On the chart I use The model is listed down the left side, the next column is the year built, the next is the series code, last is the frame/engine numbers. Start in the right side list of numbers, scroll down to find your number. It won't list your exact number but gives number that starts the range of numbers.
Number 447-100101 was the first number used for the build year listed in the second column.
The next year is 447-200101. Does your number fit between these two? If so then your build date is August 74 to July 75. This makes your bike an XS650 B This was the 75 model year.
