Good To Know

Q: What happens if the flange leaks? A: An intake leak lets unmetered air into the engine, which can cause a lean condition, rough idle, and possible piston damage. Replace a cracked or hardened flange promptly.

Q: Does this flange match the stock carburetor? A: It is built to the OEM 420-8678-48 fitment for Mach Z 800 carburetor mounting. Confirm your model year and carb setup before ordering.
