I have just been back to California and picked up the Project bike that I got through Raber's in March this year. I managed to strip the bike apart to assess what I have to work with and was pleased to find that it is still on standard crank grind and cylinder bores. It does need a complete restoration and there are quite a few parts missing, but it is a matching numbers bike and I already have a tank and battery/tool box which can be hard to source. I am looking forward to picking the brains of the N15/G15 owners and experts on this forum as I get further into the project. I have the chance of buying some parts of an old 650 SS here in HK. The frame and other bits and pieces like the tank, seat instruments etc are long gone so perhaps I may be able to put what's left to good use in resurrecting this project.
