Oil circuit bolts are screws or screw caps used in a motorbike's oil system to control oil flow or provide access to certain components. They are used for maintenance, oil replacement and to ensure safe and efficient oil circulation.
Typical bolts include the oil drain plug, which is used to drain used engine oil, and the filler plug, which is used to add fresh oil to the oil tank. In addition, there may be bolts on oil filters, oil pumps or other parts of the oil system.
It is important that the bolts are properly tightened to ensure secure sealing and prevention of leaks. When replacing oil or servicing the oil system, it is advisable to tighten the bolts carefully, according to the manufacturer's specifications or torque specifications, to prevent damage or leaks.
