Hi Dean, Your bike needs about 4 pints of oil,be sure to squirt a 1/4 pint into the sump via the plug at front of the motor this primes the pump. Is this a rebuilt engine? the reason I ask is there´s a sludge trap in the bottom end needs to be clean before you turn it over or you may have big problems. For info see the (www.BritBike.com) forum lots of good stuff there. Good luck Bill.
