    Look from bottom cam to top idler wheel along the string and see if cam leans out. If not, make sure idler is straight a full draw. May have to twist left split. I don’t think arrow is too stiff. A left tear is a horizontal nock travel issue, and weak or stiff is usually a vertical issue with most single cam bows.

      My cam and idler look good. I think I have to twist my left yoke and untwist my right

        Found a video on YouTube on how to adjust yoke twist without a press. Twisted my left side and untwisted my right and I’ve just about got it!

          That looks pretty good. My current bow doesn't shoot a clean hole through paper but bareshaft is perfect at 30 yards.. so I wouldn't completely trust a paper tune.

          You also need to shoot a foam target before you start adjusting for entry angle. The rags in a bag target can make the arrow angle look bad when it's really hitting square..

            My target is a foam target. It’s turned sideways so it’s hard to tell. I didn’t think about a bag target affecting arrow angle but it makes sense.
