My bike is not running smoothly. It's a 2011 Triumph Thruxton and it's under new bike warranty. I don't know how to explain the problem to the dealer. It's not running smoothly, usually in first and second gears. It kind of jerks (just slightly) but not violently while in a steady rev, eg. 40km/hr in 2nd. How would you explain this to the dealer?! I mean, I want to give them no excuse to send me away without looking at it.
