I was checking the tire pressure yesterday and noticed some brown discoloration on my left side exhaust pipe. Upon further inspection I realized the dealer left the clear plastic protection film on the pipe that's used during shipping. I only had about 250 miles on the bike and was able to peel off the plastic and no harm was done to the pipe. I would imagine if the plastic was on there long enough it would have melted into the pipe. I thought I smelled something a little funny, but thought it was just the new engine. If you have a new F6, check those pipes.
