Okay, my bike does not have this problem. For those few owners that have experienced this...have you tried adjusting your throttle cables to take the slack out of the throttle ????

I found that my throttle cables had more slack that I was used to on a GL-1800 platform. I adjusted my cables to remove said slack, and it is very responsive, no throttle hesitation, etc.

Just something to check, before going to the dealer.

But...I also warm my bike up for a minute or more before riding.
