Carb issue

Recommended Posts

I have a a California DRZ400s. Having carb issues looking for info on jets. Everything I read metions only a main jet and a pilot jet. Mine clearly has a third jet in the top of the float chamberand I cant find any info on what the jet is for and the size it should be. Trying to get it back to stock and hopefuly eliminate endless issues Im having with it. Anyone? Thanks

The third jet is the starter jet. It remains the same as stock for any mods you do. It is identical in appearance to the main jet. If you look carefully, on the sides of the jets, numbers are stamped. The larger numbered one is the main jet (center of the carb, sticking out far.)

I have heard it called a few things, like air jet, or starter jet, but them someone says, oh your carb doesn't have whatever.... whatever it is, it is a 62.5 mikuni jet
