Thanks for the replies. I do plan on taking it to a shop for a tune up. It has really been sitting around for 20 years, but I did loan it to someone last year for a few months who took it to a shop to get it working again.

Can most bikes be made to fit most people? What do they do? Do they do things like raise/lower the handlebars? Of course they would raise/lower the seat. Any thoughts on a good new seat to get?
