Anyone on here use V force Reeds on an F5. Just wondering if the performance gains are worth the effort and $$. Also what is involved with installation and are there other things to be done when you install such as jetting or carb tuning. I read good things about them but would like the benefit of you guys experience. Also are there other reeds that are better? I have opportunity to buy a used set from an F7. I think they are the same?
