Hey Guys i bought my XTM 140cc pit bike just not long ago and im having so much fun on it but wat made me unhappy was the gear ratio's.. so i had not much top speed. my first gear is just so low i pretty much get no wer unless i hit 2nd so i thought if i change my 43t rear sprocket to a 41 tooth will that make any difference or do i need sumfin a lil smaller?? 
its running 16t/43t atm. with a Lifan 140
