Remove the plug bolt from the back of the cam chain tensioner assembly. It is under pressure from the spring. Remove the spring and pin. Remove the bolts and tensioner assembly from the cylinder. Release the lock on the tensioner assembly and push the tensioner rod into the assembly so that it is fully retracted. Remove the eight 5mm Allen headed bolts that hold the cam caps in place. Remove the cam caps; be aware of the locating dowels in the caps to keep them from falling into the engine. It may be necessary to pry very lightly on the caps to lift them off their dowel pins. Do not use the cam lobe as the pry point. Lift the intake camshaft out of its pocket in the cylinder head casting. Remove the cam chain from the sprocket, set the stock camshaft aside. Lift the exhaust cam out of its pocket in the cylinder head casting and remove the chain from the sprocket. Do not drop the cam chain; dangle it over the side of the engine while keeping slight upward pressure on the chain to maintain its position on the drive sprocket on the crankshaft. Using assembly lube, lube the shim buckets and bearing surfaces for the camshafts in the cylinder head. Set the exhaust camshaft into the cylinder head casting while at the same time fitting the cam chain over the sprocket. Make sure that you keep all the cam chain slack to the back of the engine. Repeat the above process for the intake camshaft. Again, make sure you keep the chain slack to the cam chain tensioner side of the engine. Check to be sure the crankshaft is still at TDC. Check the location of the cam lobes. The camshafts are marked, and preset to 108-degree centers. If the lobes are not where they should be, adjust the positioning of the camshaft by rotating the sprocket one tooth on the chain. Do this until it is in the correct position as before you removed the camshafts. Check the positioning of the crankshaft for the TDC mark
