Funny you should ask. I keep an eye on the K0 parts occasionally. Here are some eBay offerings from last year...
08/17/05 Right Side Cover, Candy Gold with Badge NOS $500.00
08/17/05 Left Side Cover, Candy Gold with Badge NOS $500.00
02/21/05 Left side cover, 1969 CB750, Blue Listed as not perfect, no badge $249.00
Those were winning bid amounts.
