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.
When ridewrap developed their wrap, they had a shuttle guard. If you reach out to them, they'll send you a replacement free of charge without the cut out.
Do you have a frame plug for that hole? I know the 181.1 came with plugs but it seems like the 181.2 did not receive plugs.
