sounds like a major pain in the butt. just changing the clip position on the j.d. needle made a big differance for me.
one thing you can try for free is to adjust the accelerator pump timing. it's on page 4-19 of the '03 manual. give the screw a half turn both ways to see how your bike is affected. it may help you decide if the accelerator pump is where you want to go to dial in your jetting. you may even find out yours was out of adjustment to start with.

If the problem is too large a squirt, then the leak jet or diaphram are the only way to adjust that.
The thought I had was to delay the squirt and then lean out my pilot. Is that nuts, too? Anyone?

It seems that some members of this forum suggest a JD kit for anything that ails them. Got a sore throat, get a JD kit – got a bog, get a JD kit.
For those of you with a kit installed, what suggestions do you have for WFO_IN_IT? I am curious what the next step will be.

We're all talking about the same thing, right? Crack the throttle at idle and there's a quick bog (maybe even dies) and then it takes off. Mine does it a lot more when it's colder than hot.
Too lean? Too rich?

as mentioned before, our carbs give us the ability to set the squirt timing. the manual gives the factory setting. the timing can be advanced our delayed with the turn of a screw driver. if some of us don't seem to be fighting the "bog" and others are (j.d. or not), this might be worth checking out. it's free and might give a hint to the problem.
just my thoughts.
forget i said anything about the needle clip position. it wasn't the original question.
grahmo, your's sounds lean.

I have no bog or hesitation. I believe fine tuning the Accelerator pump will help all you guys with 03's and 04's with this issue.
I agree the acc pump is what you need to mess with and it got rid of my bog. Don't forget to have a fast idle as the flywheel is larger than the YZ and needs a running start.
