Crankcase Blow-by Drain
The air cleaner has a drain tube ① that is for
draining the oil condensed fluid from the crankcase.
When the fluid has accumulated to a certain amount
in the transparent drain tube, remove the clip ② and
plug ③, drain the fluid into a container, and then
reinstall in place.
▆NOTE: Drain frequently if often riding in the rain, often at
full throttle, or the vehicle has been overturned. Follow the oil
disposal regulation.
