I just realized that unless it different than the xs400 that the engine number is the same as the original frame number, so that should enable you to figure the year.

Motorcycle/ATV Year Model Identification

Identify your year model by using the letter of the alphabet used as the last digit in the units model name.

Eg. YZF-R6S S= Year Model Letter = 2004

YZF-R6T T= Year Model Letter = 2005

early yam's used these codes to identify the modal rather than the table shown.

This would mean RD50M (1978 code 2L8) would be 2000 (M)

RD200DX (1977 modal code 1E7) would be 2008 (X)

XS650S (1979 modal code 3L1) would be 2004 (S) or 1986 (S)

XS1100 (1978-80 modal code 2H7) would not exist

XJ900S (1998 modal code 4KM) would be 2004 (S) or 1986 (S)

FS1E (1973 modal type 394 ) would be 1978 (E)

RD250LC (1980 modal type 4L1) would be 1976 ©

then you run into points of say XS250SE (1980, 4G5) and XS7502D (1977,1T5)

how about the 1976 RD250 - 2 versions SP & CW (1A2)

so it's not much good for older kit the 3 digit code will identify the correct modal
