LUBRICATION SYSTEM INSPECTION AND SERVICING
Explanation of lubrication system process:
After the lubrication oil crosses the fi lter screen, it is pumped by the oil pump. Some of the oil goes into the big
end of the connecting rod and splashes on the cylinder wall and the small end of the connecting rod. Another
amount of oil goes through some oil passages, such as the shaft neck of the camshaft, and splashes on the cam
rockershaft and cam chain.
