I just noticed on my new xcf that when the bike is on a stand and the rear wheel is off the ground I can move my shock spring up about a 1/4 inch until it hits the spring adjustment ring. When the bike is standing on the ground the shock spring is tight against the adjustment ring. Is it suppose to be like this? I noticed this after setting the race sag on my last ride as I had never looked at it before. Please advise as I don't want to ride the bike if it is not suppose to be like that. Thanks Guys.
