Last weekend I removed my handle stock bars for new bars to be placed this weekend. When I removed the left grip the whole bar under the grip was very rusty. Has anyone else seen this before on the left side only? I'm thinking maybe sometime in the past the grip had been loose and worn the crome off. But I never noticed it loose and I never remember tightning it. Its really just out of curiosity that I ask, grips and bars will be new when put back together. Oh the grips were OEM also.
