I'm leaning toward the 1/5 turn. I wonder if it'll be enough.
What do you have?
How do you like it?
Where did you get it from?
It looks like I can make my own, but I haven't found enough info.

 

Good luck with this post. I posted something almost just like this a while ago and didnt get hardly any input from anyone. I know there are people who have done this mod. I am still trying to decide what to get but I am leaning towards the 1/6 turn and I will do it next winter when I replace plugs, check valve clearance, and sync the throttle bodies. There has to be one that more people favor and for specifis reasons in the F4i. Is 1/6 too much? is 1/5 noticable over stock? These are things I would like to know but no one has any suggestions. I know it is all rider preference but there has to be somebody that had done this mod whether it be 1/5, 1/6 or both.

 

I guess I'm just gonna have to do both lol.
