Hey guys, I have a question about the vin on my 93 KX125. I purchased the bike about 6 mos ago, got a signed bill of sale, but did not check the vin upon purchase. After getting it home, cleaning it up (it was a cruddy basket case) and looking for the vin on the headstock, I found that the 13th and 14th digits have been ground off (appears to be intentional). The partial vin that I have is JKAKXRJ11PAC (or O?) _ _ 972. I know that the last 5 digits are for production numbers, so would anybody have any idea how to find out those two digits? Can I use the engine # to cross reference it in any way? That # is still intact. I have heard about using acid to reveal the impression in the metal, but what kind of acid? The grind marks are pretty deep, so I dont know. Any help would be appreciated.
