Bumpy roads make my tank rattle

[Wheel yumz]

So i have a 91, and pittsburgh roads are about as bad as anywhere. Everytime i hit a potholes or cross RR tracks, my tank rattles, REALLY loud. I have taken the tank off, replaced all rubber mounts, including the c shaped one at the front of the tank. The tank is mounted solid, but still has a slight bit of play (which i read was right). The only time it makes the noise is when i hit a hard bump, which are everywhere, and sometimes unavoidable.

I almost seems like something inside the tank is loose. The fuel gauge works properly, so i dont think that is the problem.

What else is in there? I have no experience with gas tanks.

Any suggestions or experience with this annoyance?

maybe the float inside?

your wiring or cables (throttle/clutch) may be vibrating or bouncing against the bottom of your tank. Try removing your tank and look around the entire surface for an area that shows signs of scuffing or wear on your paint. If you have already done this maybe try stuffing a damp sponge underneath your tank and ride around the block, if the noise is still there then your problem is somewhere else. Don't ride too far or leave the sponge in there unless you are sick of it and looking for an insurance claim.

Mine used to do this. The rubber stopper that the very front lip sits on was missing on mine and had a bunch of electrical tape wrapped around. I would say either add some support there, and/or tighten the 2 tank bolts under the seat.

Your avatar is great. My buddy had that on his myspace page, and it would bob at exactly the beat of a song he had on there..... Dash Speaks "Problemas"...... I may have watched that 3 times a day for a month.

BTW- If anybody on here really likes hip-hop, check out Dash Speaks and Nickname, the duo is called "Bad News" on Screw York Records www.screwyork.com . Download the album there, it's worth it, for sure.

So, did you fix it??????????

The C-channel at the front is also known to strech open a bit, try pinching it closed a little so it gets a tighter bite on the frame mount. If you havent resolved this already.
