just go to a 7 tooth on the front if you have to change gearing,imo leave the 6/68 gearing you have now,if you only change the front pinion you won`t have to get another chain or resize your chain also changing gearing hurts either your top end or take off if you want it to top out at a faster speed ,you hurt your take off,if you want it to take off faster,you hurt your top speed |
