I highly recommend acf50, a light coating on engine, exhaust, nuts and bolts and electrics. . Well everywhere really except wheels, brakes and painted /plastics which don't rust. Only need a thin layer wiped on with a rag or sprayed on and wipe the excess off. I've used it since day 1 as I used it on my older bike before my strom. Not a patch of rust on her ,except my brake disc which comes off on a ride and a dirty rear sprovket I just can't get clean.
