[cook05CRF450X]

I just bought the bike and found this place. NICE!
I've tried to read up on this but it's giving me a headache. I'm getting confused on what to do. Can anyone help?

The bike:
'05 CFR450X 180 miles on it! The muffler baffle is removed, rubber thingy on top of air box is removed, otherwise stock. It had this problem before the "mods" but I think it's worse now.

Here's the deal: When I snap the trottle open at an idle or when I'm moving along at a low RPM and snap the throttle open it stumbles and tries to die. I have to roll in to it fairly easy.

Can I adjust the screw that controls the accelerator pump or is it mandatory to buy a better pump cover or something else? I would prefer not spend any money right now, if that's possible. Gotta try to keep the wife happy. I know that's not easy...

Thanks in advance, Matt.

welcome to start things off i would clean the carb all jets and take notes of what size jets you are running and report back. pay close attention to the pilot jet as it becomes clogged quite often.

Welcome to the website. BTW it is a great place for advice and parts too. Their shipping is the best, course I live here in Ca and it doesn't have to travel far.
