NOS Kit Installation
Nitrous oxide systems (NOS) can be installed to boost power during races temporarily. NOS works by injecting nitrous oxide into the engine, creating more oxygen and allowing the engine to burn more fuel. This upgrade should be used with caution and only by experienced users.
Other Performance Upgrades
Additional upgrades are available, such as porting and polishing the engine’s head, installing a performance carburetor, and upgrading the ignition system. Each upgrade should be carefully researched and considered before installation. You can find more information on performance upgrades here.
Notes
Inconsistencies Between Manufacturers
Modification stages may vary between manufacturers, which can create confusion when comparing different upgrade kits. Therefore, focusing on the power increase and specific components in each stage is crucial rather than just the stage number.
Power Increase Perspective
Understanding the power increase perspective is essential when modifying the Predator 212cc engine. It allows you to prioritize the components that will deliver the desired performance improvements while ensuring compatibility with your engine.
Speed Governor Removal
Before starting the modification process, remove the speed governor from your Predator 212cc engine. The speed governor restricts the engine’s speed, limiting its potential for high-performance go-karting. By removing the speed governor, you’ll unlock the full potential of your engine and ensure optimal performance after modification.
