BX4 Basic BX4 Billet Builder kit 650cfm

Product Description

Part Number:49321BX4
Basic BX4 Billet Builder Kits are an excellent option for the professional carburetor builder to assemble and calibrate a carburetor to their respective needs without the excess work of scraping gaskets and reworking parts.
These are basic representations and can be customized to your needs. These kits are completely un-assembled and need to have boosters installed and all components assembled.
Jets and air bleed are not included but are available upon request from the builder.
Billet-made components in the USA are easy to assemble and accurate every time.
Custom applications are available. Please call your customer representative for details on customization.
Custom engraving is available for the metering blocks, and on the main section, applicable fees apply.
