS and has corrected the issue so far. i have only gone about 300 miles since they replaced it but the cruising speed does not stall any longer. They would adjust the TPS and after about 50 miles it would get misadjusted again until they replaced it.
good luck
