Just wondering what effect a different helix would do on my xtc 700. So far its stock besides drilled out muffler and reed spacers. Plan on doing some clutch work this spring. Does it affect acceleration at all? From what I can find all I see is it lowers your rpms
 

I found a used Apex helix with less then 500kms, for 50$ Canadian. Very noticeable improvment in over all performance and back shift.
