the main caps were a nice snug fit when i slid them into position, and the crank was quite tight to turn once the mains were torqued down. I did not use a new gasket for the pick up although it appeared ok i will replace with a new one. Been talking to my boss about it today and he reckons i should have packed oil pump with grease as the oil will run out due it been stood a few week since i built it up.
