Did you have a bike with a m1 motor? If so, was it similar in rattle or less. My buddy's m2s rattled after the 3rd ride, not as bad as the m1 but noticeable. Im only 40miles (crestline plaid) in but so far *knock on wood* no rattle.
Yours may come with it but best to check with Troydon. Those who got the frameset and chose the fork as an option specifically say a starnut and mudguard is not included.
