Hey guys I am new to the forum so first of all hi. I have a KX 125 and I'm not sure what year it is. I thought it was a 91 but i just bought some fork seals for a 91 and they dont fit, the guy doing it said I needed 41mm seals. someone told me that in the vin number you count back 8 digits and that letter tells the year. Mine says L so what do I have?
