I just got my new sled. I put 4 miles on it. Question is, it smells like burning rubber after I shut it down. Nothing it rubbing, hyfax are not sticking and the smell seems like its coming from the exhaust smoke that trickes out of the pipes after its off. Is this normal during break in? Again, its brand new with only 4 miles. I remember my rtx had something like this but this time its quite noticiple. Normal or not?
