banging under tank

[slowrider60]

I have an 02 r1150r and just completed my 24k service. All went well accept i hear an occasional bang under the tank after a good size bump. I have taken the tank off and inspected and do not see anything that can be the cause. All the gromets are back in place and the rubber guides are in place. The battery strap is still in place. Does anyone have any ideas?

Loose screw holding the tank? Anything loose inside the tank (fuel filter?)? That would be my best bet.

Fuel sensor float? That'd probably go away if the tank is full. Stretched-out battery strap? That's hard to check... Loose tools under the seat?

Maybe the rubber bushing at the top of the front shock mount has deteriorated and the rod is loose in the stubframe. You can see it by looking up inside the shock tower with a flashlight from below and behind the headlight.

All your ideas seem to be good ones. I had the dealer install the plate for the fuel filter/pump because I was having some issues getting back in place properly. I will bring it back to the dealer for them to look at.
Thanks for your responding!
Have a happy new year.

Like omg1010 said and given that I always suspect what has recently been changed, I suspect that you'll find it to be related to your dealer's latest repair - something either in the tank or fastening it.
