yfz 450 2008 problem

[Vicente Irurita]

hey i have a 2008 yamaha yfz 450 and i am having some problems when you have half throttle it starts like limiting or like trying to drown but it`s not the same they`ve told me to change the cdi because the atv is modified with yoshimura exhaust high flow air filter but i changed it and nothing happens then they told me to change the starter coil and i did it but still the same i wonder if anyone could help me or has the same problem

You replace stator/pick up coil. And if yiu have a dynojet kit throw it out
