Hi, I have a 94 kx125 I just rebuilt the top end on. I later found the governor spring gear that opens the power valve. Well the bearing are worn. When i ordered a new one it did not match the one in it. The one in it resembles a 93 governor spring gear. Could it have been built early enough they would have put the 93 spring gear in it? Just want to make sure before I order it again. Thanks in advance.
