3.8 Press-fit float valve seat for Keihin FCR MX carburetors.

This seat is not available from Keihin; it replaces the press-fitted factory OEM seat. Made out of brass, precision machined to the highest specifications.

This fits: all 37-41mm. Keihin FCR MX flatslide carburetors (which came with a press-fitted seat).

Attention: installation needs to be done by a person with some mechanical skills. An installation guide will soon be available.
