Without getting into too much detail start by removing the valve covers, heads and cylinders. Remove the left side engine case which will reveal the stator, flywheel, timing chains, oil pump, etc. Removal of the flywheel will require a special tool (refer to service manual for tool part numbers). Remove the starter, water pump housing and water pump. Remove clutch cover and clutches (special tools required here also). Remove the air deflection shield found behind the front or primary clutch. This shield serves as a retainer for the front cylinder timing chain installation plug....remove this plug. Now remove all timing chains. Remove all crankcase bolts from both sides of the engine. Lay the engine on it's clutch side and remove the left crankcase half.
