Abstract:
A cam chain tensioner device of an internal combustion engine includes a cam chain tensioner, and a tensioner lifter pressing the cam chain tensioner to a cam chain. The tensioner lifter is mounted on an inclined upper surface of the cylinder head. The cylinder head has therein a valve train oil supply passage supplying oil from an oil pump to the valve train camshafts, and a tensioner lifter oil supply passage supplying oil to the tensioner lifter. The valve gear oil supply passage has a branching portion where the tensioner lifter oil supply passage branches. The branching portion is at a position higher than the tensioner lifter, and communicates with the tensioner lifter disposed at a position lower than the branching portion. It is thus possible to prevent fluttering of the cam chain and to reduce noise generated by the cam chain at the time of restart of the engine after it is stopped.

Claim (Index 5):
The internal combustion engine of a saddle riding vehicle according to  claim 4 , wherein:\n the camshafts include an intake camshaft having an intake cam and an exhaust camshaft having an exhaust intake cam, the intake camshaft and the exhaust camshaft being arranged parallel to each other with a center of the cylinder portion located there between, as viewed in the direction of the cylinder axis; and the center oil passage branches into oil passages toward the intake camshaft and the exhaust cam shaft to supply oil thereto.
