video question part 1 & 2

[scootx]

hey all i am new here and i was wondering if my youtube link will work here ? i recently installed a 100cc big bore kit on my 50cc scooter..gy6 139qmb.. and i have been having some issues like oil drips through the valve cover, my air filter gets LOTS of oil it..(how can i stop that?) and my engine seems to overheat a little because after about 20 minutes of riding with the new bore kit, it seems to start making strange noises and wants to "shudder" at certain times and it will also slowly get louder and louder.. hmmm.. anyone have any tips of where i went wrong? i left EVERYTHING else the same although it takes 14.7 volts or more to start it, so i will need a stronger battery.. but anyway here are the links to the videos:

thanks all
