I was at the track Sunday, just after practicing I put my bike on a shop stand and went to get a drink of water. Well my bike fell over and my helmet wedged between the filler cap and the ground and the just at the base of the filler neck the plastic broke. Its broken about half way around the base. What is the best way to repair? Superglue, Epoxy, JB weld? I know I'll probably need to get a new tank, but prices . Thanks a Bunch.
