What is the main advantage of a gear drive camshaft over a chain drive?

Gear drive camshafts offer a more direct connection between the crankshaft and camshaft, eliminating the potential for chain stretch. This results in more precise valve timing and a more consistent power delivery over the life of the component.

What kind of performance improvements can I expect with the 625GE profile?

The 625GE profile is designed to enhance mid-range torque and horsepower. This means you'll likely feel a noticeable improvement in acceleration and pulling power during everyday riding conditions.

Are there any special considerations for installing this camshaft?

Yes, it's important to follow the S&S Cycle installation instructions carefully. Gear drive systems require precise alignment and proper setup to ensure optimal performance and engine longevity. Always refer to the manufacturer's guide for detailed procedures.

Product Details

This S&S Cycle 2006 Big Twin Dyna Easy Start 625GE Gear Drive Camshaft is designed to give your Harley-Davidson Dyna a noticeable boost in performance. If you're looking to improve your motorcycle's power delivery and starting ease, this gear-driven camshaft is a solid choice for your engine build. It's engineered to work with the specific requirements of the 2006 Big Twin Dyna models, ensuring a direct integration into your existing engine setup.

The gear drive design is a key feature here. Unlike chain-driven cams, gear drives offer a more direct connection between the crankshaft and camshaft. This means less timing chain stretch and slop over time, leading to more precise valve timing and a more consistent powerband. The 625GE profile is specifically chosen to provide improved torque and horsepower, especially in the mid-range where you'll feel it most during everyday riding. This updated camshaft profile aims to make starting your Big Twin easier while also enhancing overall engine performance.

When installing a gear drive camshaft like this one, it's important to follow the manufacturer's instructions closely. Proper installation ensures you get the full benefit of the improved timing and performance. While this camshaft offers significant performance gains, please note that it is not CARB approved and cannot be shipped to California. Always consult the S&S Cycle installation guide for detailed procedures and any additional components you might need for a complete and successful engine upgrade.
