1980 - 1984 have a 9 digit serial number for the engine/frame. They will match, unless someone has changed the engine. VIN decoders will not work.
1985~ - 9 digit on engine, 15 digit on frame. You can use a VIN decoder to figure out the year.
I included the 1985~ numbers, in case you want to check and see if you have the correct year engine, in your machine (works on most models).
