I bought these for a KZ400 carb rebuild project but i didn't measure my carbs correctly and ordered the wrong ones. They were brand new from JBM industries and are OEM or better quality. they are for the Kehin cv-32 cv-34 carbs. they should fit KZ250, KZ440, KZ400, KZ750/4 carbs. $30 for the pair shipped in the continental US.
