· Engine/Transmission Oil Level Check

Start engine, allow to reach normal operating temp.

Stop engine and support bike in upright position for a few minutes to allow oil to settle.

Remove dipstick and clean.

Place dipstick back in but DONOT screw in.

Check level should be between the two marks.

· Brake Fluid Check

Support bike in upright position and check that the front brake reservoir window has brake fluid in it with a small bubble towards the top.

Check that the rear brake reservoir level is between the two marks.

· Coolant Level Check

Start engine, allow to reach normal operating temp.

Support bike in upright position

Remove radiator cap using a rag and check radiator coolant level
