Please Help About My Sprocket Combi

Good Day Members, I just want a little help about my Sprocket Combination. I read few moments ago these previous threads about Sprocket Combination Table, but I'm a bit confused.



I have Sniper Classic with 57 Vixion, 28mm Carbs, Lhk Cams and BRT Cdi but I'm still using a Stock Valve Spring.



My Sprocket Combination is 15 - 39. If you were in my position, what sprocket combination would you choose?.

My weight is 65 lbs.



I want good top speed. Thanks



Hope...
