• Pull the exhaust side of the cam chain taut to install the camshaft sprocket (exhaust side).
• Turn the exhaust camshaft so that the timing mark C is aligned with the gasket surface of the cylinder
head. Engage the cam chain with the exhaust camshaft sprocket.
• The other timing marked D should now be pointing straight up. Starting from the roller pin that is directly
above the timing marked D, count out 13 roller pins (from the exhaust camshaft side going towards the
intake camshaft side).
• Engage the 13th roller pin on the cam chain with the timing marked E on the camshaft sprocket (intake
side). Refer to the following illustrations.
NOTE:
The cam chain should now be on all three sprockets. Be careful not to move the crankshaft until the cam-
shaft journal holder and cam chain tension adjuster are secured.
• Install the dowel pins 1 and C-rings 2.
• Install the camshafts, intake 3 and exhaust 4.
• Apply grease to the new O-ring 5 and install it to the cam-
