Just returned from a cross country trip to find these new splatters on my exhausts (both sides.) Kerosene won't make a dent in them. They don't seem to be "scrape-able." Any experts out there able to identify the cause by looking at this picture? Any experts know how to make theses spatters go away? Thanks. IMG_6585.jpg
 
Answered my own questions

A. Never got any help or suggestions from the forum as to what caused these spots on the exhausts. B. Easy Off Oven Cleaner, brushed on liberally and left for ten minutes on cool exhaust cones, then wiped off with damp rag - eliminated 90% of the problem.
 
That area is prone to carbon build up. Not sure what the spots are. Previous bike I painted those inserts with black BBQ paint. With my 16 model, I painted the entire end cap with same paint.
 
Tar spots

I use Lacquer thinners to remove those tar spots, only used on the exhuast, please don't get thinners near your paint work !!!
 
Spots on exhaust

I've used mothers on the exhaust ends..that rough aluminum and it's worked great....for whatever I've had on mine anyway.
