You will get some SLIGHT burning smell/smoke on a new scoot. The paint on the exhaust, clyinder, ect.. will tend to "burn in". Also the manuf uses a compound similar to cosmoline on the shiny bits to keep it all looking good. A through wash down w/ dish soap will minimize this. I use spray on wax by Turtle Wax when I clean up, and get the same smell for a short while. Just to be safe, I would suggest Checking your brakes, FT/RR to see they spin freely both when cold, and hot. Also check ALL of the fittings on, and around the engine. If there is any kind of a leak it should be easy to spot on a new scoot. A tiny leak will tend to burn off more than leave drops under the bike
