@5amerto first off id try 14 45 and if that didnt work put vforce reed valves on it cause it needs new ones

@ben1996ful slightly it would be hard to notice, dont play with the back if you really want a change go down in the front, i run a 52/13 on my freestyle 125sx and a 14/48 on my rmz450 motocross bike 450 still destroys the turns and has killer top speed in straits, where as the 125 gets full speed in like 250 feet, but it has crazy accel for short run ups to ramps and pulls it around really fast for backflips, you really just gotta mess with it all until you find what fits your riding style

i run 14 front, 45 rear, on 04 yz250f that has stage 2 cams and 290cc kit, my bike does 93 mph clocked with out losing a shit ton of bottom end i mean, if you where running stock gears on a 250f 13/48 my 1st gear is like your second gear yet your 5th gear will only let you hit 75-81 and my 5th will hit 93 :)

if i add one tooth on the rear sprocket will that give me better acceleration
