Gear ratio vs speed

Hello everyone! I have a question. Some one knw whats the equation to take final drive ratio (ft/rt) vs speed (mph). I recently change the gear ratio on my r1 to 15/43 nd it seems to b great on launches, roll on races but when I shift to 6th gear it dies. They pass me easiely. I have a couple of upgraet such as a power commander full yoshimura bmc air filter air by pass nd well the sprokets. Im asking this cuz I wnt t ol chage again my sprokets so I can have nearly same launch but more top end. No discution it has lot of power from 1st to 5th Ive smoke almost all 1000 I have race but when I shift 6th they take preaty fast. If anyome have any suggestion in gear ratio welcome!

Ty all
