The fork gaiters are original, that pic is 1987.
I understand that the 1982 'LS had white wheels and no gaiters, subsequent years had silver wheels and those fine ribbed gaiters. There are about 15 ribs (the photo is grainy).
Current parts list on both Motobins and Motohansa is a thicker, 11 ribbed version. I have them on my current 'LS, but they don't look "right" (but they're better than dusty stanchions).
