I think I'm even riding wheelies at will in 2nd gear, cuz I'm missing first... Not sure though, seems like this 3-speed has thrown my tune off a tad I think.. Anyway, it's been wheelying at will since tank 1 - not uncontrollably, but on the contrary - very controllably.. My slipper is 3/4 out.. If you really want wheelies tighten the slipper...
