Harley Davidson FLSTN Softail Deluxe 2016 Service Manual

Harley's own confirmed dealer copy for this exact model year frames a genuinely long-view design philosophy: "take a look at the horseshoe oil tank adorning our Softail models. It's the same one you'd see on a restored dresser from the '50s, or a radical Panhead chopper from the '70s. And you'll find it right now on future Harley-Davidson models that are still on the drawing board." That's a deliberate design signature Harley has carried across decades of Softail production, and this 2016 Deluxe wears it in genuine period-correct chrome-and-whitewall trim.

Power comes from the High Output Twin Cam 103B, an air-cooled V-twin displacing 1,690cc (103.1 cu in), a 3.87-inch bore and 4.374-inch stroke, a 9.6:1 compression ratio, fed by Electronic Sequential Port Fuel Injection (ESPFI), run through a 34/46-ratio chain primary drive and belt final drive. Orlando Harley-Davidson's own confirmed factory spec sheet lists genuinely precise gear ratios starting at 9.311:1 in first gear, dropping through 6.454:1 in second and 4.793:1 in third.

That same confirmed dealer specification lists a 32.1-degree rake with 5.8 inches of trail on a 64.4-inch wheelbase, a genuinely accessible 24.5-inch laden seat height (26.4 inches unladen), and 4.3 inches of ground clearance. Dennis Kirk's own confirmed parts reference lists MT90HB-16 front and MU85HB-16 rear tires on a 41mm fork, a 133-tooth/24mm drive belt, and a 32/66-tooth front/rear pulley ratio — genuinely the same standard laced-wheel configuration this nameplate has carried since its earliest Twin Cam-era years.

Fuel capacity comes in at 5 gallons with 3.5 quarts of oil (with filter), and shipped weight sits at 701 lbs (730 lbs in running order) per Harley's own confirmed factory documentation. This exact FLSTN configuration ran through 2017 before Harley's comprehensive 2018 Softail platform redesign temporarily dropped the Deluxe from the lineup entirely, eventually reintroducing it years later as the FLDE on the new single-shock, Milwaukee-Eight-powered chassis.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2016 Softail Deluxe FLSTN running the way it was built to.
