Ignition System Check

1.  Remove the spark plug and reattach it to the spark plug lead.
2.  Push the electric button “START “(yellow button).  Apply the rear brake 

lever to make sure the rear wheels are locked.  If the ignition system is 

operating properly, a blue spark should jump across the spark plug gap.  

If there is no spark, take your machine to your service center.

COMPLAINT:  Engine stalls

1.  Make sure there is enough fuel in the fuel tank.
2.  Check to see that the spark plug is not fouled.  Remove the spark plug 

and clean it.  Replace it, if necessary.

3.  Make sure the fuel valve is not clogged, and the fuel tank is not clogged, 

either.

4.  Check the idle speed.  If necessary, adjust it using a tachometer.  The 

correct idle speed is 1400~1600 r/min.

 

WARNING

Performing the spark test improperly could be hazardous.

You could get a high voltage electrical shock if you are not familiar with this 

procedure.

Do not perform this check if you are not familiar with the procedure.  Do 

not point the spark plug near the spark plug hole during this test.  Do not 

do this test if you have a heart condition or wear a pacemaker. Do not 

perform this test near any open fuel containers for near fuel which has 
spilled on the ground, on engine, or any part of the ATV.
