Honda Odyssey FL350 Two-Piece Water-Cooled Cylinder Head Kit
Ordering, Lead Time & Installation Notes:
- Made-to-Order Lead Time: These cylinder heads are custom CNC-machined to order and carry an estimated production lead time of 2 to 4 weeks or more from the time the order is placed.
- Cylinder Head Bolt Replacement Required: Installation requires replacing the factory cylinder head mounting studs/bolts with longer hardware to accommodate the two-piece water-cooled jacket design. While straightforward, it is more involved than a simple head swap. Watch this installation walk-through video to review the process before you begin.
- Vehicle Compatibility: Designed specifically for the 1985 Honda Odyssey FL350R 2-stroke engine.
Honda Odyssey FL350 Two-Piece Water-Cooled Cylinder Head Kit
Keeping the factory air-cooled Honda Odyssey FL350R engine running cool has challenged riders since 1985. Mounted directly behind the driver's seat inside a restrictive roll cage, the factory engine receives severely limited ambient airflow. Under demanding riding conditions—especially in heavy sand dunes, slow technical trails, or during long full-throttle runs—thermal buildup happens fast. Overheating causes spark knock, power-robbing heat soak, top-end distortion, and severe piston seizures.
The Two-Piece Water-Cooled Cylinder Head Kit is widely recognized as the single most effective cooling and reliability upgrade available for the FL350R. By converting the combustion chamber and cylinder head dome to liquid cooling, this kit dramatically slashes top-end operating temperatures, stabilizes combustion thermal cycles, and ensures your engine maintains peak horsepower from the beginning of your ride to the end.
Engineered with an innovative two-piece modular design, this cylinder head features a high-velocity internal water jacket engineered for optimal coolant circulation around the combustion bowl and spark plug base. It allows your 2-stroke powerhouse to work harder, run cooler, and survive
