check this out. i think ive come up with a redneck solution to this problem
SO i made a bracket (in pic) that i am welding to the frame tomorrow.
Once that is welded onto the top tube i am using two strips of old tire side wall to use inbetween the tank and bracket i made. Drill two holes in each strip and put on the tank. then ill mount it softly enough to avoid vibrations and loc tite the nuts that hold it on.
This would get rid of bad vibes and hopefully work. ill let ya know how it goes
well it wont let me add that pic again . lame. but heres the link.
