One of the hanging bolts fell of my stand , lucky for me it was at home as i pulled in , what i found was that the 2 retaining bolts that hold your spring hanger on that form part of your sub frame were loose , which is not good , so be aware if you have a centre stand to check the bolts , i think the bolts that are supplied are not long enough to get advantage of the lock nut , i replaced one from what i had but will be replacing the other with longer one and using Lock tight as well
