Let us just stick to the fact that the maintenance was to be sure of your investment to some extent - but mainly for your daughter's safety. That is what counts.
From what I know of my own 3 daughters and other youngsters I would say let her decide on the emission stuff, she may not want a hot bike, nor necessarily want to add pollution to a world she has to try to thrive in, without Dad () and as a parent herself one day hopefully.
