So just got done riding and i was turning the fuel off and i could feel heat radiating from the engine head, im paranoid about my engine being alright (running with enough oil) is this normal. AND one more quick ? when i go by the back of the quad to push it into the barn i smell almost like a burning smell by the silencer i want to say almost like burning rubber maybe the seat is heating up??? Im new to 2 strokes, so this is gonna sound weird but can someone TRY to describe what burning 2 stroke smells like. :-/
