thats not the trans thats hessitating, you should try leaning it out a little more, may be loading up. it is shifting, you can see and hear it when it does. running under 200 is a little on the cool side.
perfect answer.
I actually have been playing with the 2 speed a lot lately and trying to make it shift more positive. Polishing the inside where the arm rides is a lot of trouble but it does help. Also if you take it apart make sure the spring ends are flat. If you take a small object and put it under the arm and move it. If you feel a rough spot moving that arm the shifting will be erratic. Smoothing the spring end that pushes on the arm will stop that.[:-]
