"All stock 450's have a stumble at the bottom that is the direct result of too much fuel being dumped in to the venturi by the accelerator pump. Under the plastic cover on the right side of the carb there is an adjuster that positions the cam that works the pump. A half turn clockwise will make your 450 a new bike."
I did it and it took care of the stumble right off idle. My bike accelerates hard right off of idle now with no hesitation.
