I’m the 2nd owner with 9600mi 2007 majesty. run only on non-ethanol but sits a lot. On my annual maintenance ride it began stumbling when I try to open the throttle. Accelerates and runs okay at part throttle. It stalled at a stop sign and won’t restart. The fuel pump is operating to pressurize and turns off normally. The plug had minor carbon but dry. Where to start?

You'll find that the one screw to access the diaphram virtually impossible to get at. Use a hole saw (1/2"or 3/4") to drill through the heavy aluminum cross brace right over that screw. It will not weaken the brace, either. Be sure to cover the engine with capture all of the chips. Magnetize the screwdriver so you don't drop the screw, and you can get access to the diaphram easily. No need to remove much of anything.

Hola me pasó algo parecido en mi Majesty 2006. Cambie diagrama ya que tenía 2 rajas y seguía igual sin fuerza. Y al final fue el sensor de posición del acelerador TPS. Revisalo por si acaso ya que estás en el carburador. Este problema casi me volvió loco. Espero te sirva. Un saludo desde España.
