For sale is an Allgeyer Performance Products carburetor adapter.

This adapter works with generation 1 Keihin MX BSR carburetors with diameter 38, 39, 41mm.  These carburetors are identified by the bolt on adapter, located where the carburetor couples to the airbox. 

Using this adapter, you can connect the BSR carburetor to the following:

·       Honda 400EX with stock airbox

·       Honda 650R

·       Honda TRX450R with pod filter (only 2004/2005 models)

*If using an aftermarket pod filter, be sure it will clamp to the adapter.  The outer diameter of this adapter is 2.47”.

This model is ½” longer than the APP-2002-2 but is the same dimeter on the airbox side.

Products have been specially engineered with the following features. 

·        Velocity stack to minimize turbulence of incoming air. 

·        Adapters can be used with FCR's of various bore sizes.

·        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 over 1000 motorcycles!
