4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Replacing the Road Glide Ultra in 2020, the FLTRK pairs Twin-Cooled M8 114 heads housed in vented lower fairings with a Tour-Pak carrier, heated grips, and an 18-inch Slicer II front wheel.
Oil & Clutch Mechanical Engineering Note
Alongside 3-Hole lubrication, the Twin-Cooled M8 114 circulates OAT coolant through twin lower-fairing radiators via an electric pump; inspect the right lower-fairing bottle regularly.
Garage Wrenching Gotchas
- After draining Twin-Cooled coolant, run the ignition-on throttle-held electric pump bleed routine before starting the engine so trapped air pockets do not overheat the exhaust bridges.
- At 423 kg wet, letting rear pressure drop below 40–42 PSI accelerates cupping and low-speed weave under Tour-Pak load; check cold tire pressures with an angled chuck before trips.
5. Frequently Asked Questions (FAQ)
How are engine and separate drivetrain fluid capacities split on the Harley-Davidson Road Glide Limited 114 (FLTRK Twin-Cooled)?
The engine sump takes 4.3 L drain-only and 4.7 L (4.97 US qt) with filter (HD 62700296 / 62700297 (HF171C)) of SAE 20W-50 (JASO MA2), while isolated drivetrain cavities (primary chaincase 1065 ml, separate gearbox 828 ml) require dedicated gear/chaincase fluid.
How do you accurately check the oil level on the Road Glide Limited 114 (FLTRK Twin-Cooled), and what are its service intervals?
Bring the engine to full operating temperature and check the Full Hot mark with the motorcycle resting on its sidestand (Jiffy Stand) on level pavement—measuring upright leads to crankcase overfill and breather blow-by. Torque the drain plug to 24 N·m with a new crush washer. Factory oil change intervals are every 8,000 km, with valve clearance inspection every 48,000 km.
What are the cold tire pressures, puncture repair type, seat height, and range of the Road Glide Limited 114 (FLTRK Twin-Cooled)?
Fitted with 130/70B18 63H front and 180/55B18 80H rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 36 / 40 PSI (248/276 kPa) solo or 36 / 42 PSI loaded. Seat height is 735 mm (28.9 in) at 423 kg wet weight, delivering ~359 km per 22.7 L tank.
