Hey Kristin, you getting stuck seems to be lack of riding experience... I know you only started to ride a few months ago.
My statement is based on the fact that over this past presidents weekend I rode for all 3 days a friends '05 LT-Z400 100% stock rolling on ITP SandStars 20x11r10s 3-4lbs psi and never had a problem getting stuck. I literally weigh 2x as lil'o you, at 240lbs.
Pulled Banshee 1/2 way up in 3rd before having to grap 2nd and Comp about 1/3 up before grabbing 2nd and held it ALL the way to the top..
That thing had plenty of torgue for my chubby butt. Don't be afraid to work the bike, get them RPMs up. You'll see has you ride more!
