Testing your motorbike for antifreeze
Make sure you test your vehicle for antifreeze as if your engine freezes it will split the barrel and head and cause a lot of damage.
Use this tester, remove cap to radiator water and fill it by pressing bulb at top to suck water in. the more balls that float the better protection you have. In the UK you need minimum of 2 balls floating.
See video of this below.
