“Hydraulic clutch has no adjustment and my particular clutch is all the way at the very end appears it may even be slipping some less than 500 miles on the machine and clutch has to be what appears to be 1/8 inch from the end before it catches and no friction zone has almost gotten me hit more than once due to no take up before release and with clutch so far hand has slipped from clutch handle more than once.

NHTSA complaint #10946903, filed 2017-01, 300 miles

“Vehicle looses transmission fluid. 3 trips to the dealership and has not been resolved and continues to do it. Safety issue as once the transmission runs out of oil it may lock up and cause an accident, due to being unable to control the vehicle.”

This is potential safety issue that could lead to a catastrophic accident if this occurs at higher speeds. Bike has only 2500 miles on it and should not be doing this. No acknowledgement from the dealer.”

Inadequate oil volume in the transmission can result in transmission damage/failure that could result in catastrophic consequences for the rider (I.e. A crash). Harley-davidson states in the owner's manual for the motorcycle 'do not overfill the primary chaincase with lubricant. …”
