After a recent visit to the National Motorcycle Museum at Nabiac, NSW, I came home with the idea of building a replica of Brian Collins record setting bike that he built in 1973 and set three Australian Land Speed records with at Lake Lefroy in WA. Now I just happen to have a spare Yamaha YB100 engine and bits left over from my 1974 YB100 restore, and the more I thought about it I thought 'why not make a copy'. I will never take it to the salt lakes, but will probably give it a run on some quiet country roads. I knew the engine had been through a flood, but when I got it about two years ago I drained the engine and filled with Diesel. It was, I since found, too late and the damage had been done. I brought it home and put on the bench. The mice had had a lovely time in the aircleaner. I lifted the engine out and off with the head. Tried the hot oil, but no good. Too far gone for anything but a big hammer. Took the side cases off and it didn't look much better.
