Product Description

Replica Keihin Japanese Industrial Standard (JIS) thread pitch round main jet. We have a range available from #100 - #145. 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 so open your carburetor and check to be sure! It's fast on some models to remove the float bowl and see if there's a machined groove or not.

These are NOT International Standards Organization (ISO) pitch jets, so they do not have a machined groove around the outer diameter. That groove was used to differentiate the ISO jets from the JIS jets which have a smooth edge. (no groove)

Aftermarket exhaust? High flow air filters? Looking for more power? You're gonna need to up-jet. Fuel today is different from the 1960's so it's common to re-jet for modern fuel. Or maybe you're just cleaning the carbs and need some new stock size jets? Pick your size from the drop down menu above. Make sure to lightly seat the jet, do not over tighten them.

NOTE: Check the jet in your carburetor to be sure you have a JIS pitch jet which does not have a groove on the outside edge. (see product photo) We also carry the ISO pitch round main jet.
