Frequently Asked Questions
How many premium carburetor kits are needed to rebuild all carburetors on a 1973-1975 Honda CB125S?
One kit rebuilds one carburetor. The 1973-1975 Honda CB125S uses one carburetor, so one kit completes the carburetor.
Which calibrated carburetor parts must be matched before installation?
The kit includes #105 main jet, #38 pilot jet and D29M jet needle. 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.
