Franx Posted October 12, 2009 Share Posted October 12, 2009 The number on the frame and engine is 2J5-007853. We were told it's a 1979 YZ80"E" when it was bought in 1988. Anyone have info on the numbers for these little bikes?? Thanks. Link to comment Share on other sites More sharing options...

Franx Posted October 13, 2009 Author Share Posted October 13, 2009 Thanks for the reply. I researched "YZ serial numbers" and it would appear that my bike is a 78 YZ80E (2J5) and not a 79 (2X6). Link to comment Share on other sites More sharing options...
