From this: http://www.ozebook.com/compendium/suzi/engine-nos/page1.gif
1972 is first year so frame & motor start at GT380-10001
1973 frame starts at GT380-10919 & motor starts at GT380-32894

But that 1973 frame # has to be a typo.
Per this http://www.suzukicycles.org/photos/identification/FRAMELIST_1200-pix-wide.jpg
1973 frame starts at GT3890-30919

They made more crankcases than frames and didn't try to keep matching numbers. But early first-years bikes might have matching numbers.

Thanks. I will find that useful too. Will check if my engine is original, just out of curiosity.
