It’s a significant step in transforming your Ruckus from a standard scooter into a unique expression of your personal style. This upgrade signals a commitment to enhancing both performance and aesthetics. It’s the foundation upon which you can build a truly one-of-a-kind machine. Combined with other aftermarket parts such as exhaust systems, custom bodywork, and unique paint schemes, the possibilities are endless.
Performance Boost Compared to Stock
The difference is palpable. The stock Ruckus is a fantastic platform for a stylish commuter or light pleasure riding. After installing a big bore kit, it becomes an altogether different beast, a machine that feels far more lively and capable. It’s a transformation that truly makes the Ruckus feel like a new scooter.
Key Considerations Before You Purchase
Engine Compatibility
Not all big bore kits are created equal, and it’s essential to ensure that the kit you choose is specifically designed for your Ruckus’s engine. Honda has used several different engine configurations over the years. Most modern Ruckus scooters use the GET (Global Engine Technology) engine. Verify the engine type before purchasing any parts. Failing to do so can lead to a lot of headaches and wasted money.
Kit Components
The composition of a big bore kit typically involves a number of crucial components that work together to dramatically increase engine performance. You will typically find the cylinder, which is the core component where the combustion process takes place. The piston and rings, which create a seal within the cylinder, ensuring proper compression. You might find the cylinder head, although this can be an optional inclusion, depending on the kit. The cylinder head is where the intake and exhaust ports are located and where the spark plug screws in. And of course, various gaskets and other necessary hardware are included to ensure a proper seal and secure fit. Carefully review the kit’s contents to make sure you are aware of what you will be receiving.
Skill Level and Tools Needed
The next crucial factor is to evaluate your own skill level and the tools needed. Installing a big bore kit isn’t rocket science, but it does require a degree of mechanical aptitude and access to the correct tools. You will need sockets, wrenches, torque wrenches, and other specialized tools. Be honest with yourself. If you’re not comfortable working on engines, professional installation may be the best option to guarantee a proper and trouble-free installation. This will also save you time and reduce the chances of making costly mistakes.
Supporting Modifications
Many big bore kits work best when used in conjunction with supporting modifications. These include an upgraded fuel system to deliver the extra fuel needed by the larger engine. Many owners opt to upgrade to a larger carburetor, while those looking for the ultimate control may install a fuel injection system. Other modifications include an exhaust system, to help manage the increased exhaust flow. An aftermarket exhaust not only boosts power but also adds a custom aesthetic. An intake system, such as a performance air filter, can also improve airflow. You may also want to look at performance variator upgrades. The variator is a component that handles the automatic transmission function in the Ruckus. Consider all these potential additional modifications as you budget for your build.
Budget
Budgeting is a crucial element of the project. Consider the cost of the big bore kit itself, which will vary based on brand, displacement, and included components. Don’t forget to factor in the costs of additional modifications such as a new carburetor or exhaust. Finally, if you choose to have the kit professionally installed, be sure to budget for labor costs. Doing your homework will help you avoid any surprises, and you’ll have a clearer sense of the overall investment required.
Legal Considerations
Finally, before starting any modifications, familiarize yourself with any local regulations concerning engine modifications. Some areas have restrictions on modifications, and you should always comply with all the rules and regulations of your jurisdiction.
Installing a Ruckus Big Bore Kit – General Overview
Preparation
Before diving in, gather all your necessary tools, materials, and know what you’re up against. Gather all the tools and components needed for the installation, including the big bore kit, any supporting modifications, and all the tools required to perform the work. Be organized, and have everything within easy reach.
Prepare your work area. It’s important to have a clean, well-lit workspace. Before you begin, drain the coolant (if applicable). Consult the Ruckus service manual or the kit instructions for precise draining procedures. Ensure the engine is cool to prevent any burns. You should also remove the body panels and any other components that will obstruct access to the engine. This may include the seat, floorboards, and side covers, depending on the specifics of your Ruckus.
Step-by-Step (Simplified)
Now, let’s delve into the major steps in a generalized installation. Removing the cylinder head and then pulling out the old piston are where you begin. Once that’s done, carefully install the new piston and rings into the new cylinder, ensuring that the rings are properly seated. Now, slowly install the new cylinder onto the engine case, making sure the piston aligns with the cylinder. You will need to torque all fasteners to the manufacturer’s specifications. Incorrect torque can result in leaks or damage to the engine. Double-check the torque after installation. Reassemble any other components, and it’s time to move on to the next stage.
Troubleshooting Tips
Once you’ve reassembled your Ruckus, it’s time to prime the fuel system and attempt the first start. After that you should watch out for any issues.
