I live in South Carolina so I don't see salt on the roads very often. I just purchased my new wing two weeks ago. The weather has been bad so I haven't had a chance to ride it much. I took it out for a ride a few days ago. Went up to the North Carolina Mountains. The roads were dry mostly with an occasion wet spot. The roads had been salted a few days before. Rode about 102 miles on these roads. After the ride, I rinsed the bike off and wiped it down. Today, I noticed the underside of the engine looked dirty. When I wiped it down, what came off was large flakey pieces which would crumble in your hand. IS this road salt deposits?
