Have you done the BK mod? It is specifically for your bike (YZ/WR426's) as you don't have a leak jet for AP squirt adjustment.
You are not going to get an easier fix.
There was even a thread on this very subject not more than a week ago.....

I have not seen AP mods addressed in this forum, are there any. What say you?
No offense, but you haven't looked very hard then...SC

Well, as I understood it, I backed off the adjusting screw until there was no more free play in the link lever or the push rod link lever assembly. This meant that the adjusting screw was just touching the link lever. This also meant that the AP was at the bottom of its stroke w/ nothing to pump.
As I twisted the throttle, there was no visible squirt of fuel. After reassembly & try out, the bogg was terrible. Taking a WAG, I turned in on the screw 1 1/4 turns and tried again. Much better, "almost' no more bogg.
I have to understand this and I don't. Please offer some direction. Thanks
