Well done. It does make you feel good when things turn out right. It is certainly better to have a short bedding-in period after a rebuild. Not 'running-in' as that is mainly for the benefit of the cylinder & piston, which have not been changed. Bearings should not need any running-in, nor seals, so it is more a case of checking everything works as it should at varying loads before going flat out. Suggest you run it up and down the gearbox, at reasonably high revs, for a while. Check all your engine mount bolts for tightness, together with the cylinder head and exhaust nuts when the engine is good and hot.

1956 D3 running, lights to sort. 7 other bikes in the Barn. 1950 D1 engine being rebuilt (slowly).
