Used Buying Inspection Checklist
What to look for when buying a used 2017 Harley-Davidson FLHTKL Ultra Limited Low.
Transmission Fluid Level
Check if the transmission dipstick is low while the primary is overfilled; this confirms the 'fluid transfer' issue.
Air Cleaner Housing
Check for oil pooling in the air cleaner. This is a primary symptom of 'sumping' where oil is forced out of the breathers.
Clutch Master Cylinder Recall
Verify if the recall for the hydraulic clutch master cylinder (Recall 0173) has been performed, as it can cause the clutch to fail to disengage.
Oil Cooler Line Clamps
Check for signs of oil misting near the front down-tubes; early 2017 models had a recall for improperly installed oil line clamps.
