I know this thread is old, but am going through this key exercise, tried the ILCO X109 FT43 route and no go, am going to try the ILCO Y61 trial tomorrow. Am doing a complete spring checkup and thought I'd better get some spare keys, the PO only had one set, one key (Neiman GKS) for the ignition and rear side luggage, a different key (folding BMW) for the fuel filler and front storage compartments. As I have the bike in a very advanced state of disassembly I can't take it to the locksmith so I guess it's trial and error time. Luckily, it's not a Land Rover...
