Why are torque plates necessary for cylinder honing?

Torque plates are essential because they simulate the clamping force of the cylinder heads and gasket. Honing a cylinder without this simulated stress can lead to distortion, affecting ring seal and performance once the engine is assembled.

What specific engine types does this kit fit?

This kit is designed for 1999 and newer Big Twin motorcycle engines that utilize 4-1/8 inch cylinders. It's important to confirm your engine's specifications before purchase.

What is the benefit of using this kit for engine rebuilding?

Using this torque plate kit during honing ensures your cylinders remain true to their intended dimensions under load. This leads to improved ring seating, reduced oil consumption, and a more reliable, higher-performing engine.

About this part

Product Details

S&S Cycle has been a well-known name in performance engine parts for decades, and they're known for building components that help you get the most out of your motorcycle's engine. This 4-1/8 inch Torque Plate Kit is a prime example of their commitment to precision engine building. If you're working on a 1999 or newer Big Twin engine and want to ensure your cylinders are perfectly round and true after honing, this kit is what you need.

When you hone a cylinder without simulating the stress it will experience once the cylinder heads and gasket are installed, the cylinder can distort. This distortion can lead to issues like poor ring seal, oil consumption, and reduced performance. S&S Cycle's torque plates bolt onto the cylinder block, mimicking the clamping force of the cylinder heads and gasket. This allows you to hone the cylinder while it's under that simulated stress, ensuring it maintains its intended dimensions once the engine is fully assembled. This level of precision is crucial for building a reliable and high-performing engine, especially when you're pushing the limits with larger displacement or performance modifications.

This kit includes the necessary torque plates designed to fit your 1999+ Big Twin engine with 4-1/8 inch cylinders. By using these plates during the honing process, you're setting yourself up for a much better outcome, ensuring your new rings seat properly and your engine runs as smoothly and efficiently as possible. It's a critical step for anyone serious about engine rebuilding.
