front sprokets???

[motochain55]

I just got a new set of rear tires and there 18x10-9(smaller than my old ones) so i have no top speed at all. Would it help to add a tooth on the front sproket or do i need more?? And also if i change the front sproket do i to change the rear number of teeth too? Thanks guys

i would just put a 16 tooth up front & leave the rear alone

put a 36 in the rear or a 16 in the front, ull notice more top end with the 16 but more accel with the 36.

1 tooth in the front equals 2.5 teeth in the rear. so decide what u want more
