FNA CUSTOM CYCLE PARTS FOR VINTAGE HARLEY-DAVIDSON BUILDS

FNA Custom Cycle is a small custom shop out of central Florida that has been building unique bikes since 2009. The product range is tight and deliberate: parts that solve specific problems on vintage Harley-Davidson platforms or add detail-level quality that most off-the-shelf options miss. The Tite Seal intake manifold kit is the flagship with over 60 reviews, and the rest of the lineup covers lighting, carburetor hardware, transmission plates, and cockpit detail parts for Ironhead, Shovelhead, Panhead, and early Evo builds.

TITE SEAL INTAKE MANIFOLD KIT

The most reviewed FNA product in the catalog and the one that put the brand on the map:

• Tite Seal Intake Manifold Kit: Covers 1948 to 1984 Harley Big Twin and Sportster applications. Intake manifold sealing is one of the most persistent issues on vintage Harley motors, where air leaks affect idle quality, carburetor tuning, and overall engine behavior. The Tite Seal kit addresses this directly with a purpose-built solution for the era. Replacement seal kits are also stocked separately for builders who already own the manifold and need to refresh the seals.

LIGHTING AND HEADLIGHT MOUNTS

FNA makes a range of vintage-influenced headlights for builders who want LED output in a period-correct profile:

• Pancake Headlights: Available in 3.25-inch and 2-3/4-inch diameters with clear lens and LED internals. The flat, minimalist profile suits chopper and bobber builds where a traditional round headlight reads too large for the stance of the bike.

• Far-E Headlights: The FNA Far-E is a slightly larger format headlight in clear lens. The Mini Far-E comes in three lens options: clear, amber, and smoke. The amber lens suits period-correct builds where a warm tint reads more authentic than a cold white LED output.

• Dual Headlight Mounts: Stainless steel dual headlight mounts in short and long configurations for builders running two headlights. Both lengths are stocked. Check product listing dimensions against your front end and headlight sizes before ordering.

ENGINE AND DETAIL HARDWARE

• Carb Arm Support Bracket: For Harley-Davidson Ironheads and Shovelheads. The carburetor arm is a persistent weak point on these motors, and the FNA bracket provides a solid support solution. Available in tumbled and polished finish to match the surface direction of the build.

• Pop Top Oil Pressure Indicator: A machined oil pressure monitoring component for vintage Big Twin builds where the oil pressure gauge setup needs a clean, purpose-built solution rather than a generic sender.

• Goodone Cast Aluminum Magneto Cover: Cast aluminum magneto cover for vintage Big Twin applications running a magneto ignition. The cast profile suits builds where a clean, integrated look at the magneto is part of the visual direction.

• Twisty Transmission Plate: For Harley-Davidson Big Twin 4-speed applications.

• Spark Plug Wire Kits: Available in multiple colorways including Blue Explosion, Brown/Yellow/Orange, Ice, and Pink/Purple. For builders who want visible spark plug wires with a distinctive color rather than standard black.
