Sprockets

[yzrider04]

I bought my kx used and and I know the sprockets arent stock...stock is like 48......mines 57 in the back and 14 in the front......is this causing me to have less topend....and how can i gear it to make it quicker???

Yes, the larger rear sprocket will cause a loss in top speed. To regain top speed you will need to go with a smaller rear sprocket or a larger front sprocket. You can also change the tire/rim diameter but I don't know what's availible for bikes.
