I didn't do anything other than have a problem lol. My bowden cable adjusts very easily with just my fingers. I turned it all the way in and it shifts smoother and at lower rpms. I had to go to work so I just left it and when I get home I'll play with it a little more. I guess I'll eventually find that "sweet spot". Thanks again for helping me out in addressing the issue. Now on to the sluggish start. I'll continue that though in the other post.
