I'm the Wiz, and nobody beats me!
You think the frame is that old GT? I'd say 2008.
Pacific Schwinn built these HD for years using that frame and just changed the color scheme from year to year and possibly a few components. The earlier ones were all yellow and the one in that funky video is or was said to be a 2000. I'm going with a 98 model using the color scheme, serial number and headbadge stamping.
Here's the specs for the 1998 model.
