just ride it gently using a little throttle, engine braking and all the gears. The owners manual ought to be a good guide. One of the reasons for misconceptions now is often the choice of materials has changed over the years. However some basics are still true. One is that fresh cut/machined surfaces are soft and inclined to clag (seize) running them lightly work hardens the surface. This is really crucial with cast iron or cast steel bores. You need to build up to full bore full revs slowly as they start tight and soft. This is why you have to glaze bust old steel bores as they get so hard and slippery they do not provide enough grip to bed in piston rings. With chrome plated or nikasil bores ( like the new Enfields mentioned above) the material is much harder and smoother so the bores need little running in. They do however need to hone them to give a little roughness for the rings to grip so they can bed down. (also to hold a little oil as unlike cast iron they are not porous) Although there is much less to do running in nikasil bores because they are smoother and harder it takes longer to do it. Hence the problem of old advice/experience with older riders on new Enfields. Typically it now takes +3k miles to free up a new Enfield ( BMW quote up to 10KM before proper ring seating).
One thing I would advise is to change the oil/filter at about 50 to 80 miles ( use running in oil) as most of teh metal and other detritis that will ever come out of your engine until it fails will be in that time. It might seem like a waste, but I believe it to be cost effective.
