did it give you better response off the line? Where do i get info on thundershift weights? what was your stock gearing?? I want to do somthing pretty soon here I just don't know what yet .

 

I haven't even pulled it apart to count does anyone know what is stock on a 03 scrammy??

 

tbsleeper 13/36 was what came on my bike stock.

 

stock was 13-36,lowering to 12-34 help on bottom end,what i do then is to
fine tune the thundershift so you don't loose any top speed and benefit from harder lauch.

e-mail me if you want a cheap thundershift kit at brand new shape.
