Today I was washing my bike and I noticed that the mudflap under the back fender in front of the rear wheel had melted the last time I rode the bike. It is all melted and looks like it liquified and started to drip where it comes close to the pipe. It never touched the pipe (there is nothing melted on the midpipe, and it would look different if it had touched it), my pipe just got hot enought to melt it. I've never seen anything like this before. Has anyone else? Here are some pics I took with my phone, sorry about the quality.
