6-  STARTING AND STOPPING THE ENGINE 

 

Press the green button on the steering wheel to start the engine. 

If the engine cannot be started, stop and try again (check that gas gets into the carb.). 

Short and frequent tries are better than long ones. 

In case the engine can't be started, refer to the Sect. 17  ” Troubleshooting". 

The engine can be stopped by pressing the red button on the steering wheel. Keep the  

button pressed until the engine has got to a complete stop. 

 

 

7-  ENGINE BREAK-IN 

 

The break-in of the engine must be performed following a few fundamental rules. 

 

1.    Adjust the carburetion. Start with an adjustment on the rich side. 

 

2.    Warm the engine gradually for about 5 minutes at half throttle, making some laps 

at  low  speed,  closing  and  opening  gently  the  carb.  throttle  (if  a  tachometer  is 

installed never exceed 8.000 RPMs). 

Never keep the same RPM for a long time. 

  

3.    Progressively increase the speed of the kart for 5 minutes at ¾ throttle opening.  

Never keep the same RPM for a long time. 

 

4.   Increase the speed for approx. 5 minutes at max. speed, with throttle wide open 

and making the engine rich at half straight (cover with the hand for 

an

 

instant 

the 

holes on the air filter, keeping the throttle wide open). 

     

  

     

ATTENTION:

 

       

Once the break-in is over and the engine is cold, check the torque of the exhaust 
header nuts as, during the break-in, the nuts tend to become loose (refer to the 
attached  table). 

 

 

8-

    

INLET SILENCER 

 

Make sure that the inlet hole on the filter is towards the upper side and that it is not 

plugged. Make sure that the clamp on the carburetor is not loosen and that the filter is 

well fastened to the chassis rail. 

 

Once a while, clean the inside from oil deposits. If necessary remove the rubber filter 

fitting and clean it with gasoline or solvent. 

 

 

 

 

9-  RECOMMENDATIONS ON THE EXHAUST SYSTEM  

 

Always make sure that the springs are well hooked and in place. In case of breakage, 

replace the broken spring. 

Never race the kart without the 2 springs in place, 

as

 

otherwise the exhaust pipe could vibrate beyond control. 

Every 10

15 hours, open the exhaust pipe end and make sure that the holes on the 

internal  counter cone are not plugged.
