http://cgi.ebay.ca/Kawasaki-Ninja-6...rcycles_Parts_Accessories&hash=item2c5766321cI don't have a rad. but I did do a ghetto tar/chip preventative measure on the rad. I bought a diamond honeycomb sheet, cut it with snips to the rad's size... then used good quality "zip strips" and weaved it through the honecomb attaching the breathable sheet over the back of the radiator mounting brackets. pretty helpful mod.... not sexy but it works.
good luck with your radiator search
I have a couple, but I've cut the fan mounts off.
