I would like to know more about this feature . I haven't seen any posts or threads on this feature . I've heard it makes trike sound like a tractor at idle . I'm looking for feedback from those that use it when stopped. *I would think this would help a lot with heat build up when doing the sturgis shuffle . I know this is not new to recent bike models , but coming from 03 roadking , it will be a new feature for me . how well does it work??*
