Fuel Tank Wobble

When I put my new K&N air filter into my 6th gen and torqued down the bolts at the front of the fuel tank i noticed a slight wobble of the tank side to side. It may have been there before but i certainly hadn't noticed. now i'm a tad annoyed by it. It's clearly due to the clearances of the through bolt at the rear of the tank around which it pivots when you raise the tank. I am wondering if you guys experience this too? if so does it bother you as much as me? and how would i go about fixing it? every bolt on the tank assembly is torqued to spec.

Check the parts fiche. The 4th gen tank has two rubber pieces at the front.
(and 2 between tank and frame beam, but they are not as critical for wobbling)

Is  the  top  of  your  airbox  hitting  the  bottom  of your gas  tank ?

The bolts each have a collar in the center of the rubber grommet.  When the tank is propped up mine seem to fall out fairly easily.   Have a look with the bolts out and see if you can see them.  If not, they're probably around the airbox someplace. 

my air box isn't hitting and the collars in the rubber grommets are still in place. I assume the rubber is what is allowing the free play in the front of the tank, but the rear seems to be the main problem, around the bolt it hinges on.

It  would  bother  me ,  does  it  rattle  when  you  hit  bumps?

You  got  remember  it  was  fine until  you  replaced air  filter.  So  something  must  have moved  underneath .

Any  chance   the  previous  owner  had  something  at  the  back  of the  tank  to  stabilized   it  and  fell  off  when  removed  the seat  and raised  the tank ?

there's no rattle and it may have been there before i replaced the filter. it is just the slightest amount of play when i rock it back and forth. feels like rubber giving a bit. i feel like adding a stainless steel washer on either side of the through bolt in the back may help tighten things up.

Good idea  ...
