My bike has the pea shooter, the snorkel and the throttle stop removed and no change to the ecu.
I did not over oil the filter. Give it a try, it seemed to slove my problem.
In any event, good luck

I thing it may be due to the throttle blade being on a 22 degree angle in the closed position or at idle.
A small input from twisting the throttle lets a large amount of air in and if you need to leave off quickly for some reason you have too much air in the cylinder and not enough fuel so the motor died. Just like when the accelerator pump is not working correctly.
I talked to a friend who has a 2010 YZ450 who had the same problem till he had hie throttle body reworked by Injectioneering. That may be my fix also.

Good to hear you got it figured out. Nothing's worse than having a great bike that doesn't quite run correctly!
