I've just noticed on my new to me RT that the fair shields on the backside of the fairing by the exhaust manifolds are brown and toasted, plus I have a blister the size of a half dollar on the left exhaust fairing. I felt the plastic after a short 5 mile ride I take to work, some stop and go but not a lot of sitting in traffic and even on a cool morning that plastic gets hot! Is this really normal or am I missing something engine wise. I'm near my 24k maint and the previous owner did valves and sync at 13k. I did put fresh NGK plugs in at 21k and changed to oil to 20/50 amsoil full syn.
I just don't want to damage the fairing any further and catch fire!
