It includes a durable, high-temperature exhaust valve seat material, which helps to prevent exhaust valve seat recession and extends the life of the cylinder head. The head also includes a high-quality, O-ring-sealed intake and exhaust ports, which help to ensure a tight seal and prevent leaks.
The Yamaha BJR 4861 cylinder head is a high-performance, durable component that is essential for the proper functioning of the Warrior 350 engine. It is designed to provide excellent power output, efficient fuel burning, and reliable operation, making it an ideal choice for boaters and other marine enthusiasts who demand the best from their engines. Whether you are looking to restore an older Warrior 350 or are in need of a replacement cylinder head, the BJR 4861 is an excellent choice that is sure to meet your needs and exceed your expectations.
