First post was 30th of June, we are now at the 31st of July, so 4 weeks have passed. Unless the bike was registered in someone elses name, it is probably fair to say to you "Relax" and stop worrying. You were not stoped at the time. Any NIP should have been sent out within 14 days you have alowed a couple of weeks additional leeway, I suggest you breath easy now
As said you are past 28 days so hopefully OK unless it is a new bike, new reg, or you haven't told DVLA of an address change etc. Keep your fingers crossed Was much easier when they had to send by recorded/registered post, but apparently the Courts believe that letters are still delivered the next day if sent 1st class. So quaint http://www.motordefenceteam.co.uk/knowledge-Guides/n-i-p.htm
