scrod I cannot get rid of some play in my headset. it seems to be coming from the top dust cover area. I took off the stem, spacers and cover and then put them all back on and tightened down nice and good and I can still get a little bit of 'lift' when I pull up on my handlebars. any ideas? I have next to no experience installing headsets, it was done by a LBS. it's an FSA threadless headset if that matters
