Do I need to loose 80lbs before I can get it to go 70? What's the deal???

Weight (yours) and power will be key. Also, do you lay down forward for aerodynamics? You could try a new head or porting your stock one. The thing with Chinese dual-sports is most people do what you did with yours, exhaust, carb, and gearing, but you don't necessarily get much more top speed out of them, but rather lower revs, making your ride a bunch more comfortable, but not much faster, at top speed. Megadan has advice on the matter based on his Hawk, and he uses a Nibbi carb and has done head work on his Hawk.
