I tried calling epi but they are closed for the weekend. I want an aggressive set up. Now before you chime in and say you should have ordered a custom kit from rtr or HP I only paid $90 for this kit brand new!! I was wondering what difference is in spring settings. it says 2 on the helix and 3 on the clutch. What will other combinations get me? I trail ride and little jumping. I would like it to wheelie easier too. Is there a better setting for my style? I also bought a rzr belt.
