Yeah, I could see over it, but I have not tried it on the Zongshen - I sold it with the FZ-1. I really wish I would have kept all my gear, in retrospect.
Did you have to tune the carb to get into the 70-80 range? My bike runs well, and has only seemed to improve on acceleration, but, my top speed is actually lower than when I first started riding it, maybe 65max. I tinkered with the fuel/air mixture a little, but may have done more harm than good. Have not checked the plug for indications yet. Exhaust smells and looks clean though.
