Hi guys,

New to the page but I’ve got a 2013 KXF 250 and currently having issues where it’ll start and run/idle no problem but won’t run if I rev/give it throttle more than around a quarter turn, sometimes it’ll rev up and give me a few second of throttle getting the rpms up but then it’ll bog down and cut out will fire back up no issues whatsoever but will not allow itself to rev up for kin and cut out again and again after a quarter throttle valves & shins are fine/perfect and in spec and timing chain has been checked to make sure all teeth, notches, and link pins are correct and they are but still having the same issue, replaced the spark plug and still same issue no improvement guys what could it be as I’m scratching my head and really don’t want this turning into a money pit,
Any Advice Is Much Appreciated I also have a video of what it’s doing but can’t upload message with a contact method and I can send over the videos of exactly what it’s doing currently
(2013 FUEL INJECTED MODEL)
Thanks Guyz!!!
