Try to make sure you keep your weight moving/leaning forward. Also when your wheel taps the bike sort of stops spinning but make sure to keep your weight spinning around. It will feel much better with a slow carving kind of spin as well, and not just twisting like mental. Good luck and enjoy, its a super fun trick.
Well i was just try 180s at the parka nd i started to just go a bit faster n roll up then i would just look behind me more when i spun normally keeping my front end up more then just pivot the little bit rest
