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:

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

Products have been specially engineered with the following features.

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