Cylinder Works is known for making well-built engine components that offer a performance edge. This Big Bore Cylinder Kit is a prime example, designed to give your 2014-2015 Yamaha YFM 700 D Grizzly 4x4 a significant boost in power and displacement. If you're looking to get more out of your ATV's engine, this kit is a solid option.

This kit takes your stock 700cc engine and increases its displacement to 727cc with a +3mm bore, using a 105mm piston. It's designed to look like an OEM cylinder but perform like a race-ready part. The kit includes a hand-matched Vertex piston and a complete top-end gasket set with O-rings. This all-in-one approach saves you the hassle and cost of sourcing individual OEM parts.

The cylinder itself is constructed from a high-quality 2618 aluminum alloy, chosen for its strength and durability, which is crucial for handling the increased demands of a bigger bore. This construction helps ensure reliable performance and longevity. By increasing the engine's displacement and compression ratio to 10.1:1, you can expect a notable increase in horsepower and overall engine performance.

When you're ready to install, remember that this is a major engine modification. It's always a good idea to consult the manufacturer's installation instructions for specific details and any additional components you might need to complete the job safely and effectively. This kit is a significant upgrade for riders looking for more power from their Grizzly.
