I would like to make my bike go out like a bat out of hell. right now i know i have a +2 rear sprocket, not sure what the front is. also not sure how to check what my chain is. but anyways im not really concerned about top speed, as long as its at or over 120, anyone have any setups they reccomend to make my bike get out of the hole a lot faster?

 

-1 in the front is the obvious thing that comes to mind, and don't even concern yourself with chain length. Are asking specifically regarding sprockets, or overall? How far are you willing to tear the bike down?

I've got a stock sprocket setup, and I can hit 60 in a little over 2.25, and I don't even know what I'm doing. How much faster than that does a bat out of hell go?

 

i am talking just about sprockets, not looking to tear apart the motor any

 

-1/+2 is the preferred way to go. Others choose to just throw a +5 on the rear.
