05 trx bog

[chuck127]

I've tried to ask this before, but with no real answers, but I have a bog on my 05 trx 450. It is a Baldwin motor. It has a 14:1 piston, Baldwin MX cam, CRF 43.5 mm carb, Baldwin exhaust. The quad was actually Josh Williams pro-am Quad. It boggs mostly on the face of choppy of kinked jumps where you are on and off the throttle. I've been riding for many years and know how to ride/jump. I have a complete new motor and completely rebuilt carb and the bog remains. I have tried various jetting specs to no avail. Any help would be appreciated.
Thanks, Chuck.
