I read about this sometime ago in a US magazine. The crankshafts are coupled on the primary side by chain with an additional chain to the clutch, interestingly a scissor clutch. For some reason it is also coupled on the timing side by gears. As i recall the gears sit outboard of the timing covers and the engine using the standard timing with 2 mags and standard oil pump setup. Not sure what benefit this had, maybe they kept breaking the primary chains. Strange as most other twin engined record bikes seem to manage with just a chain. Richard
