I own a 2008 America. I purchaced the bike new in August of last year. Within a week or so of purchacing the bike I noticed bluing on the right exhaust at the first bend out of the engine. The left exhaust started to show a slight brown color but nothing like the right exhaust. The amount of discoloration has stabilized on both sides but the difference in color is very noticable between the two sides. The right side is cobalt blue and the left has very little blue and is mostly brownish. The bike has right at 5000 miles on it and is running great. However, last week I noticed a very faint "tick" when I would let off the gas to decelerate. Since then The "tick" has become progressively more loud. Many times there are two ticks and sometimes there are also "ticks" when the clutch is released fully after down shift. Any experience and/or knowledge on this you are willing to share is greatly appreciated.
