If there is play in you Headset then all you need to do is loosen off your stem bolts that grip the stem onto the fork column the tighten the top screw until this solves you problem. if this doesnt work then it may of bottomed out because the fork column isnt short enough, the reason being is your top cap need room to sit on the top of the stem. the best way to solve this is obtain a 3mm spacer from your bikeshop etc then slide it with the rest of you spacers. if that dont work your bearings might be upside down (you never know) lol. if that dont work take it to your local bike shop and ask them if they canresolve the problem Carl
