So, to start off, I'm real new with the moped thing, got my first one a week ago, it's in terrible shape, im trying to find out what year it is so I can get the right parts to start wrenching but unfortunately the dick I bought it from removed the VIN stickers. The only number I can find is the engine serial number; is there some way I can use that to figure out the year this thing was made? (All I know is it's a tomos targa, halp.)
