What does a 6 Sigma Jet Kit do? ​

    Carburetors are typically designed to run with factory parts under standard conditions. However, when you modify your bike's exhaust or intake, it will lean out the fuel mixture, leading to excess heat and potential engine damage from detonation. If you notice exhaust popping, it’s a clear sign that your bike is running extremely lean.

   6Sigma Jet Kits provide all the necessary components and step-by-step instructions to enrich the fuel mixture across all carb circuits. This not only solves the issue of running lean but also protects your engine and improves performance, giving you noticeable power gains.

   6Sigma Jet Kit uses an engineering approach rooted in data and statistical analysis to enhance your bike's overall performance.

Take your ride to the next level with a 6Sigma Jet Kit—the single most effective and cost-efficient performance upgrade you can make.




​Why a 6 Sigma Jet Kit:

• Maximize Performance: Our kit is designed to unlock the full potential of your bike, improving performance, fuel efficiency, and extending engine life.         
• Custom Engineered: Each jet kit is tailored specifically to your bike’s year, model, altitude, and modifications, ensuring the perfect fit and optimal results.

Benefits

• More Peak Horse Power

          Designed to gain about 8%-10% in HP with intake and exhaust, 2-3% on bone stock.

• Longer Engine Life

           The jet kit is a performance upgrade that not only increases power, but allows the engine to run cooler which increases engine component life.

• Increased Performance & Efficiency

            Designed to improve all RPM ranges of performance and throttle response.

• Lower EGT's (exhaust gas temperatures)

            If you have installed an aftermarket, or modified the stock exhaust or intake, this is needed or you will damage your engine. Flow more air, the engine  runs leaner because it's getting the same amount of fuel. Running lean causes detonation and hotter EGT's which ruin exhaust valves and destroy engines. 

100% Performance Guarantee- This is the single most important, cost effective modification that can be made to your ride. If you don't feel the difference in the seat, and it does not put a smile on your face after installing, just return it for a refund!
With PayPal, you’re protected from checkout to delivery, and back.

"Hey mate I got the jets in my bike and it's fully sorted, a $40 kit
