I wonder what kind of oil this guy was running. It would be fun to run Castrol castor bean oil like they did in the old days, and a lot still do, but there must be something better out there by now. I called the Barber museum one day and talked to their mechanic and he said they run Mobil synthetic motorcycle oil in their bikes. Not too long ago most of the additives to prevent wear on flat-tappet engines was taken out of most off-the-shelf motor oils as most autos now have roller-tappets. There is the Rotella oil for diesel engines that is supposed to have all the old additives in it still. With the cost of Manx parts, whatever oil is in the engine better be damn good stuff! Then there is viscosity, originally they specified a lot of straight grade oil for bikes with rolling-element bearings, but many now are running multi-vis in them. Whatever viscosity, having the oil good and warm before using a lot of throttle and revs has to be a good idea.......
