I have a concern some of you may help me with...Have been having some really hot weather here in Ohio...Yesterday after returning from about a 100 mi. ride I pulled into garage and dismounted..I heard some gurgling sounds coming from the tank and some strong fumes...I opened the tank cap and observed the gas boiling...This has happened before under extremely hot conditions....Has anyone else experienced this and is it a concern?...Yes the heat shield under the tank is intact...Thanks in advance for any help or answers....Bill
