Keihin FCR MX mid-body gasket rebuild/repair kit #1.
These gaskets are not officially available through Keihin, since they do not want you to open the carb that way... You will receive 2 large gaskets and 2 small square ones (for the vent tube risers). Both large gaskets differ in detail (look closely), you will only need 1.
Attention: make sure these are the gaskets you need. These gasket will NOT fit FCR MX carburetors with removable intake adapter (that's the adapter which is attached to the carb with 2 screws).
Complete as pictured.
