It will depend on the situation or personal preference. If you are lightweight with no serious modification of tires enlarged and your road there is flat go to 43 to 39. But seriously, If your heavy and your rims and tires are large go to 45 above. Less stress for the engine. Below are some things/knowledge I knew about sprocket change results.

The bike doesn't really care what sprocket it has. "Best" sprocket depends on the rider's preferences and ability. If you're spinning out and want more top speed - get a smaller one. If you're bogging down and slow off the start - get a bigger one.
Any size will work. What'll work best depends on what you want it for. Higher top speed - go for a big sprocket. Quicker off the start - go for a smaller sprocket.
14-38 is the best sprocket combination, using an iridium spark plug or any upgrade of spark plug. it will surely deliver power and speed. and you don't need to open your engine for more upgrades.
