FREEZING WEATHER CAUSES PAIN!
When water freezes and becomes ice, it
expands. Like most laws of nature a great deal of force
is available to burst pipes, crack engine blocks and even
break kart cylinders, radiators, etc.
How to avoid damage:
- Drain the water at the end of the day. Tip: put
radiator cap in tool box so as not to forget to fill
it at your next outing!
- Follow the instructions in the ROTAX handbook (that
orange document that comes with the engine but few
ever read) and add anti freeze to your water. Tip:
this is forbidden in CIK events so rather use water
until a letter from ROTAX clarifying that this does
not apply to South Africa is published. Unfortunately
one of the many karting legal experts might try to
protest you in the interim.
Can one repair a cracked cylinder?
Yes, if the crack is welded (by and expert!) one can
normally diamond hone the cylinder to correct distortion
caused by weld and use it successfully. Repairs of this
nature are allowed in the regulations for ROTAX classes.
