When it's still cool in the mornings I thought the vent heat would be a nice option however I seem to be getting little or no air flow (hot or cold) from those lower vents. I've turned the vent knob to the open position and tried setting the little louver arm in either position but I don't seem to get much air at all flow at all. I've never looked into that lower vent area but I assume there must be some internal piping that directs the warm air through the vent? If anyone has it working on their bike I'd appreciate an update on what to expect and how to set the louvers. Thanks.
