6-30 CYLINDER HEAD, CYLINDER AND PISTON
• 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 13 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 holders and cam chain tension adjuster are secured.
• Install the dowel pins and C-ring
1.
• Install the camshaft journal holders, intake and exhaust.
NOTE:
* Camshaft journal holders marked “EX” are for the exhaust side
and those marked “IN” are for the intake side.
* When tightening the camshaft journal holder bolts, the piston
position must be at TDC on the compression stroke.
• Tighten the camshaft journal holder bolts to the specified
torque.
NOTE:
Tighten the camshaft journal bolts diagonally.
