Restore proper fuel delivery and carburetor performance with this Premium Carburetor Rebuild Kit, designed for Honda twin-cylinder carburetors. This kit features long-lasting, high-quality Viton components, known for their durability and resistance to fuel and heat, making it ideal for long-term reliability.

Over time, carburetor gaskets, seals, and internal parts can wear out or degrade, leading to fuel leaks, poor idle, or inconsistent throttle response. Rebuilding your carburetor with fresh components helps restore proper fuel metering and smooth engine operation.

Frequently Asked Questions

How many premium carburetor kits are needed to rebuild all carburetors on a 1978-1981 Honda CB400?

One kit rebuilds one carburetor. The 1978-1981 Honda CB400 uses 2 carburetors, so 2 kits are needed for the complete carburetor bank.

Which calibrated carburetor parts must be matched before installation?

The kit includes #72, #78, #105 and #110 main jets, a #42 pilot jet and the supplied slow-jet parts. Compare every jet number, needle code and float-valve size with the original carburetor and the Honda specifications for the exact model before choosing among any supplied alternatives.

Does a rebuild kit correct every carburetor problem?

No. Clean the carburetor passages ultrasonically or with approved cleaner, check the float and throttle shaft, set float height, inspect intake boots for leaks and synchronize multiple carburetors after installation. Replacing parts cannot compensate for blocked passages or worn castings.
