how much topend will u gain with a 15 tooth front sprocket, and how much bottom will u loose. and how much accel will u gain with a 13 tooth front sprocket, and how much top will u loose. thanks-rider1169

 

I would also like to know.

 

I will be testing this within the next couple of weeks.

 

i explained this about a week ago!!!
how do you explain how much faster you go when you change front sprockets...? there isnt a scientific formula to tell you how many feet per second faster you go with a smaller sprocket. you will go a little bit faster.... but dont expect it to rip you off the seat. you will probably loose 3-5 mph on top.

the larger sprocket is the same scenario... you will accel a little bit slower... but not much and probably gain 3-5 mph on top.

 

couldnt you clock it before and after then dyno it before and after
