Hey guys, I hope you can help me. I have a crf450r 2007. My carb have problems when I want to start my dirtbike, most of the time I can't start it with kickstart, someone needs to pull me with a car, and when I'm using my bike if I'm on a curve, and I slow down the bike, it goes off. Some people tell me the reason what it happened is because the "valve, throttle" part: 16112-MEY-A11 is not working as it should. Some one can tell me if it is the reason why my carb isn´t working as shloud? or what else can it be? I really appreciate your time! thank you.
