First of welcome to the world of the Banshee's you will love the bike. 2-stroke oil you should mix at 32:1, look into getting a good reputable oil like cator 927, amsoil, etc. As for the kick starter if it is jam, you may have thrown a bearing in your crank. If so you will have to replace the crank, which could be pricey if you dont know how to do it. I would like recommend you pickup a Clymers repair manual, which will assit you in repairing the bike. If you have any more questions HQ is great site for some assistance.
