I packed some Guinness in the topbox [Guinness tastes good warm] Rode up to the Bald Eagle Bastard's 7 Mts campout. Had a blast. Unfortuanatly the nitrogenated cans also had a blast. All over everything in the Givi E-52. I suspected it might be a problem, but took the gamble and lost. Just posting this to maybe save the next guy from some grief.
