Looks like you can get any kind of stand you want, new, for less than 90. Looked in my Motosport Outlet Mag and nice center stands that lift your bike off the ground are around $80, and a prop stand that you lean the bike against is only $20.
Sounds like your bike is flooding, not fouling, if it happens when you crash it. You definately need to hold the throttle wide open when kicking. You being 14 makes me think, you may not weigh enough, to make it an easy kick. If you feel like you're putting your foot up by your ear, that also makes balancing a problem. Try putting the left grip against a tree or something, so you can stand up, and so you can get as much as possible into the kick. And its always less trouble, in neutral. Also, slowly push the kicker around until you feel the compression of motor stop your foot. then wind it up for a hard kick. Hope that helps, Bud.
