I have watched several video tutorials about how to service a fork and decided to try to open and clean my Suntour Nex 4610 fork . I didn't do anything besides cleaning and lubricating the tube. I didn't touch the spring or the suspension cylinder inside. But now when I reattach the two parts (without tightening the bolts) the fork stops moving even when I apply a lot of pressure.
What could be the reason for this problem?
