6.4.  Shut Down 

1. 

Take a slightly slower out-lap. 

2. 

Switch the engine off as soon as you have reached the paddock. 

3. 

Let the engine cool down. 

4. 

To make sure the onboard-starter does not start the engine unintentionally, you should 
disconnect the positive (+) terminal from the battery when you park your kart. 

!  The exhaust becomes very hot. Caution! It will cause severe burns! 
!  Before driving again,  review  the  checklist to make sure that your  kart  is still in good 

condition and fully operational. 

 

It is normal to see the water temperature increase after stopping the engine, because the wa-
ter pump is not running any more, and the radiator is not cooled by any wind. 

 

Lubricate the chain with chain lube immediately after driving. While still warm, the chain ab-
sorbs  lube  more  readily  and  lasts  longer.  Make  sure  to  lube  the  chain  links  as  well  as  the 
running surface of the chain. 

 

The  lifetime  of  a  battery  is  greatly  reduced when  it  is totally  discharged.  Charge the  starter 
battery regularly 

– even if it is not empty. 

6.5.  Transportation 

Fuel can sometimes escape from the carburettor or the fuel tank during transportation 

– es-

pecially if the kart is transported vertically. Always empty the fuel tank and the float bowl of 
the carburettor before transportation. 

!  When removing parts like the carburettor or the exhaust from the engine, you should 

close all ports airtight.
