Possibly a bearing put your front brake on and compress the forks a few times see if there your problem. Pull your bike onto its side stand so front wheel is off the floor easier if you have someone to do it, and spin the front wheel see if there's any movement will maybe feel it if you out your Hand around the forks. Then hold the wheel at the top and bottom on a full lock and check if there's any play. Finally check your head bearings are tight. Sent from my iPhone using Tapatalk
