How does a stiffer spring in the secondary effect a snowmobile? Does a heavier improve or hurt the sleds backshift? I am curios because the F5 comes with a green spring and my old Zr 500 came with a yellow. The green spring is much stiffer then the yellow, it seems like a lot for only a small increase in horse power. Also the F5 comes with much heavier weights is the extra weight used to just counteract the stiff spring? It seems to me that the green spring is over kill and just causing alot of unneeded resistance. I guess I'm asking alot of questions here but if anyone has any opinions I would appreciate it
