gwest_ca-(File Mod) 10,441 #2 Posted January 25, 2019 If the long decals on the hood are mostly maroon it is 1988 or 1989 model Click on the pictures In 1990 and on the hood decals are mostly black This one covers 1991-1997 The serial number is the best way to identify the model year along with the model number. Both should be on a decal under the left side of the seat on the rear fender pan. Keep us posted on your progress. Lots of help here. Garry 1 Share this post Link to post Share on other sites
