I have a glitch with my Arai Vector helmet and J&M (Honda) earpieces. The earpieces scrape my ears both putting the helmet on and taking it off. The also pinch my ears a bit when wearing the lid. I could trim some of the foam out of the ear region, but am reluctant to do it in case I screw it up and wreck a perfectly good brain bucket. Anybody ever done it? I never had this problem with my other GL with the Hondaline helmets and headsets.
