With your current stock 15/36 sprockets and 94-link chain, your tach will read 3,890 rpm in 6th gear when your speedometer reads 70mph.
When you change the rear sprocket to 43-teeth (which requires a longer 98-link chain,) your tach will then read 4,647 rpm in 6th gear when your speedometer reads 70mph.
You'll be reving higher at the same road speed - in any gear. You'll also gain more torque for starting-off too.
Clear?
