Loosen the locking nuts (20mm) under the riser first. Believe me they are torqued tight, then remove caps and handlebars. Now remove the locking nuts and pull the risers out. When I installed my phat risers I used the rubber gaskets from the old risers. I had a vibration (why I posted this), I went back and retorqued the nuts and that took the vibration out.::bluethum:
