Get ready to pony up some cash, that is if you can find em. A quick ebay search for "buell blue translucent" yielded the following:
Windscreen: https://www.ebay.com/itm/26513504499...4AAOSwY3VeeJQT
Front Wheel (1125r): https://www.ebay.com/itm/14403535383...8AAOSwrCdgmV0v
Not sure if there's conversion needed for 1125 front wheel to xb. Your search will take time and will be piecemeal. I've been keeping an eye out for a new or used with no cracks cherry bomb airbox cover for years, and I've pretty much given up.
