How do I fix the kickstarter from rattling and being so loose on my 01' banshee?

I have an 01' banshee and am currently at sea level, running a 310 main jet and the needle clip in the 3rd slot. I will be heading to St. Anthony dunes in Idaho the end of June for a week, which is at an elevation of 5,400 ft and am wondering how far do I need to adjust the jetting? Also what mix ratio do you recommend, I use maxima castor 927 oil?
