FUEL INJECTORS
There are two type of fuel rails made by Radium: upgrade rails and top feed conversion rails. Upgrade rails only upgrade the rail and the OEM fuel injectors can be reused. If an upgrade to the injectors is desired, they must be equivalent to the OEM injector, meaning they must be the same height and the upper & lower O-rings must match the OEM diameters and styles. Top feed conversion rails are used to convert a vehicle that has side feed (or sometimes air-assist) injectors over to a top feed injector.
This fuel rail is an upgrade rail. OEM or OEM equivalent injectors must be used.
Radium does not make fuel injector recommendations.
- Consult your tuner for injector brand or flow rate recommendations.
- Consult the injector manufacturer for a part number that has the correct dimensions.
OVERVIEW
20-1136 Fuel Rail, Kawasaki Ninja/Teryx H2 Primary
This large 8AN fuel rail is manufactured to support all necessary engine power requirements. The rail is CNC machined from solid 6061 aluminum, anodized and laser etched for a high quality surface finish. It is compatible with all fuel types including popular alcohol mixtures such as E85.
The fuel rail ports are tapped for 8AN ORB fittings.
- 8AN ORB Adapter Fittings can be found HERE
- 8AN ORB Direct Mount Regulators can be found HERE
- 8AN ORB Fuel Pulse Dampers can be found HERE
- Fuel Pressure Gauge Adapters can be found HERE
Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.
20-1136-PK Fuel Rail Plumbing Kit, Kawasaki Ninja/Teryx H2 Primary
The plumbing kit includes the items in the image. It includes a dual banjo fuel feed adapter fitting that makes the kit plug and play for the hypersport H2 bike and the track-only race H2R bike.
NOTE: The primary fuel rail lines on the Kawasaki Z H2 "hyper-naked" street bike are different. Both OEM fuel lines are on the same side of the engine instead of opposing sides like the hypersport H2 bike and the track-only race H2R bike. If installing this fuel rail on a Kawasaki Z H2, it is recommended to purchase the 20-1136-PK along with the fittings pictured. This will permit the second fuel line to be attached with no other modifications.
