Junior Dragster...

....have a question for anyone whose kid races them. Could not help but notice lot of the parents that are helping the youngster up at the tree cycle the ignition...some do it several times. Of course the one parent that I asked did not do it....and had no clue as to why the others do. So...could someone educate me?

I have a few buddies that race bikes...after doing the burnout they will shut the motor off and then restart it...guessing it is for data logging purposes.
But the JR Dragsters don't let the motor come to a stop...they just flip the toggle switch...
