Noises drive me crazy. The reason I bought a big twin was so I could do my stay in Purgatory while still on earth. The gas cap cover on my Suzi is an on and off buzzer. I put a couple of dabs of clear silicone on the rubber bumpers that come into play when you lock the cover. Ah, the horrors of haveing a bike that is made out of metal parts. Ear plugs work nicely . . . .
