Please Note: The jet sizes included in this kit are dependent on your year/make/model.  Because bikes are always typically modified and/or re-jetted you will need to verify what jet sizes are in your current carburetor so we can include those specific sizes with this kit.  

All of the above parts can be ordered individually and kits can also be customized depending upon your particular needs.  

 We can also recondition your OEM FCR carburetor to like new conditions using these rebuild kits.  Custom calibrations for specific applications are also available, please inquire for more information.
