update:
So it has been exactly 2 months and i just ordered a 36 tooth sprocket for my axle .
that would give me a 3:1 gear ratio for my really lightweight kart. With 4:1 ratio AND my newly aquired .290 cam @ 104LSA this tire REALLY loves to spin before it gets traction now. SO.. that being said, new gear ratio it is. and also will be purchasing a live axle kit.
