Fxr-Division #469

A soft-tail motor refers to installing an engine from Harley-Davidson’s Softail line into a different platform. In custom FXR builds, this swap is used to get a different engine character and parts compatibility, but it also adds fabrication and setup work.

A mono shock is a rear suspension setup that uses a single shock absorber, typically mounted centrally, instead of twin shocks. On bikes like an FXR, switching to a mono shock is a common custom upgrade that changes ride feel and the look of the rear end.

“Seat and exhaust” refers to two of the most common early customization categories on motorcycles: rider comfort/ergonomics (the seat) and engine sound/flow (the exhaust). The host is emphasizing that even basic-looking upgrades can quickly add thousands of dollars to an FXR build budget.

“Baseline” here means returning the bike to a known-good, standard operating condition by addressing the key wear items and system health issues. The hosts argue that spending money up front to reach that baseline is what makes the FXR “pretty reliable” afterward.

The charging system is the motorcycle’s electrical system that generates power while the engine is running and keeps the battery charged. If it fails, the bike may start poorly or die while riding, which is why the hosts list it as a key “baseline” item on an FXR.

The battery stores electrical energy and powers the motorcycle’s electronics and starter. In this segment, they treat the battery as part of the “baseline” refresh—because if the charging system is bad, a new battery may not solve the underlying issue.

Brake fluid is the hydraulic fluid that transfers force from the brake lever/pedal to the brake calipers. If it’s old, contaminated, or low, braking performance can degrade—so the hosts include it as part of getting an FXR back to baseline reliability.

Starter fluid is a volatile spray used to help an engine start when it’s hard to crank. The host is describing a risky “quick fix” mindset—using starter fluid instead of diagnosing the real problem (like the charging system or other failures).

“Rolling the dice” is a metaphor for taking a risk when you don’t know the full condition or history of a vehicle. In this context, it’s about buying or riding an FXR without confirming the health of critical systems (charging, clutch, brakes).

Clutches are the friction components that connect and disconnect engine power to the transmission (on a motorcycle, typically the hand-operated wet clutch). The host lists clutch failure as one of the “you don’t know what you’re buying” risks on an FXR with unknown history.

This describes a full teardown restoration approach: disassembling the motorcycle down to the frame and redoing systems so the bike is reliable for the long term. The host contrasts this with “quick fixes,” implying that deep work is sometimes necessary when the bike’s history is messy.

“Garage” is used as a storage location for an older motorcycle that’s been parked for years. The segment’s theme is that these bikes can sit unused and later be revived, which matters for how owners think about long-term ownership and restoration.

In this context, “parts” refers to replacement components used to restore an older motorcycle back into working condition. The hosts mention customers calling for parts to “bring them back to life,” implying a restoration/maintenance workflow rather than routine wear items.

A T sport fairing is an aftermarket or model-specific front bodywork piece that covers airflow around the front of the motorcycle. Fairings can improve aerodynamics and stability, and in this context it’s being used as part of a front-end conversion on an FXR.

A full T sport front means swapping the entire front-end assembly (not just one cosmetic piece) to the T sport configuration. This typically includes the fairing and related front components so the bike’s look and airflow characteristics match the T sport setup.

Horsepower is a measure of engine power output, often used to describe how strongly a motorcycle can accelerate. In this segment, they’re emphasizing that you can add a lot of horsepower to the FXR platform without the bike’s structure causing problems.

Motor mounts are the brackets and isolators that secure the engine to the motorcycle’s frame. If the chassis flexes too much under power, motor mounts can be stressed, leading to cracking, tearing, or misalignment.

The chassis is the motorcycle’s main structural framework that supports the engine, rider, and suspension components. Here, they’re arguing the FXR chassis can tolerate high power without excessive flexing that leads to other mechanical issues.

The master cylinder is the hydraulic “pump” that turns your brake pedal force into pressurized brake fluid. That pressure is what moves the calipers or wheel cylinders to clamp the brakes.

Miles per hour (mph) is a speed unit used to describe how fast a vehicle is traveling. In performance discussions, it helps translate engine power and gearing into real-world cruising capability.

“Fuel injection” is the system that delivers fuel to the engine using electronically controlled injectors instead of a carburetor. Switching back into fuel injection typically means you can tune fueling more precisely for ride conditions and modifications.

A Thundermax tuner is an aftermarket engine control module/tuning device used on motorcycles to adjust fuel and ignition behavior. The goal is to improve throttle response and overall power by matching the tune to the bike’s current setup and future modifications.

A dyno (dynamometer) is a machine that measures engine output like horsepower and torque while the bike is under load. Tuners often use dyno sessions to dial in the fuel/ignition settings so the bike performs correctly across the rev range.

The Sturgis motorcycle rally is a major annual event in South Dakota where riders and aftermarket vendors gather. In this segment, it’s where the Thundermax team plans to install tuners on-site.

Black Hills Harley-Davidson is a dealership location mentioned as the on-site setup point during the Sturgis rally. The context is vendor support—installing Thundermax tuners in person.

RNS motorcycles is referenced as a custom-building brand/dealer offering “boldest customs.” In this segment, it’s positioned as the place to go if you want a motorcycle upgrade focused on style, performance, and quality.

An air cleaner (intake filter) controls how air flows into the engine. “Big sucker” style air cleaners typically refer to larger, more free-flowing intake setups that can change airflow and engine sound/response.

Kabuto is a Japanese helmet brand known for motorsport-focused designs and safety engineering. In this segment, the host highlights Kabuto’s helmet tech and aerodynamics aimed at high-speed stability.

A Crest Spoiler is an aerodynamic appendage on the helmet designed to influence airflow and reduce lift or buffeting. It’s meant to help the helmet stay steady at high speeds.

MIPS (Multi-directional Impact Protection System) is a helmet safety system designed to reduce rotational forces during certain impacts. It uses a low-friction layer so the helmet can move slightly relative to the head.

ACT tech refers to a specific helmet construction technology used by Kabuto. It’s intended to improve impact performance by managing how forces are absorbed and distributed in a crash.

“Triple digit speeds” is a casual way to say speeds above 100 mph (or 160 km/h). In helmet marketing, it emphasizes that the aerodynamic features are meant to keep the helmet stable and reduce wind buffeting at very high velocity.

A full-face helmet covers the entire head, including the chin bar, which offers more protection than open-face designs. “MotoGP race helmet” implies a track-oriented design focused on high-speed aerodynamics, stability, and impact protection.

This is a segment marker indicating the discussion is shifting to the FXR platform. It signals that the hosts are about to talk about that specific motorcycle family’s background and purpose.

“Canyon passes” are winding mountain roads with lots of elevation change and tight curves. They’re a common test route for motorcycle handling because they demand braking, cornering grip, and stability over and over.

“Drag a knee” is a riding technique where the rider intentionally lets a knee touch the ground while cornering. It’s a sign the bike is leaned over far enough that the rider is using the available cornering clearance and grip.

Fairings are aerodynamic body panels that reduce wind drag and turbulence around the rider and bike. In this segment, the host emphasizes that fairings “break up the wind,” which matters for long-distance comfort and stability at speed.

“Shovel head” refers to Harley-Davidson’s Shovelhead V-twin engine generation (notably used in many FXR-era and custom builds). “Big inch” means a larger-displacement version of that engine, typically built for stronger torque and highway pull.

“Generator shovel” describes a Shovelhead configuration that uses a generator-style charging setup (as opposed to later alternator-based systems). It’s mentioned here as part of the builder’s engine lineup for higher-displacement “big inch” builds.

“Evo” is shorthand for Harley-Davidson’s Evolution (EVO) V-twin engine generation. “Big inch” Evo means a larger-displacement build of that engine, aimed at matching or exceeding the torque and acceleration of other big-displacement Harley platforms.

“M8” refers to Harley-Davidson’s Milwaukee-Eight engine family. Calling it “stock” means the engine is in factory configuration, used here as a benchmark for how well the custom “big inch” builds can keep up.

“Performance baggers” refers to touring motorcycles (often based on Harley-Davidson-style bagger platforms) that are modified for stronger acceleration, handling, and overall speed compared with stock touring bikes. The “bagger” part typically means the bike has saddlebags and is set up for long-distance riding.

“Road Glides” refers to the Harley-Davidson Road Glide line, a touring motorcycle known for its comfortable ride and fairing/wind protection. In this context, the speaker is saying that owning two very similar touring bikes (two Road Glides) doesn’t offer much variety in riding experience.

“Evo” is shorthand for Harley-Davidson’s Evolution engine family (often called the “Evo” motor). “Five speed” indicates the transmission has five gears, which affects how the bike feels at different speeds and cruising RPM.

A sport bike drivetrain refers to the powertrain components that deliver engine output to the rear wheel—typically including the transmission and final drive. The hosts use it to describe a crossover bike that pairs cruiser styling/ergonomics with sport-bike performance hardware.

A cruiser bike is a motorcycle style built around relaxed riding posture, comfortable ergonomics, and often a heavier, more laid-back feel. Here it’s contrasted with sport-bike components to describe a crossover personality.

“FXR aesthetic” means building or choosing a motorcycle to visually match the Harley-Davidson FXR’s signature look. In enthusiast talk, this often implies styling-focused upgrades (like bodywork, stance, and trim) rather than changing the bike’s core mechanical design.

“Bells and whistles” is a common phrase meaning extra features or upgrades beyond the basic version. Here, it’s used to describe an FXR-style bike that includes more than just the core look—additional convenience, comfort, or styling details.

“Pan America” refers to Harley-Davidson’s adventure-touring motorcycle line, known for being built as a more road-capable, long-distance bike than a typical cruiser. In this segment, the hosts contrast it with a different motorcycle that’s more sport-bike-like, highlighting how engine character changes the ride feel.

RPM (revolutions per minute) is how fast the engine spins. The segment contrasts bikes that run best at higher RPM with Harleys that make their character from lower-end torque.

Torque is the engine’s twisting force that tends to move the bike strongly from low speed. The speaker says Harley-Davidson engines deliver that low-end torque feel, which is why they “pull” even when you’re not revving as high.

“Twin” refers to a motorcycle engine with two cylinders. The speaker’s “Turkey, big twin shit” is describing a big-twin Harley-style engine character—typically meaning a V-twin with a distinct low- to mid-range feel and sound.

In motorcycle talk, “chop” usually describes a rougher, uneven exhaust/engine sound and vibration—often associated with certain cam profiles, exhaust setups, or engine configurations. Here it’s paired with “grunt” to emphasize the audible and tactile character of the older/big-twin setup.

“Taller bars” means handlebars mounted higher than stock, which changes rider posture and leverage. In this context, it’s part of the seating/ergonomics differences the speaker says make the FXR feel less like a pure sport bike and more like a comfortable blend.

A “skid mark” is a dark streak left when a tire slides across the road surface instead of rolling normally. The speaker uses it as a vivid indicator that their bike riding involves enough traction loss or aggressive maneuvers to leave marks.

This is describing aerodynamic airflow effects at speed: as speed increases, wind pressure rises and can cause the rider’s face and facial hair to be pushed around. On motorcycles, this can strongly affect comfort and visibility, especially at highway speeds.

A “six speed” refers to a motorcycle’s transmission with six forward gears. Gear count affects how the bike’s engine speed (RPM) stays in the power band at different road speeds, which can change comfort and how well the bike keeps up in traffic.

“Gas stops” refers to planned fuel stops during a ride. In group riding, the frequency of gas stops affects pacing and how long the ride takes, especially if the bike’s fuel range is limited.

“No suspension” describes a motorcycle setup with little to no shock-absorbing travel. That makes the ride harsh and can reduce control and comfort over bumps, which is why the speaker emphasizes how limited the range and practicality felt.

“Kick only” means the motorcycle is started using a kick starter rather than an electric starter motor. It’s more old-school and can be less convenient, especially when the bike is cold or the starter system is temperamental.

A “four-speed” motorcycle has a gearbox with four forward gear ratios. Fewer gears usually means less flexibility for keeping the engine in its best power band, especially at highway speeds.

“Tib Fib” is shorthand for the tibia and fibula, the two bones in the lower leg. A “compound fracture” means the bone broke and the injury involved an open wound, which can raise the risk of infection.

“Hardware installed” refers to surgical implants used to stabilize a fracture, such as plates and screws. In the context of infections, the speaker’s later mention of removing and reinstalling hardware highlights how complicated recovery can become.

“Fluids” is a general term for the liquids that keep a motorcycle running—like oil, coolant, and fuel system-related fluids. Changing them refreshes lubrication and cooling and can help prevent wear or overheating.

A kickstart is a manual starting method where you use a lever to spin the engine until it catches. It’s common on many motorcycles and is especially useful when a battery is weak or the bike hasn’t been run in a while.

A carburetor is the fuel-mixing device on many older motorcycles and cars that combines air and fuel before it enters the engine. It can be sensitive to sitting unused, so a “brand new carburetor” often improves starting and throttle response.

An open-face helmet (often called a “3/4” helmet) covers the top and sides of the head but leaves the face exposed. Riders often choose it for airflow and comfort, but it provides less facial protection than a full-face helmet.

A swing arm is the pivoting arm that carries the rear wheel on many motorcycles. When the swing arm “flops around,” it usually means there’s excessive play or looseness at its pivot or related mounting points.

Transmission is the gearbox that transfers power from the engine to the rear wheel through different gear ratios. In a custom build, how the transmission is mounted can influence drivetrain alignment and how other parts like the swing arm behave.

Push-button start is an ignition system that starts the engine electronically with a button rather than using a traditional key/lever starter. On custom bikes, it’s often added to make the bike easier to use day-to-day.

“Pans” is shorthand in Harley custom talk for the Panhead engine family. Panhead refers to an older Harley V-twin design, and the speaker groups it with other classic Harley engine nicknames.

“Shovel heads” is shorthand for Harley-Davidson’s Shovelhead engine family. It’s a classic air-cooled V-twin era nickname, and here it’s used to describe the type of older bikes the group was riding.

ABS stands for anti-lock braking system. It prevents the wheels from locking up during hard braking, helping the rider keep steering control and reduce skids.

A power slide is a controlled oversteer maneuver where the rider intentionally breaks traction at the rear and keeps the slide going using throttle and steering. On motorcycles, it’s often done in a way that emphasizes rear-wheel slip rather than front-brake stability.

“Rear brake only” means braking using only the rear wheel’s brake rather than both front and rear. On motorcycles, relying on the rear brake can change stability and traction behavior compared with using the front brake.

“TwinCamp swap” appears to refer to a specific conversion or parts swap on a motorcycle platform, likely involving twin-cam components. The speaker connects it to using the shop’s service to make controls and get parts ready for modern bikes.

The “pivot thing from the front” sounds like a specific front-end hardware component being removed as part of the build. Without the exact part name, it’s best understood as a front-end linkage/assembly that affects how the bike’s front end behaves.

A steering stabilizer is a device (often a hydraulic damper) that resists handlebar oscillation. On motorcycles, it can reduce wobble and improve confidence when the bike is loaded, accelerating, or encountering uneven pavement.

Arnell is referenced as the source of a kit used for the speaker’s FXR setup. In this context, it’s likely an aftermarket supplier providing parts that change how the motorcycle’s front-end components are mounted or configured.

Some kickstand designs use two springs to provide the correct return force and damping for the stand’s motion. If someone swaps in the wrong spring setup (or loses one), the kickstand can end up too loose or not return properly.

A secondary arm is an additional lever/pivot piece in the kickstand mechanism that works with the springs to control motion. It helps determine how the stand engages and how the spring tension is applied.

A lug in this context is a small protrusion/feature that locates or applies tension to a spring in the kickstand assembly. If the lug is missing or the spring is mis-routed, the kickstand can lose proper tension and become floppy.

A “frame swap” in this context means replacing or reworking the motorcycle’s chassis/frame to accommodate an M8 engine conversion. Because the engine and mounting points differ from earlier setups, it’s typically a fabrication-heavy job with more complexity than a straightforward engine swap.

A “twin cam swap” refers to converting a Harley-Davidson to a Twin Cam engine configuration (a different engine generation than the Milwaukee-Eight). The speaker contrasts the M8 conversion with a Twin Cam swap to emphasize that the M8 work is more involved and not as straightforward.

“M8, combination” is used as shorthand for the specific pairing of an M8 engine with an FXR build. The key point is that the conversion isn’t one-size-fits-all—different bikes and parts combinations lead to different fabrication and setup requirements.

Sheet metal refers to thin metal stock used for body panels, brackets, and fabricated plates. In this context, the speaker is arguing that a universal pre-cut plate isn’t worth it because you can buy sheet metal and cut it to fit each frame.

A paper template is a pattern you cut out to match a specific part’s shape before you cut the real metal. In fabrication, it helps you transfer measurements from the vehicle/frame to the sheet metal so the final piece fits correctly.

In a vehicle chassis context, the backbone is the central structural member that ties the car together and carries loads. The speaker mentions layers of tubes and plates inside it, emphasizing how complex it is to cut and fit parts around that structure.

A motor mount is a bracket or bushing that secures the engine to the chassis to control movement and vibrations. The center motor mount is the mount located near the middle of the engine/chassis setup, and it affects how the drivetrain loads the frame.

The top motor mount is the engine mounting point located higher in the chassis/engine bay. The speaker is weighing it against a front mount because components like the throttle body and fuel rail interfere with how the mount and link can be packaged.

A fuel rail is the pressurized metal (or composite) manifold that distributes fuel to the injectors. Because it sits in a specific spot on the engine, it can interfere with mounting hardware and require a different mount/link placement.

The throttle body is the air-control valve assembly that regulates how much air the engine can ingest. In fuel-injection systems, it’s part of the intake path, and its location can affect how other hardware (like mounts/links) can fit.

A stabilizer link connects the suspension’s stabilizer bar (anti-roll bar) to the suspension components. A secondary rear stabilizer link implies an additional or upgraded linkage to increase rear roll control and stability.

A stabilizer bar (also called an anti-roll bar) reduces body roll by transferring load between the left and right suspension. The speaker is describing how additional stabilizer hardware can be bolted in using available space.
