Liam advise sounds good to me. Re-built engines should have had a hone applied to the cylinder. The only real purpose to running in is to allow that hone and the piston ring time to settle. The hone is a cross hatch glaze pattern which assists with oil retention but if excess heat is allowed to build up it can act to create a glaze on the piston ring, which will affect ring seal. I dont know that I personally would allow the engine to rise to max rpm during the running in period but I do recommend the application of short burts of full throttle on corner exit, the reason being that the combustion process forces the ring outwards against the cylinder wall and smooths off any high spots in the hone marks. HTH.
A high oil to fuel ratio is always a winner but just be aware that it can alter jetting requirements slightly.
