■ New system
By installing the separately sold oil line hose kit, the oil flowing to the cylinder head side can be passed through the oil element.
This prevents engine damage caused by oil sludge, etc.
To install the separately sold oil line hose kit, it is necessary to install the bore-up cylinder with oil outlet made by TAKEGAWA at the same time.
