Hi Guys!

I am new here so I'm sorry if I am doing this the wrong way. I have a Buell XB12S for a couple of years now and I love it. A few days ago I got an error on the cooling fan. (did count the error code) So I did take a look at the fuse, well he was done! So I took a closer look at the fan and found this piece of rubber thas was stuck between the blades. It doesn't seem broken or something. Also there is a letter R on it. Who knows what this is? I think it should go back right? (The fan just works fine again after renewing the fuse)
