Whatever you do, if you're going belt drive to run the primary dry i.e. no oil leaks, make sure that it is designed to run dry e.g. the clutch centre bearing is a sealed type and not the old BSA/Triumph 20 roller type which will soon destroy itself without lub. I've just given up on one and bought a Bob Newby.
