Hey guys. I ride a 2017.5 1200GS. Recently I've noticed the throttle action is no longer a smooth roll on and off. It feels somewhat sticky--almost crunchy when I subtly make small adjustments. It's a fly-by-wire throttle system so there's no cable involved, right? So I guess there's some dirt/moisture in the throttle mechanism. How do I get it back to being smooth? Thanks.
