Default Slow acceleration engine response
Hi everybody.
I have been looking in your great great forums since months and I have to say that found very useful topics and discussions. So I decided to be part if it if you will allow me to be ofcourse
Riding 2012 Fat Boy Lo and done about 3100 miles and I noticed when in 3rd gear at about 38 MPH and about 2000 rpm when I release the throttle and suddenly pull it full throttle the engine is responding slowly like it is not breathing well or starving for fuel just when reaching 50MPH the engine suddenly response well and acceleration will come sudden and good, like the engine has got what it wanted.

Bike is all standard and stock.
Please help, is this something I should worry about or it is normal and just a new rider thoughts ?

I checked air cleaner, wiring, O2 sensors, throttle cables with throttle butterfly valve and all are seems OK.

Thanks
