4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Following 2017–2018 107 models, the 2019–2024 FLHTK featured the Twin-Cooled M8 114 and Boom! Box GTS before being succeeded in 2025 by the redesigned Street Glide Ultra 117.
Oil & Clutch Mechanical Engineering Note
Built for two-up summer touring, the FLHTK combines Twin-Cooled liquid exhaust-head jackets with 4.7 L of SAE 20W-50 engine oil; heavy-duty 80W-140 gear oil quiets the 6-speed gearbox.
Garage Wrenching Gotchas
- Popping off the right lower-fairing painted access door exposes the coolant bottle and pressure cap; never uncap hot, and top up strictly with silicate-free H-D Extended Life OAT coolant.
- On factory-lowered FLHTKL variants, reduced ground clearance makes it easy to scrape the exhaust crossover or cast oil pan on lift ramps without low-profile frame blocks.
5. Frequently Asked Questions (FAQ)
How are engine and separate drivetrain fluid capacities split on the Harley-Davidson Ultra Limited 114 (FLHTK 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 Ultra Limited 114 (FLHTK 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 Ultra Limited 114 (FLHTK 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 740 mm (29.1 in) at 416 kg wet weight, delivering ~361 km per 22.7 L tank.
