I have a 2012 superglide coustom it has 100 miles on it when I go over a bump it sounds like something banging sounds like it is under gas tank but I've check dont see anything loose any body have this trouble before.

 

Check your Jiffy Stand. If the bike was just prepped they may have not positioned the Rubber Bumper correctly. This happened on my 06 SB and every bump. decel or what not I would get a banging, rattle from the stand contacting the Frame.

Twisted the rubber bumper down and issue solved.

For me it was the gas tank bolts up front that were not tight

 

Somebody please speak up if this is wrong, but I thought I've heard that loose steering head bearings could cause this, and that many times they are too loose right off the showroom floor.

 

Mine was the front tank mount loose.

 

2012? Back to the dealer....

 

Thanks everybody fpr your replys I found the problem it is the front bolt on the gas tank.
