    Ever since I started using the bike, any time I stop it, it leaks tons of burnt up black liquid. Is this normal?

    EDIT: It is coming out of the exhaust tip

    sounds like you have to much oil in fuel, are you just breaking it in. what ratio are you running

    I'd rejet the carb, sounds like you are running rich. That is a common problem with these engines, as they are jetted rich from the factory so they will start and run. If you have an NT carb, try a #66 main jet, they come stock with a #70. They take a 5mm dellorto jet, available from Sick Bike Parts, among others. Also, try moving the clip that holds the carb needle to the top groove. (leaner) Mix your fuel at 32:1 ratio, the recommended 16:1 break-in ratio is too much oil. The Chinese don't have access to good 2 stroke oil, so they recommend 16:1 because they use regular motor oil. With a good (expensive) synthetic 2 stroke oil, you can run 50:1, but may have to jet down some more due to the added richness.
