II. Overview of the Project

A. What is a racing lawn mower?

A racing lawn mower, in this context, refers to a go-kart-like vehicle that uses a vintage lawn mower hood for its design. It’s essentially a modified go-kart powered by a Suzuki GS450 6-speed motorcycle engine. The builders of this project aim to create a high-performance vehicle that is both fun to drive and visually appealing.

B. Using a Suzuki GS450 6-Speed Motorcycle Engine

The centerpiece of this racing lawn mower project is the Suzuki GS450 6-speed motorcycle engine. This engine provides the power and performance necessary to turn the lawn mower into a thrilling ride. The builders have sourced this engine for a reasonable price and plan to install it in their modified go-kart.

C. The goal of the project

The goal of this project is to create a racing lawn mower that can be showcased at the paint swap meet at Texas Motor Speedway. The builders aim to complete the project in time for the event and impress the crowd with their unique creation. This project serves as an opportunity for the builders to showcase their skills and creativity in the realm of vehicle customization.

D. Parts used from Go Power Sports

Go Power Sports, a reputable supplier of go-kart and small engine parts, has provided various components for this project. These parts include wheels, brake rotors, a live axle kit, and tie rods. The builders are excited to showcase the quality and performance of these Go Power Sports parts in their racing lawn mower.

III. Building the Frame

A. Bending tubing for the frame rails

The first step in building the racing lawn mower involves bending tubing for the frame rails. The builders use a tubing bender to shape the metal tubing according to their desired specifications. By carefully bending the tubing, they create a sturdy frame that will provide support for the rest of the vehicle’s components.

B. Welding the frame together

Once the tubing is bent, the builders proceed to weld the frame rails together. Welding ensures that the frame is strong and rigid, capable of withstanding the forces exerted during high-speed maneuvers. The builders take their time to ensure precise and secure welds for maximum strength and safety.

C. Fabricating engine mounts

To securely install the Suzuki GS450 engine, the builders fabricate custom engine mounts. These mounts provide a stable foundation for the engine, preventing it from shifting or vibrating excessively during operation. By fabricating the mounts to fit the specific dimensions of the engine, the builders ensure a snug and secure fit.

D. Installing gussets

To reinforce the frame and improve its structural integrity, the builders install gussets. Gussets are metal plates that are welded at the corners of the frame to provide additional strength and support. The builders utilize a crossfire Pro to cut out the gussets and tabs needed for the steering system, ensuring a precise fit and optimal performance.

IV. Installing the Axle and Steering

A. Hanging the live axle

Once the frame is complete, the builders proceed to install the live axle. The live axle is responsible for transferring power from the engine to the rear wheels. By properly hanging the live axle, the builders ensure that it is securely attached to the frame and aligned correctly for optimal performance.

B. Mounting the tires

To complete the rear wheels, the builders mount the tires onto the rims. They demonstrate a method of tire installation without the use of tire soap, utilizing the working side of the rim for easier installation. By carefully following the step-by-step process, the builders successfully mount the tires onto the rims, ensuring a secure fit.

C. Creating bearing hangers

In order to support the live axle and allow it to rotate smoothly, the builders create bearing hangers. These hangers hold the axle bearings in place, ensuring proper alignment and reducing friction. By fabricating the hangers themselves, the builders have full control over the design and fit, resulting in a precise and reliable bearing system.

D. Adding nerf bars

To enhance the aesthetics and safety of the racing lawn mower, the builders install nerf bars. These bars are attached to the sides of the vehicle and provide protection against impacts. The builders take pride in fabricating the nerf bars themselves, ensuring a custom fit and a visually appealing design.

E. Issues with the steering linkage

During the installation of the steering system, the builders encounter some challenges with the steering linkage. They address these issues by carefully adjusting the positioning of the linkage components and ensuring proper alignment. By troubleshooting and making necessary adjustments, the builders overcome these obstacles and successfully install the steering system.

F. Challenges with the carburetor linkage

In addition to the steering linkage, the builders also face challenges with the carburetor linkage. They encounter difficulties in ensuring smooth and consistent throttle response. To resolve these issues, the builders focus on adjusting the carburetor linkage and fine-tuning the throttle mechanism. By carefully addressing these challenges, they ensure optimal engine performance and control.

G. Installing the steering stop

To prevent the steering system from over-rotating and causing damage, the builders install a steering stop. This stop acts as a physical barrier that limits the range of motion of the steering wheel. By strategically positioning the steering stop, the builders ensure safe and reliable steering control.

H. Adjusting the tie rod

To achieve proper alignment and handling, the builders adjust the tie rod. The tie rod connects the steering system to the front wheels, allowing for precise control and responsiveness. The builders carefully measure and adjust the tie rod to ensure the wheels are aligned correctly and the steering is dialed in for optimal performance.

V. Wiring and Engine Components

A. Checklist of tasks

Before moving on to the wiring and engine components, the builders create a checklist of tasks to complete. This ensures that all necessary steps are covered and nothing is overlooked. By following a structured checklist, they can stay organized and ensure that each aspect of the project is properly addressed.

B. Focusing on wiring

With the checklist in hand, the builders focus on the wiring of the racing lawn mower. They carefully route and connect the various electrical components, including lights, ignition system, and switches. By following a systematic approach and paying attention to detail, they create a clean and functional wiring system.

C. Getting spark for the engine

In order to start the engine, the builders troubleshoot and ensure that there is a spark. They identify any potential issues with the ignition system and make the necessary adjustments to ensure proper spark delivery. By addressing these issues, they can ensure the engine starts reliably and runs smoothly.

D. Discovering oil leaks

During the initial test run, the builders discover oil leaks in the engine. They inspect the engine components, identify the source of the leaks, and plan to replace a seal to fix the issue. By carefully addressing these leaks, they prevent further damage and ensure the engine remains in good working condition.

E. Temporary fix for fuel tank issue

In the midst of the build, the builders encounter a fuel tank issue. They devise a temporary fix to resolve the problem and ensure the engine receives a consistent fuel supply. While the temporary fix may not be a permanent solution, it allows them to continue working on other aspects of the build without interruptions.

F. Working on the floor pans

To complete the interior of the racing lawn mower, the builders work on the floor pans. They ensure that the floor pans are securely mounted and provide a comfortable and functional space for the driver. By paying attention to the small details, they create a well-designed and user-friendly interior.

G. Adjusting the throttle, brakes, and clutch

In preparation for the test run, the builders focus on adjusting the throttle, brakes, and clutch. These components are crucial for optimal control and performance. By carefully fine-tuning these mechanisms, the builders ensure that the racing lawn mower is responsive and safe to operate.

VI. Challenges and Test Run
