Question Throttle response

Anyone else notice a bit of a stumble with the throttle response of their XP? Its nothing bad, or unacceptable. But it is there to a small degree. Think of a carb equipped Yamaha WR250. If you know Yamaha's you know exactly what I am talking about. Its not what I would expect from a modern FI system. Granted, mine is only almost through its 1st tank of gas. Maybe it will get better as it breaks in.

Seem like all the 2012 and up 850s do it, since the went with the larger throttle bodies.

my 2011 850 stumbles a bit i think they all do. its not the best intake design for smooth airflow. its inherent when you design something to not let in water and dirt it will slow airflow to..

Also, your belt might be slipping, making it feel like throttle stumble. Happened on my new RZR last year for the first few miles. Wait til the belt breaks in and I bet you won't feel it...

A very large TB explains a lot... and is definitely the probable cause.
