3. Setup and Installation
The 6 Sigma SP450 Nitrous Oxide Kit is designed for easy installation using basic hand tools. Follow these steps carefully to ensure correct and safe setup.
3.1 Nitrous System Installation
- Mount the NOS GO Button Dispenser: Choose a convenient and secure location on your ATV's handlebars or frame. Use the provided UV resistant zip ties or a suitable bracket to firmly attach the dispenser.
