Technically, nothing. But I did pick up the spin on oil filter conversion kit that had been on my Goldwing from the guy who bought it. I had made him a deal to get it back as he wanted to go back to the original cartridge filter setup. I plan to use it on my 550.
I also go to see his bikes, 2 immaculate GL1000's, a '75 standard and a '76 LTD, and a never titled CBX, a '79 I think.
