Last year I bought a 02 Grand Touring 700 Sport with only 125 miles on it. While I was polishing the exhaust and belt cover, I noticed the paint on the head is brittle and peeling off from the sides of the head. I'm not sure if it’s from when the sled was sitting and oxidation got under the paint. The engine case looks a little oxidized; white powder comes of when rubbed. Has the peeling happened to anyone else’s sled?
