    CRF450R idling problems

    Yeah, I have to just barely crack the throttle when it is warm. It won't kick to idle when it's cold and the choke is on. I bought one of those Zip-ty fuel screws and it didn't help being able to adjust the fuel air mixture either.

    CRF450R idling problems

    This is to anyone that can help! I have an '03 crf450r that I'm having some problems with the idle on it. It either idles too low and stalls or of course I can turn it up all the way to the point of I may as well hold it at quarter throttle. There is no in between. It's bone stock except for a R4 silencer and I replaced the clutch. All the jetting is stock. It ran great until about memorial day and that was it. It's real hard starting, too. I checked valve clearances and they seem to be fine. They're a little tight but I'm within the + or - range. Any advice is greatly appreciated! Thanks, Bruce
