Carburetor Rebuild Kit - Honda S90 CS90 CL90 SL90

Carburetor rebuild kit for Keihin carburetors used on the Honda S90, CS90, CL90, SL90. It does not fit Mikuni carburetors. This is the most complete kit available! The float bowl gasket is made of Viton rubber which is the best quality available for carburetor parts. Viton rubber will not swell after coming in contact with fuel.

Some main jets in this kit are JIS thread pitch and some are ISO pitch which have a machined groove around the head.

JIS pitch was used mostly on pre-1967 Honda's with Keihin carburetors, in 1967 Honda switched to ISO pitch. Some models continued to use JIS pitch through the production run even past 1967. JIS pitch jets do not have a machined groove around the head. (smooth) The difference can be seen in the photo. Both ISO and JIS versions of the 85 main jet are included since Honda changed thread pitches but used the same size jet.

NOTE: Only fits Keihin carburetors. There were many types of carburetors used on the SL90 this kit does not have all parts needed check photo before ordering.
