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 6):
The internal combustion engine of a saddle riding vehicle according to  claim 5 ,\n wherein an oil filter is provided in the crankcase to filter oil to be supplied from the oil pump to the intake camshaft, the exhaust camshaft and the tensioner lifter.
