3. Operation and Performance Benefits
Once properly installed, your 6 Sigma Jet Kit will significantly enhance your motorcycle's performance and engine longevity:
- Increased Performance: Designed to improve all RPM ranges of performance and throttle response. You can expect to feel a noticeable difference in power delivery.
- More Peak Horsepower: The kit is designed to gain 6%-8% in horsepower with intake/exhaust modifications, and 2-3% on a bone stock setup.
- Longer Engine Life: By correcting the air/fuel mixture, the engine runs cooler, which increases the lifespan of engine components and prevents damage from lean conditions.
- Reduced Exhaust Popping: The kit stops lean exhaust popping, a common indicator of a lean condition that can damage engines.
- Lower EGT's (Exhaust Gas Temperatures): Crucial for modified bikes, as running lean causes detonation and hotter temperatures, which can ruin exhaust valves and destroy engines.
The comprehensive nature of this jet kit ensures that all throttle positions are addressed, unlike simply replacing main jets which only affects full throttle.
