Help with my parents!!!? - how to replace a snowmachine start cord

I have a few new snowmobile a few months, and my mother still does not know how powerful he is, but my father knew. So my mother discovered his 800 and has 140 hp, so now shes doing my dad sold! Reasons: too big, too powerful, can not handle (like she knows what can or can not process), and it has not (even though) we even get in the winter. This bubble is completed, the dream of my sled, my most valuable. I can not anymore.

For those who know, the one or two things about snowmobiles
He is a 2008 Arctic Cat Crossfire 800 EFI Sno Pro
replace and want a Arctic Cat F6 EFI LXR 07

I am a girl of 15 years, but I am much stronger than most girls my age and I have tons of driving experienceEC (I have lived since the driving age of 6 has a lot to my father only gaddamn the cause of my mother, I was familiar with the background)

As I can not convince me to do this, it hurts Freaken and I can not give up!
