Water Cooled Head With Radiator Kit

$799.95

In addition to what is included with the head, the radiator kit also includes the radiator, hoses, clamps, brackets and cap. The all aluminum radiator is custom made for use on the FL350 Odyssey. An oversize upper tank prevents the need for a separate recovery tank. The angled mounting causes airflow by convection preventing the need for a fan. The brackets are powder coated red for a durable finish. The bracket mounting tabs are laser cut. The aluminum radiator is separated from the steel brackets by rubber insulators and stainless steel crush sleeves.










The Aftershock Motorsports water cooled head for a Honda FL350R Odyssey includes the fittings, longer studs, acorn nuts, washers and O-rings. This is the CNC machined scalloped design head.

The replacable dome allows having multiple combustion chamber sizes that can be changed to raise compression for high altitude or racing. It allow allows replacement of just a portion of the head in the case of damage from an engine failure.

The FL350R ran hot from the factory. The original head was replaced in a recall to reduce the operating temperature. Other changes were also made such as lowered compression which reduced power output. Even with these changes, these machines still run hot. If you live in a hot climate, you may not be able to ride continuously for long periods of time without having heat related problems. Modifying the motor for more power can push the heat levels beyond what the piston can handle resulting in seizures or stuck rings.

The head is machined from solid aluminum into two main pieces. The inner dome section fits inside the outer shell sealed at the top and bottom by O-rings. A 90 degree fitting on the front of the head connects to the lower connector on the radiator. A straight fitting on top connects to the top of the radiator. The two piece design allowed adding fins around the combustion chamber to improve heat transfer.
