There is a lot of synergy going on in the back end. Everything has to be set just so. How I drive has the biggest influence as when using the first Harley compensator I had to really make sure that engine speed and shifting points really had to be dead on or you suffered the consequences. The Centa unit behaves much better. I'm working the accelerator to make things mesh on down shifting and, more importantly, up shifting.
I have never had it ratchet or slip a tooth and I drive the belt on the loose end. I am able to twist the belt 90 degrees.
I just changed out the rear tire and it has taken two weeks of fiddling, driving hard and whatnot for it to settle.
Right now, with the Super Max overlay, I get a mild chirping with torque spikes at around 3,300 rpm where the torque maxes out. It seems to be related to humidity more than anything else. When the air is reasonably dry it doesn't happen.
I wish we had the six speed. There's a lot of wasted space where you are either lugging it or over revving it to hit a certain speed. Big gaps.
