I just looked in my Clymer manual and it covers 1990-1995 models, and the listing of model #'s starts at 3742 for the 1990 models. My guess would be to say it's an '89. Get the other manual that covers the older ones and the list is in the front. Maybe someone on here has it and can tell you for sure.
