For sale is an Allgeyer Performance Products carburetor adapter.  The Use this adapter to retrofit a Keihin FCR onto your TRX450.  The new adapter from Allgeyer Performance Products builds on the popular APP-1001-2 design for DRZ400s and allows a Keihin FCR carburetor without the removable intake bell to be installed onto your Honda.

FCR’s without the removable intake are common on 4 stroke racing four-wheelers and dirt bikes. FCRs without the removable intake bell are identical internally to those with the removable intake bell, but can be obtained much cheaper. The adapter allows an FCR without the removable intake to be installed onto a TRX450 with significant increases in horsepower throughout the RPM range.   

Products have been specially engineered with the following features. 

• Velocity stack to minimize turbulence of incoming air.

• Optional side holes for secure mounting using set screws and locating slot to prevent movement.

• Adapters can be used with FCR's of various bore sizes (for example 38, 39, 40, 41mm etc.).

• The engineered plastic has been specifically selected for its properties as a heat barrier.

• All adapters have been tested to withstand normal operating temperatures and for gasoline resistance.

• No modifications are required to your carburetor to use this adapter.

Parts are made in the USA and kits have been installed on hundreds of motorcycles!
