lads...im running Sx200 gearing in my GP
currently on refurbing the engine fitting a Mick Abbey tuned barrel modified for reed valve, using 30mm carb on LTH manifold & JL-4 pipe
& wanna give try with 15 x 47 drive setup

The SX 200 gearbox is a good all round gearbox, but the engine needs some pulling power to pull 4th especially two up!
Changing the crownwheel to a 47 tooth improves the top gear ratio too 4.91:1.
