pasohlavky - Faragula fichtl

Product overview (what’s being reviewed)

The video reviews a custom motorcycle project: Max Faragula’s modified “Mustang”, built for endurance-style racing, with a special focus on 12-hour races. The bike is positioned as a high-performance build that also emphasizes reliability and parts availability through a collaboration with Motomax (Max is presented as a partner/collaborator with Motomax).

Key features mentioned

12-hour race setup concept

• The bike’s frame and engine are described as originating from a “12-hour race type.”
• Engine swapping is planned for different exhibitions/races, with different engine configurations for non-12-hour events.

Minimal cockpit instrumentation

• Uses a tachometer, but notably no hour meter/clock (called out as a disappointment).
• Includes a shutdown box/switch and a speedometer.

Controls and parts approach

• The builder highlights “new” controls that are minimalist and functional.

Motomax-sourced components

• Many components are said to be assembled using Motomax-produced parts, including items such as:
  • frame
  • wheels
  • tank
  • tenders
• Claimed advantage: riders/owners can later buy the same parts directly from Motomax.

Reinforced chassis

• Rear suspension: described as an original replica, not specially tuned.
• Front: reinforced.
• Frame under the tank: reinforced to prevent waving/twisting on a kart track, especially under long-duration and high-load cornering forces.

Race-dependent gearing

• The gearing setup is changed based on track requirements (balancing slow vs. high-speed needs).
• For 12-hour racing, the “stopper” must have 55 teeth; the discussion also references a 70/55 tooth style concept.
• Example behavior described:
  • One ratio provides strong bottom-end (better acceleration/drive-out).
  • Another emphasizes top-end characteristics but may reduce bottom-end strength.

High-rev cylinder strategy

• The project emphasizes building/repairing a cylinder capable of handling high RPM reliably.
• Claimed stable high RPM: ~11,000 RPM.
• The speaker frames high-RPM reliability as more than simply “repairing and hoping,” noting that pushing RPM introduces problems that must be addressed.

Exhaust tuning as a major performance lever

• The speaker claims exhaust work drives about ~80% of performance.
• Approach:
  • Uses stainless steel exhaust/elbow
  • Switches exhausts to observe quick differences (e.g., on a brake/dyno)
• Theory/engineering basis is emphasized:
  • Shorter vs. longer exhaust affects RPM behavior (shorter often supports spinning more / better midrange/top; longer can support stronger bottom-end).
  • Not framed as purely trial-and-error—some aspects are said to be calculated.
• Performance is described as producing different “spectrums,” such as:
  • Wider usable range vs. a narrow peak-focused band (with references around 10,000 RPM and a general “eight to 10” style range description).

Engine durability and supporting components

• If revs increase, supporting components may require updates; however, the speaker claims the mounting/bearing setup can handle it.
• Bearing-related note: instead of relying on a bronze bushing, the build uses a bearing (positioned as a practical evolution of the original design approach).

Clutch and transmission handling

• Mentions gearbox/clutch adjustments.
• Clutch concept uses the original concept plus upgrades:
  • pressure plate upgrades (including a Simpson part referenced)
  • increased circumferential strength
  • a changed springs approach (described as not using springs in the usual way)

Pros (as implied by the video)

Proven endurance success

• The build’s first race is described as a win, with a ~20-lap lead over second place.
• The setup is presented as not only fast but durable enough that it didn’t break down and the team “kept going.”

Strong reliability under time pressure

• The motorcycle reportedly arrived for the event in a “completely dilapidated” condition about two weeks before the show/races, yet was repaired in time.
• Reliability claims include working immediately after repairs and holding up even after a 12-hour trip (with no issues reported the next day).

Performance that can be tested and repeated

• Exhaust changes are described as producing immediate results on a brake/dyno.
• Exhaust selection is framed around targeting specific performance bands (wider range vs peak-focused behavior).

Parts ecosystem

• Because many parts are Motomax-based, others can potentially source the same components rather than reinventing everything.

Cons / criticisms mentioned

• No hour meter/clock
  • The lack of an hour meter is explicitly called a “letdown”.
• Limited/older-style instrumentation
  • The bike is described as functional but intentionally not “feature-rich” in the gauge cluster.

Comparisons made

Against typical teams

• The host contrasts Max’s approach with “the vast majority of teams” that abandon projects or don’t finish.

Against generic exhaust tuning

• The exhaust strategy is contrasted with the idea that some people approach tuning as pure trial-and-error.
• Max’s position is that there is knowledge/calculation behind the decisions (though the full exact method isn’t fully detailed).

---

Ratings / numbers explicitly mentioned

• Cylinder/engine RPM claim: about 11,000 RPM
• Exhaust impact claim: exhaust tuning contributes ~80% of performance
• Race lead: ~20 laps
• 12-hour gearing requirement: 55 teeth for the “stopper”
• Other gearing reference: a 70 vs 55 tooth setup is discussed
• Exhaust performance references:
  • behavior around 10,000 RPM
  • a “wider usable spectrum” described in general terms (e.g., “from eight to 10”)

---

User experience / how it feels to ride (as described)

• The motorcycle is configured to handle kart track cornering forces through chassis reinforcement.
• It’s set up so key variables can be matched to the event, including:
  • gearing
  • engine behavior
  • exhaust characteristics
• Reliability is repeatedly emphasized as part of the rider experience: finish the race, and finish strong.

• Host / Biker Boys Garage (voiceover + questions)

  • Focuses on instrumentation (hour meter), parts sourcing, gearing rules, reinforcement logic, and theory behind cylinder/exhaust choices.
  • Emphasizes context that most teams don’t finish.

• Max Faragula (builder/rider)

Concise verdict / recommendation

The video presents the Mustang build as a high-RPM but endurance-reliable custom motorcycle, with exhaust tuning and mechanical reinforcement identified as major performance drivers. The main drawback mentioned is the missing hour meter/clock. Based on the reported endurance results (a win with a large lead and strong reliability after urgent repairs), the overall recommendation is yes—it appears to be a well-engineered endurance-focused custom, particularly for riders who want measurable tuning and parts availability via Motomax.
