I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for kick start that I've seen before include "Get going" , "What gets a biker going" , "given sudden impetus" , "get moving" , "taking power supply from the boot" .)

I've seen this clue in The Hindu.
